9 Mental Models You Can Use to Think Like a Genius
Summary
TLDRThis video introduces nine mental models that enhance problem-solving and broaden one's perspective. It explains that mental models are simplified representations of complex realities, using examples like how different professionals perceive a forest. Key models discussed include 'Map is not Territory,' 'Circle of Competence,' 'First and Second Order Thinking,' 'Probabilistic Thinking,' 'Inversion,' 'Occam's Razor,' 'Hanlon's Razor,' 'Reciprocity,' and 'Activation Energy.' These models encourage understanding the limitations of our knowledge, making informed decisions, and considering the broader implications of actions.
Takeaways
- 🧠 Mental models are representations of how the world works, helping us understand complexity with limited knowledge.
- 🌲 Different individuals with diverse expertise perceive and simplify complex situations like a forest in unique ways.
- 🤔 Mental models allow us to learn fundamental concepts from other disciplines, providing a larger 'toolbox' for problem-solving and reducing blind spots.
- 🗺️ 'Map is not the territory' teaches us that representations, like maps, are not the actual reality and have their limitations.
- 🛡️ 'Circle of competence' is the knowledge area where we have expertise; decisions within this circle can be made confidently.
- 🔄 'Second order thinking' involves considering not just the immediate consequences of actions, but also the consequences of those consequences.
- 🎯 'Probabilistic thinking' involves estimating the likelihood of outcomes, helping us perceive the world in shades of gray rather than black and white.
- 🔄 'Inversion' is a thinking tool that starts from the opposite end of the desired outcome, focusing on avoiding failure rather than achieving success.
- 🔎 'Occam's razor' suggests that the simplest explanation is often the correct one, preferring straightforward solutions over complex ones.
- 🤝 'Reciprocity' suggests that actions often prompt equal and opposite reactions, encouraging us to treat others as we wish to be treated.
- 🚀 'Activation energy' from chemistry can be applied to life, where catalysts like coffee or inspiration can lower the energy needed to start tasks.
Q & A
What is a mental model?
-A mental model is a representation of how the world works, used to simplify the innate complexity of experiences and aid in understanding things that are not fully comprehensible.
How do different people perceive the same situation based on their mental models?
-Different people perceive the same situation differently based on their mental models because each person's understanding and focus are shaped by their unique experiences and knowledge, leading to varied interpretations and priorities.
Why is it important to use multiple mental models?
-Using multiple mental models is important because it provides a broader toolbox for understanding and decision-making, reducing blind spots and allowing individuals to see the world through various lenses, thus enhancing comprehensive understanding.
What does the mental model 'map is not the territory' teach us?
-The mental model 'map is not the territory' teaches us that representations of reality, like maps, are not the actual reality itself. They are reductions and simplifications, hence imperfect, and we should not rely solely on them for decision-making.
Can you explain the concept of 'circle of competence'?
-The 'circle of competence' refers to the areas of knowledge or skills where an individual has developed expertise through experience and study. Decisions made within this circle can be made with confidence, while those outside may require consulting an expert.
What is second order thinking and why is it important?
-Second order thinking involves considering not only the immediate consequences of actions but also the consequences of those consequences. It is important because it helps in understanding the potential long-term effects of decisions and avoiding unintended negative outcomes.
How can probabilistic thinking help us in decision-making?
-Probabilistic thinking helps us estimate the likelihood of outcomes using mathematical and logical tools. It allows us to assign probability estimates to events rather than viewing them as binary possibilities, leading to more nuanced and accurate decision-making.
What does Occam's razor suggest when evaluating explanations?
-Occam's razor suggests that the simplest explanation with the fewest assumptions is more likely to be true than a complex one. It encourages us to prefer straightforward explanations over convoluted ones when problem-solving or making decisions.
How does Hanlon's razor differ from Occam's razor?
