How To Train Yourself To Have An Exceptional Memory
By Justin Sung
Summary
## Key takeaways - **Memory is a construction, not a trait**: Memory isn't a fixed trait you have or don't have; it's the result of how robustly you construct information in your brain, akin to building a sturdy box versus a flimsy one. [01:32], [03:34] - **Spacing effect requires active review, not just repetition**: While spacing information out aids memory, passive review methods are inefficient. Active recall and deeper thinking during spaced repetitions are crucial for long-term retention. [07:32], [07:47] - **Generate knowledge actively, don't just consume it**: The generation effect shows that producing your own knowledge, like rewriting notes from memory or turning highlights into questions, is more memorable than passively reading or listening. [09:13], [10:36] - **Test recall at the right level, avoid overconfidence**: Effective testing involves simulating real-world application and identifying knowledge gaps early. Avoid mistaking recognition for recall and be wary of overconfidence after getting an answer right. [19:19], [22:24] - **Higher-order thinking integrates knowledge into networks**: Deep understanding and long-lasting memory come from thinking about information as part of a larger network, connecting new facts to existing knowledge through methods like analogies and teaching. [29:35], [34:36]

I'm a learning coach and a doctor. But
to be honest, I think I have a pretty
bad memory. 10 years ago, I spent every
hour of every day just studying, mostly
just relearning stuff that I kept
forgetting. But today, I can learn 100
pages of a dense textbook with over 90%
retention. And the reason that I can do
that today when I definitely couldn't
before is because I spent thousands of
hours learning about learning. I learned
about how the memory works and I learned
how to train my memory. I went from
studying and constantly relearning to
studying less than before while actually
getting better results both in medical
school and for my masters. And in this
video, I'm going to share four of the
most important learning science
principles about memory and how you can
apply that to your own learning so that
you can train yourself to have an
exceptional memory. Now the first and
most important thing we need to start
with is what memory actually is. Because
if you are like how I was, you are
probably thinking about memory
completely wrong. I used to think that
some people just don't have a great
memory. I feel like I spent so much time
learning and studying when people around
me didn't have to spend that long and
they were getting better results. They
were remembering more. Things clicked
for them more easily. So clearly there
was something going on inside their
brain that was better than me. And what
I realized after reading so much
research and experimenting and reading,
you know, books like this is that memory
is not a fixed trait. It is not
something that you have or don't have or
is good or isn't good. It in fact it
doesn't even make sense. Memory is more
like this box. So if you imagine this
cube here is a piece of information,
right? You might have uh read something,
you know, someone said something to you,
you heard it, it went into your ears,
you saw it with your eyes, it went into
your brain, and it became this
information inside your brain. And after
a while, after enough time passes, one
of two things is going to happen if we
make it simple. Number one, we're either
going to remember it or number two, we
will forget it. And depending on what
happens, we say whether we have a good
or bad memory. If we forgot it, then we
say, "Oh, we have a bad memory." If we
remembered it, we say, "We have a good
memory." But this is not the case at
all. What's really happening here is
that this piece of information
is attributed
with a level of memory. The memory is a
characteristic. It's a quality. It's an
attribute of the information. And the
way we impart this information with the
quality of good memory is through the
way we construct it. We can't just read
things or hear things and then just
immediately know. It's passing into our
brain and our brain is actively
constructing its interpretation of what
you read or heard. And so the way we
construct this is incredibly important.
If we construct it using a very flimsy
quick process, you know, just using like
paper and some tape and putting together
this box and like boom, it's done. Then
that is going to be very fragile. It's
going to degrade very quickly. That's
not strong. Whereas if we use a very
robust method with more robust uh
materials, it might be a little bit more
costly and time consuming, take some
more resources, take a bit more effort.
But if we create this box with metal
plates and weld the sides together and
and seal it off perfectly, then that is
going to last a lifetime. And the
difference between someone with a great
memory versus someone with a bad memory
is that the person with a bad memory is
used to constructing things in a very
haphazard fast way. Whereas a person
with a great memory is used to using a
robust construction method which imparts
a high stickiness of memory to this
information which leads us to naturally
hold on to and remember that memory over
time. And I think this concept is
summarized really well by this American
psychologist called Daniel Willingham
who said that memory is the residue of
thought. When we recall something, we
are not retrieving a piece of
information that's locked away in some
archive in our brain somewhere. What we
are doing is that we are remembering the
thoughts and the processes that we
experienced at the time when we engaged
with that information. So if we
construct haphazardly very quickly and
we don't give it much thought, there's
not much to remember. So a lot of my
focus when I was going through the
learning science as well as when I was
coaching for the last you know 13 plus
years was how do you construct memory to
be more robust? What are the principles
and the methods? And this is a huge
topic, like really, really huge. And so
there are so many different things that
influence our memory, but I'm going to
distill them down to what I think are
the four most universal, most applicable
that come up in the research time and
time again. And also give you some
tactics and examples within that to see
how you can apply that to your own
learning. So the first major principle
and method for improving your memory is
the spacing effect. Now, even if you
don't know a lot about learning or
learning science, uh you may have heard
about the spacing effect. This is a very
very simple concept that basically just
says that when you repeat something,
you're going to remember it for longer.
Anytime we have new information enter
into enter our brain, our brain under
goes something called knowledge decay.
And that's this line here. It's decay.
What this means is that over time, the
amount of knowledge, so knowledge here
on the y-axis, well, our ability to
recall that knowledge goes down. So in
the beginning, the first time we learn
it, the time is basically at zero. We're
going to remember everything hopefully
because we we literally just learned it.
And then after a period of time, we're
going to forget. So some studies say
that after about a week, we forget about
50% of everything that we've learned. So
half of what you learn, you forget about
a week later. Interestingly, people
overestimate that. So most people think
that they will remember about 70 or 80%
a week later, but when you objectively
test it, it usually tends to be about 30
to 50%. So we forget a lot of stuff very
quickly. And the idea with the spacing
effect is that if we hit that same
knowledge again a few days later and
then, you know, maybe a week later and
then some time again after that, each
time we hit it, this decay curve starts
flattening out. So instead of being so
steep, it looks like this and then it
looks like this. And then eventually
it's it's so flat that we're we're
basically never going to forget this.
And so the spacing effect is a really
important foundational principle to
understand because it first of all sets
up the expectation that you're not going
to be able to remember everything that
you learn just by learning it one time.
And so you should expect to need some
level of repetition. Now sometimes you
get this repetition very naturally. So
if you're learning something for work on
the job, you might naturally need to
recall and test yourself on this during
the you know during your work. But if
not you need to make sure that there is
that time carved out to allow yourself
the repetition that you need. Now the
issue here is that when you only rely on
the spacing effect or if this is the
major effect that you're using to try to
boost your memory, you're going to run
into a lot of problems. The way you
review that information makes a big
difference to how much it flattens that
curve. There are some methods that are
very passive that don't involve much
thinking. And so it doesn't contribute
much benefit. It doesn't make that
memory any stickier. And so you'll need
five or six or seven or even more
repetitions for it to be in your
long-term memory. And then usually after
that, like 2 3 months later, you'll
forget it anyway. Whereas there are
other methods that involve a bit more
deeper thinking where when you use this
method you only need like one or two
more repetitions for it to be in your
long-term memory. And so in the modern
day if you are learning a lot of stuff
and you don't have much time to learn
you're going to run into the problem of
being completely overwhelmed by the need
for repetition. And this is basically
what happened to me. I had thousands of
flash cards that I had built up and I
was spending hours and hours every
single day just getting through these
flash cards and I was forgetting faster
than my ability to review it. And so if
your entire studying methodology
revolves around the idea that you need
to repeat something, you know, five plus
times to remember it, that's not
mathematically scalable. And so while
you do need to use spacing as part of a
robust learning system, you should never
only use spacing. So even though this is
the first one that I'm covering, it's
probably, I would say, the least
impactful.