-While Occam's razor focuses on preferring simple explanations in problem-solving, Hanlon's razor advises against attributing actions to malicious intent when they can be explained by incompetence or error. It suggests that misunderstandings or mistakes are more likely than deliberate harm.
What is the principle of reciprocation in the context of mental models?
-The principle of reciprocation suggests that actions tend to be met with similar responses. If you treat others with kindness, they are likely to reciprocate, and the same applies to negative treatment. It encourages a considerate approach to interactions.
How can the concept of activation energy from chemistry be applied to personal productivity?
-The concept of activation energy can be applied to personal productivity by identifying small catalysts that lower the energy required to start tasks. For example, a cup of coffee or a motivational quote can help overcome the initial resistance to starting a difficult project.

🧠 Understanding Mental Models
This paragraph introduces the concept of mental models as representations of how the world works, which help us navigate the complexities of life. It explains that different individuals, such as an environmentalist, a botanist, and a business person, will focus on different aspects of the same situation due to their unique mental models. The paragraph emphasizes the importance of integrating various mental models to reduce blind spots and improve decision-making. It also introduces the first mental model, 'Map is not the Territory,' highlighting the imperfections in our representations of reality and the need to understand the actual situation before making decisions.
📊 Developing Expertise and Thinking Probabilistically
The second paragraph delves into the 'Circle of Competence' model, which encourages individuals to recognize their areas of expertise and consult experts when decisions fall outside their knowledge base. It also discusses 'Probabilistic Thinking,' urging the estimation of likelihoods for outcomes rather than binary judgments. The 'Inversion' model is introduced as a tool for identifying obstacles to success by considering what could cause failure. The paragraph concludes with 'Occam's Razor,' advocating for simplicity in explanations and decisions, and 'Hanlon's Razor,' which advises against attributing malicious intent to actions that could be explained by incompetence.
🔄 Reciprocity, Activation Energy, and Taking Action
The final paragraph discusses the 'Reciprocity' model, which suggests that actions often prompt equal and opposite reactions, encouraging kindness to foster positive relationships. 'Activation Energy' is explained using a chemistry analogy, highlighting the need to lower the barriers to action, such as starting a project, by identifying and addressing the factors that increase the required energy. The paragraph concludes by encouraging viewers to subscribe to a weekly newsletter for more content on mental models.

in this video you'll learn nine
different mental models that you can use
to solve difficult problems see the
world in ways that no one else could
even fathom and all around just improve
how you think if you're wondering what a
mental model is it's simply a
representation of how the world works we
operate in a very complex world and it's
impossible to truly understand all the
different intricacies of everything that
we experience so in order to help us we
use these different models in ideas that
we do understand to Aid Us in learning
about the things that we don't
understand here's a quick example let's
say an environmentalist of botanist and
a business person walk into a forest
they're all going to focus on different
things the environmentalists May focus
on the impact of climate change the
business person is probably going to
look at the forest and see the immense
value of the land and the botanist is
going to focus on the ecosystem each
person essentially is simplifying the
innate complexity of the forest into
something that that they could
understand with the limited knowledge
that they have while doing this isn't
necessarily bad what they see is
entirely limited to what they know and
therefore they can't see the full scope
of the forest so one thing they may end
up doing is sharing their specialized
knowledge with each other this creates a
scenario where each person develops a
much more well-rounded understanding of
the forest this is exactly what you do
with mental models you'll learn the
fundamental concepts of other
disciplines to help give you a bigger
toolbox if you will to sort of see the
world through the more models you have
the more lenses you can use while you
look at the world and therefore the
fewer blind spots that you end up having
so now that you understand what a mental
model is in the importance of using all
of these different models throughout
your life let's learn what some of those
models actually are and how you can use
them
one of the most important mental models
to learn is map is not the territory
this model teaches that the
representation of reality is not actual
reality even the best maps are imperfect
because they are naturally reductions of
what they represent if a map were to
represent the territory with perfect