The second one makes this much more
effective. The second principle I'm
going to introduce you to is the
generation effect. The generation effect
is this finding that's been found across
decades of learning science research.
which says that when you produce your
own knowledge, you will remember it
better than if you just read it or hear
it. So actively generating knowledge is
more memorable than passively receiving
it. So that's the technical definition,
but in practice that's actually really
confusing because what does that even
mean? What does it mean to actively
generate knowledge? Some people think
that it means you have to create, you
know, synthesize this new novel piece of
information, you know, some some brand
new idea or you have to write some kind
of research dissertation about it. But
that's not the case at all. The easiest
way to understand what the generation
effect really means is that your brain
will remember things better if it needs
to do more work to get to the answer. So
I'll give you some examples of what this
actually means. So first of all just
summarize that. So your brain if it does
more work equals good. So here's an
example of some passive learning methods
and then I'll give you the more
generative
alternatives.
So one example of a passive learning
strategy might be just rereading
your notes.
So this is very passive because it
doesn't involve much thinking. The
generative version of that might be
rewriting your notes
from memory
from recall.
So you can see that this is going to
involve a little bit more work. Your
brain is going to have to do more
thinking. It takes more mental effort to
recall it and then also write it out
again. Another example might be
listening to a recording or a lecture or
a course or something. So instead of
just listening, a more generative thing
might be pausing
every two or three minutes and then
summarizing
the main points of what you just heard.
A common passive one here, uh,
highlighting highlighting the the
technique that I love to hate, very very
passive. Instead of doing passive
highlighting, a generative version of
that might be turning those things you'd
normally highlight,
turning them into practice questions or
challenges. Or another passive example
might be like copying someone's notes or
copying explanations or or writing down
what the lecturer or the instructor
says. So a generative version might be
to paraphrase,
right? write it down in your own words
or maybe even think of asking really
good critical questions about what you
are writing notes on. So you can see
there's a really clear trend here and
you can do this for basically any
technique. You just take one that's
fairly passive and unfortunately also
usually very common and you can turn
that into something that's more
generative just by thinking how do I
insert my brain in there more? How do I
involve my brain in thinking, figuring
things out, having to recall things,
piece things together to actually form
this knowledge? So, all of that thinking
is construction and that involves more
thoughts, usually more complex and
deeper thoughts and those thoughts are
usually more connected to each other.
So, they form a stronger network and all
of those things leave a longer and
stronger residue of thought, aka
stronger memory. Now, if you are trying
to train yourself to be more generative
in your learning, which you should be,
one thing that you might run into, is
knowing when it's enough. Because you
could technically just keep iterating on
this. So for example, instead of just
writing something from recall, uh maybe
you test yourself first before you do
the recall and then maybe you then
instead of just recalling it linearly,
maybe you teach it to someone and then
maybe after you teach it to someone, you
also map it out in a mind map. Uh and
then maybe you teach off of the mind
map. And then maybe you use the mind map
to generate even more questions for
yourself. And then when you answer the
questions, maybe you answer each
question in its own little mini mind
map. You know, it goes on forever. you
can sort of make it harder and harder
and harder and harder. And the rule of
thumb here is just go one step beyond
wherever you are comfortable with until
you get the result you need. You do not
need the perfect learning mechanism for
every single learning situation. If
you're at a networking event and then
you meet someone for the first time and
you just want to remember their name for
the next hour, maybe instead of just
listening to the name, you sort of
mentally test yourself. Maybe you apply
the spacing effect. you try to use that
name again in conversation a few times
that could be enough to keep it in your
memory for that particular purpose. On
the other hand, if you are a software
engineer and you're learning about a new
technology that has the potential to
completely disrupt your industry and you
know there's all sorts of implications
on the on the projects you're working on
and the problems you need to solve, you
need to learn that very very deeply. You
do not want to have to go back to the
reference material every, you know, 15
minutes because you keep forgetting the
stuff that you're learning. In fact, you
won't even be able to build real
expertise because you don't even
remember enough about what you've
learned to build on it. You'll fall into
the trap of, you know, reading a bunch
of stuff and technically understanding
it. But by the time you finished the
book, your actual expertise hasn't
increased more than the fact that you
are now aware of a few concepts and
interesting facts. And one of the worst
things that you can do when you are
training yourself to have a better
memory is reach way too far outside of
your existing current level of habits.
If you're currently very very used to
this passive learning here and most of
your learning sits within this zone,
it's going to be, you know, almost
impossible for you to try to go all the
way to, you know, something over here.
If you're if you're at level one, level
10 is going to be overwhelming. And so
if you want to actually get real
improvements in your memory on a daily
basis where every day your memory is
just getting a little bit better, then
it's imperative that you progress your
technique in accordance with the
principle of marginal gains. This is the
idea that you can just improve by 1%
every single day and the gains will
compound over time exponentially. If
you're 1% better every day, after an
entire year, you will be 37 times better
than you are today. And so, get into
this habit of when you're learning
anything new, whether it's about
improving your learning skills or any
other skill, just think about what your
current level of skill is, where you're
comfortable at, and where your current
habits sit. Then, think about where you
want to get to, and just take one step
closer to there. Take that one step, and
then stabilize until that becomes a new
habit, and then take another step. And
by doing it this way, you make sure that
you have a consistent path towards
improvement where every single step you
take is producing a meaningful realworld
benefit to your current problems and
situation. If the skill level you want
to get to with your learning is, you
know, at the very peak over here, but
we're starting right down here at the
bottom, then don't waste time trying to
jump to the top. You will jump and jump
and jump until you eventually give up.
Meanwhile, the person who is just
steadily step by step walking their way
up the mountain is going to eventually
reach the top. And even if they don't,
they are still going to be much higher
than the person who is wasting time
trying to get to the top in a single
jump. So here's what you should do if
you want to start using the generation
effect a little bit more. And you can
pair that with the spacing effect. Write
out your learning schedule from Monday
to Sunday and identify the times where
you're going to spend time to review and
space out your learning. when you're
going to do a little bit of that
repetition and then ask yourself how you
are going to review the material. Write
down the technique or the method you
normally would have used and just ask
yourself what is one step more
generative than what I was planning on
originally doing. And every two or 3
weeks do the same thing. Look at it
again. Look at the techniques you
normally would have used and you can
take an additional step. Just by doing
this very simple exercise where we pair
generation with spacing, the amount of
repetition that you will need will start
going down. Now, on the topic of
repetition, as you do this and as you
try to improve the quality of your
construction process, you're going to
find that you struggle with a few
techniques. As you try to make it more
generative, it involves more mental
effort. It's more challenging, and
you're going to need some trial and
error to get it right. And to give you
context, for me to steadily improve my
construction process to go from where I
was studying all the time to being able
to, you know, learn 100 plus pages of a
textbook with super high retention. That
took me years, like several years of
diligent, consistent hard work. But it
shouldn't take you several years because
a lot of my time was wasted on just
figuring out what was right and what was
wrong. And there also just weren't a lot
of resources then either. I mean like
this this book which is by the way
really good summarizes like 30 years of
learning science research. This was
published in 2017. By 2017 I already
read that research myself and spent the
thousands of hours to do that. And so
the reason I'm telling you this is that
if you want to save some of that trial
and error for yourself and just learn
from the mistakes that I already made,
then one thing that I'd recommend that
you check out is my free newsletter. the
emails that I send out every single week
where I've sat down and I've thought
what are the things that I wish I knew
when I was first starting and I packaged
them into these three to five minute
emails with some practical takeaways and
things for you to work on during that
week. It's pretty much like an entire
learning skills course delivered to you
through email. So if you're interested
in that, it's totally free. I'll leave a
link for you to sign up to that in the
description below. But on to the third
principle. So that was spacing and
generation. The third one is the testing
effect. The testing effect is really
self-explanatory. It says that when you
test yourself, you're going to remember
things better. But the part that I'll
add in there to make it more effective
is that the way you test yourself
matters a lot. Let's say I'm a senior
executive of a company and I need to
make some really important difficult
decisions about the the direction and
strategy of this company. And in order
to help me make this decision, I'm going
to go and learn a little bit about these
different industries. And to make sure
that I remember everything that I'm
learning so that I can really use it to
make this decision, I'm going to test my
recall on each fact through flashcards.
Do you notice something seems a little
off there? One method of testing is very
isolated, very discreet, just testing on
facts. You can see that my ability to
regurgitate facts probably isn't going
to translate that well to being able to
make these complex decisions. Well, the
same principle is true for all forms of
testing. Whenever you learn something,
you normally need to apply that
information in a certain kind of
context,
whether that's for an exam or for work.
And they're going to be multiple
different levels or depths of knowledge
that you need to apply that information
to. And so if you're only used to
testing yourself at a certain level,
then you can expect that your competence
will only increase at that level. And so
while doing practice questions and
practice exams if you're a student are
really effective way of testing
yourself, you have to check are these
questions and exams testing me at the
right level for how I need to apply this
knowledge. And this is especially
relevant if you're a professional and
you're learning not just for an exam but
also for your career where a practice
exam or the exam itself may not be
testing you in the way that you need for
your long-term career. I felt this
sharply myself where in my first few
years of university I felt like I was
really getting hang of studying. I was
getting A's and A minuses for my test. I
wasn't studying very much to get those
grades. Then when I enter into hospital,
I actually failed my first clinical
attachment and I realized that the
methods of studying that I'd been using
before were way too academic and they
didn't translate into really seeing a
patient in the real world, diagnosing
them and thinking about a management
plan. So when you test yourself, think
about what kind of thinking, what kind
of problem solving, what kind of recall
am I being forced to do right now and
does that reflect the type of recall and
thinking that I will need to do later
for you know my ultimate purpose. That's
the first thing. The second thing is
about how you actually learn from the
mistakes you make when you're testing.
So effective testing should be marked by
at least two different symptoms. First
thing is that it's actually level
matched, which is what we've just been
talking about. But the second is that it
finds and fills gaps
in your knowledge very effectively.
There's this common sentiment that I see
sometimes with the students that I work
with who will test themselves, but they
test themselves in a way that they know
they're not going to get things wrong.
They test on the subjects they're
stronger at. They ask questions that
they they're more familiar with and they
sort of consciously or subconsciously
avoid making mistakes. And I think the
idea is that there's this feeling that
if I make mistakes, it's an indication
that I'm not going to do well in my
exam. But that is the complete reverse
way of how it should be thought of. The
idea with testing is that you want to
find and fill these gaps proactively.
You want to identify these gaps so that
you don't make these same mistakes and
errors later when it really matters. And
so the faster and earlier you're able to
find these gaps, the better it's going
to be for you. And unfortunately,
most people when they learn something
for the first time have a lot of gaps.
And so if you're testing yourself in the
right way, the first time you test
yourself on something that you have
learned for the first time, you should
find truckloads of gaps and errors. And
for a beginner, this can be very
confrontational and conflicting because
it's a a hit to your confidence and it
makes you feel like, man, I've already
spent so much time learning it. How am I
going to get enough time to fill all
these gaps? But the correct perspective
is the gaps are there. The only
difference is whether you are aware of
it or not. And so if what you care about
is having real performance later when it
really matters, then it is a much better
position to be in to feel overwhelmed
but at least aware of all of your gaps
than blind to them and falsely
confident. And there are two parts to
doing this effectively. It's the finding
and the filling. These are actually two
different aspects. Finding a gap means
that the way that you test yourself is
difficult enough. Obviously, you know,
don't go overboard, but you want to
simulate real challenging scenarios that
you're going to face yourself with. And
you don't just want to test yourself in
a difficult way. You want to test
yourself at this level as early as
possible because it gives you as much
time as possible to fill all those gaps.
So, the first round of testing that you
do should involve something that is
very, very difficult. The next part is
about filling those gaps. So, you found
it, you've tested yourself in a
challenging way. How do you fill that
gap in your knowledge? On the plus side,
this can be very easy. It seems that
when you test yourself and find a gap in
your knowledge and then go to just learn
and fill that gap again using whatever
method you might have used before with a
little bit of generation applied to it.
Your brain is more effective at creating
robust knowledge than if you had never
tested yourself in the first place. So
what this means is that you could use
the exact same method to learn
something. But if you learned that after
finding out it was a gap because you
tested yourself, for some reason your
memory is just stronger. But the biggest
thing we need to avoid here are the
traps of recognition and overconfidence.
Recognition
is when you see something and you
recognize what it means. So if I
previously, you know, studied from this
textbook and I tested myself on
something in here and I, you know, got
it wrong and then I read the answer and
I recognize the answer and I think, ah,
yeah, that's right. That's the answer.
Yes, I remember now. You don't remember
now. All you do is you recognize that
that is the correct answer. So if the
answer had been completely wrong, you
might have recognized that hm that
answer doesn't make sense. it doesn't
mean that you can actually generate that
answer from scratch by yourself. And so
the gap between our ability to recognize
something and actually recall something
is huge. We can recognize the Mona Lisa
as a painting when we look at it. It
doesn't mean that we can actually
reproduce the Mona Lisa from memory. So
to avoid recognition, what you have to
do is when you test yourself and get
something wrong and then you check the
answer, don't judge your level of
confidence based on whether that answer
makes sense to you or not. Ask yourself
why. If it makes sense, was I not able
to get it right? And regardless of what
you find, make sure you test yourself on
that. again not in exactly the same way
but through some kind of variation
testing on the same part of the
knowledge and then see do you get it
right or wrong so that's recognition so
we want to make sure that we avoid
recognition the second thing we want to
avoid is this overconfidence and what
I'm referring to here is very
specifically when you test yourself on
something and you are not confident
about the answer that you've given but
then you check the answer and then you
become confident because you got it
right that is the incorrect judgment to
make. If you felt unconfident when you
were giving an answer, it means that
there's a gap. If there was no gap, you
would have felt confident giving the
answer. All it means is that either you
were lucky with the answer or you were
lucky in the way that it was tested and
you were asked that question and you
just so happened with the knowledge you
had to be able to put it together in the
right way. But if you are asked that at
a slightly harder level or a slight
variation or, you know, a little bit
more complicated, you may get it wrong.
So, as a rule of thumb, when you learn
something and you feel confident about
what you've learned, always be
skeptical. Test it. Test yourself at
enough of a difficulty to find the gaps
that you don't see. Be wary of
overconfidence.
But if you are underconfident about
something, believe it. Assume that there
truly is a gap there and don't convince
yourself to be confident of that. So,
that's the point about avoiding
overconfidence. So these are the nuances
about testing. It's not enough just to
test yourself. If you're not testing
yourself in the right way, and then when
you get feedback from your attempts,
you're not processing it in the right
way, the benefit of testing goes down
precipitously. One of the doctors I'm
training for their board certification
exams was telling me about how they
spend hours and hours every single week
just going through this question bank.
And they've gone through thousands of
questions and every time they sit down,
they're getting through like 50 to 100
different questions. And after I taught
them about these nuances, they slowed
that right down so that each session
instead of doing 50, they're only doing
five to 10. And so even though they were
actually doing less questions, they
started getting more benefit from each
study session because the quality of
learning they're extracting per question
is so much higher. Before they would get
questions wrong and then be tested on
very similar questions later and then
get them wrong again and then it would
take a lot of time to fill those gaps.
Whereas now when they get a question
wrong, they're never getting that
question wrong later. And that change
came from mostly just avoiding
recognition and overconfidence. So that
was the third principle, the testing
effect. So far, we've got spacing,
generation, and testing. And you can see
how they can all come together. When you
do your spacing sessions, each time you
repeat it, this is a great opportunity
to test yourself. When you're testing
yourself, you want to apply these
principles. And when you're filling the
gaps, you want to make sure you
generative in the way that you think
about it. When you learn something for
the first time, you want to make sure
that you are doing enough generation.
And so these principles apply
universally for every type of learning
scenario that you find yourself in. But
there is one thing missing. Been
watching my videos for a long time, you
might guess what this last one is.
Because personally, I think this is
probably the most important out of them
all. And this is higher order thinking.
Higher order thinking and higher order
learning is a term that's used for the
specific processes and types of thinking
that create long lasting knowledge and
deep understanding of information. And
amazingly, all of these methods share
the same commonality that they look at
pieces of information as part of a wider
network. And an easy way to understand
what higher order of thinking really
means is to think about information that
feels relevant versus information that
feels irrelevant. Imagine being back in
school learning a topic that you really
don't care about. You're not interested.
Your teacher is boring and you're just
sitting there learning it basically
because you just need to pass some exam.
That topic feels more difficult to learn
because it's so irrelevant. Whereas
think about something that you know a
lot about. It could be something
academic. It could be something for your
work. It could be a favorite hobby or a
book or a movie. And I bet if I tell you
a fact, a new fact about that topic, you
would be able to think about it,
understand the implication of it, how it
affects everything else around it, and
probably remember that new fact forever.
You don't need any spacing. You don't
need any flashcards. You don't need to
write any notes. It's almost like this
network of knowledge just comes out to
grab this new piece of information and
it's consolidated into your memory
immediately. The reason that happens is
that when a topic is irrelevant. We
can't connect it to anything else. So
our brain is finding it very difficult
to actually have thoughts about it. And
so even if you want to build really
robust memory, you're not going to be
able to because you don't have the
resources there. you don't have enough
thoughts to layer on top and give this
that good memory attribute. On the other
hand, for the topic you know a lot
about, you have this wealth of
information. And as soon as this
information comes in, there are so many
different angles that you can think
from. And so this information doesn't
exist in isolation. It exists in the
context of everything else you know
around that information. And being able
to think about new information in a way
that fits it into a network is what
higher order thinking and higher order
learning are all about. And the reason I
said that this is so important is
because when you use higher order
learning, you're able to increase your
memory drastically. This is the secret
to how instead of having a knowledge
decay curve that looks like this one,
you're able to learn something for the
first time and immediately have a decay
curve that looks like this. It's almost
flat. And yes, you still need to repeat
it and test yourself at some point
later, but you may not need to test
yourself for another month. And even
then, your attention is 80 90%. And
learning to think at this higher order
translates directly to how well you can
use the generation effect and the
testing effect. Higher order thinking
naturally involves more mental effort.
To do higher order thinking correctly,
you have to generate more. And being
familiar with higher order learning
allows you to test yourself at the
higher orders, which is usually the
level you need to get to to solve
complex problems or have deep
discussions and write thought-provoking
essays or to make highstakes complicated
decisions. Interestingly, it's also the
inability of AI to do higher order
thinking and reasoning that makes it so
bad in scenarios that are really complex
where there are a lot of different
things interacting with each other and
the situation is nuanced. So, here are
some ways that you can train yourself to
be better at this higher order of
thinking and higher order learning. Uh,
and now again, this is a huge topic and
you know, training this is kind of like
my main thing. So, I'm going to simplify
it for you in this video. So first of
all, higher order thinking is all about
being integrated in your thinking.
Thinking about the big picture, creating
a network of information rather than so
this is what you want to do. And what
you don't want to do is you don't want
to be isolated. You don't want to think
about things fact by fact or concept by
concept. And you definitely don't want
to be stuck in the trap of trying to
memorize information through just
repetition. Remember, you don't have to
memorize things because if you apply
these principles, you naturally
construct a better memory, which means
that your attention is better and you
will just automatically remember it. If
you are actively trying to memorize what
you are learning through just reading it
again and again, that is like a super
super red flag. That flag is neon red.
There are times when you do have to
memorize things, but it is the minority
of your learning and usually only after
all of these other things have failed.
So what are some techniques that you can
use to get better at this higher order
of thinking and learning? The first and
maybe simplest one that you can apply is
creating analogies. Try to create
analogies often when you're learning. Go
through a concept, pause, make an
analogy. You can even make analogies of
your analogy. So have multiple analogies
and then bring them together to create
one mega analogy. The reason this works
is that creating an analogy forces you
to think about what you're learning in
the big picture. It pulls you out from
just thinking about each piece of
information as fact by fact by fact and
it asks yourself how does it all come
together? How can I tell a story with
this? Another method that you can use is
teaching. Teaching is also a method of
testing that you can utilize. But
importantly, the way you teach matters.
If you just ramble on this endless
internal monologue and the thoughts are
very disorganized, that's not going to
be very easy to follow and you're not
having to use your higher order thinking
skills to organize it. So try to teach
it in the most intuitive, most logical
way possible. That is the easiest to
follow. Some people say teach it to a
10-year-old. This framing is great
because it forces you to think about it
simply, but you don't have to just do at
a 10-year-old. If you teach at a
10-year-old, sometimes you miss out on
that really detailed technical
information that you want to test
yourself on. The point is that you want
to use teaching as an opportunity to
organize all of your thoughts and think
about which concept or groups of
concepts should I talk about first? What
makes the most sense for me to start my
teaching with? You can see that in order
for you to make that decision and make
that judgment, you have to be comparing
each concept against every other
concept. It's a very integrated network
style of thinking and of course that
involves a lot of mental effort. That's
a lot of generation. There's a lot of
thoughts. That's a lot of residue.
Another method that you can use is mind
mapping
or any form of nonlinear notetaking. The
reason this is good is because it
visualizes the connections that you're
making instead of writing things out
linearly sentence by sentence which
makes it easy to be locked into this one
fact at a time kind of perspective.
Creating a nicely connected mind map
forces you to take a step back and look
at the big picture. But at the end of
the day, whether you're using analogies
or teaching or mind maps, these are just
methods that try to get you to think in
a certain way. Remember, it's higher
order thinking. It's not higher order
drawing a mind map. It doesn't matter
whether you create an analogy or teach
or make a mind map if you're not
activating the right thinking process.
And an effective way of training
yourself to get good at this thinking
process is as you are trying to use
these techniques and doing any other
type of learning after every session ask
yourself these three questions. Question
number one, how often am I trying to
connect what I'm learning to the big
picture? How often am I zooming out and
thinking about the overall purpose of
what I'm learning? The answer to this
question should be almost constantly.
There should not be more than two or
three minutes at a time where you are
not coming back to the big picture. And
yes, that is very challenging for people
who have not experimented with higher
order learning before or don't have
those habits. But remember what I said
about the marginal gains. If you are
down here in terms of your current level
of habits, do not try to get to a
constant level of thinking immediately,
just do it a little bit more. Zoom out.
Look at the big picture once every 10,
15 minutes. And once you're comfortable
with that, do it every 5 to 10 minutes.
Just take one step in the right
direction. So that's the first question.
The second question to ask yourself is,
how often do I actively try to simplify
what I'm learning? Simplifying is all
about trying to understand something in
such a way that you don't need to
memorize it, making something feel more
intuitive and more obvious. When you do
this, it forces you to think about the
information in relation to what you are
already familiar with. Creating
analogies is an example of trying to
simplify information. When you ask
yourself this question, the answer
should be after every concept, after
each block of new information, you
should be pausing. You should be
thinking about what you've just learned
to simplify it and apply that thinking
to it and create a robust memory. You
don't want to end up with 14 pieces of
new information that you now need to
apply all of this thinking for
simultaneously. That's going to be way
too overwhelming. And the third question
is, how long do I delay
creating relationships? What this means
is how long do you wait after having
heard something or reading something
before you think about how it compares
or connects with something else? Do you
read sentence after sentence after
sentence after sentence just trying to
understand everything that you have read
and then only after one or two pages go
and think about okay how does it all
relate to each other? How are they
similar? How are they different? How can
I simplify and group these things
together? If you're doing that, that's
way too delayed. It's going to be very,
very hard for you to make sense of that
because there are so many connections
and so many possible relationships,
you're going to be spending hours just
working them out. It is much more
efficient to think like an expert where
for each new piece of information,
you're immediately trying to think
about, okay, so how does that compare to
what I already know? How does that
compare with what I've just learned? How
can I simplify and group that
information? And this is actually the
part of higher order thinking that most
beginners trip up with the most and they
get stuck on. They're so used to
consuming and consuming information
assuming that just understanding means
that you're going to remember that they
feel very very uncomfortable with
ignoring how deeply you've understood it
and just going straight to creating
these relationships and thinking about
it like a network. But the reality is
that when you think about it in a
network, it actually helps you to
understand. Comparing something that you
don't fully understand with what you
already know and the other things that
you've learned deepens your
understanding of it. On the other hand,
when you just try to understand each
thing in isolation, all it does is it
increases the risk that you've
misunderstood it. And so when you ask
yourself, how long do I wait? How long
do I delay before I start forming these
relationships? It should be as close to
zero as possible. And again, this is
challenging, so take it step by step.
And so these four principles, spacing,
generation, testing, and higher order
thinking, if you're able to apply these
principles in the way that you learn, I
can guarantee you that your memory will
shoot up. Your memory may not be
exceptional overnight, but if you
continue to take one step at a time,
just getting 1% better every day, you
will improve. That's how I improved and
that's how all my students and coaching
clients improve. Now, if you like this
video and you want to see how all of
this maybe fits in with the bigger
picture of learning and all the other
techniques you might be using, then you