Fidelity it would no longer be a
reduction of the thing it would just be
the thing like like imagine trying to
navigate New York with a map the size of
New York in your pocket there are just
so many obvious reasons why that won't
work at a more practical level the graph
or the spreadsheet of the financials of
the company isn't actually the
financials of the company so it doesn't
accurately represent the real important
numbers in the dollars in your bank
account the information about a project
from your direct report isn't the actual
project so before making decisions based
on these assumptions and maps and
reports and summaries you have to ensure
that you understand 100 percent that
there production of the thing is not the
thing so make sure you get familiar with
the actual territory before you make an
important decision and not just go based
on whatever the map is saying
circle of competence is simple each one
of us through our experience and our
study has built up useful knowledge on
different areas of the world some of
those areas are inside of our circle of
competence and these are the things that
we understand well if you work as a
marketing director marketing is probably
within your circle of competence product
might be around the edges and
Engineering is well outside of your
circle of competence so now when you
make a decision you can evaluate where
the scope of that decision lies relative
to your circle of competence if it falls
inside of it you can make the decision
with a confidence knowing that you have
the expertise to make the decision if
the decision Falls outside of the scope
of your circle of competence that's when
you can consult an expert whose circle
of competence contains that decision Tom
Watson the founder of IBM put it best
when he said I'm no genius I'm smart in
spots and I stay around those spots we
should all aim to do the same
almost everyone can anticipate the
immediate results of their actions this
type of first order thinking is easy and
safe but it's also a way to ensure that
you get the same results that everyone
else does second order thinking is
thinking further ahead and thinking
holistically it not only requires us to
consider our actions and their immediate
consequences but also the consequences
of those consequences there's a really
famous story about this that is now
called the Cobra effect and it's about
in the 1900s British Colonials ruled
India at the time but there was a
massive Cobra problem they were just
everywhere what the government did was
they decided to pay citizens to kill
snakes so citizens would kill the snakes
and then bring them to the government
and they get paid for kind of like a
bounty system what ended up happening
was the citizens just started breeding
snakes so they could kill them to make
more money once the government found out
about this and ended the Bounty program
the citizens now had no need for all
these newborn snakes so they just let
them loose in the street making the
Cobra problem even worse off than it it
was before this story illustrates the
perfect example of what happens when
someone doesn't consider the second
order effects of their decisions you
might be wondering where I'm getting
this content from and it's from our
actual books we've written three books
on mental models and how to use them in
your life we've also written hundreds of
blog posts on our site fs.blog so if you
want to learn more about any of these
and go into more detail you can visit

probabilistic thinking is essentially
trying to estimate using some tools of
math and Logic the likelihood of any
specific outcome happening the world as
complex as it is is very rarely black
and white so instead of deciding things
as either happening or not happening
probabilistic thinking encourages us to
assign a probability estimate to that
thing happening to get a more accurate
result as a simple example let's say you
read a headline in a local paper that
says car break-ins On The Rise now
without thinking probabilistically you
probably might start freaking out about
leaving your car parked on the side of
the street but using probabilistic
thinking you can add a little bit more
context to this for example let's say
you know that violent crime has been
declining to its lowest rates in decades
your city is now safer than it has been
ever let's also say that the chance of
your car getting broken into last year
was one in ten thousand or point zero
one percent the article states with
accuracy probably that this type of
crime has doubled it it is now two in
ten thousand or point zero two percent
now is that worth being terribly worried
about
probably not so the prior information
here is key when we Factor it in we
realize that our safety isn't really
being compromised
inversion is a powerful tool to improve
your thinking because it helps you
identify and remove different obstacles
to success as a thinking tool it means
approaching a situation from the
opposite end of the natural starting
point when most of us start a new
project we'd like to think about what
success would look like and then we set
the goals and priorities around getting
there using inversion though you think
about what failure it would look like
and what might cause that then you set
goals and priorities to ensure you avoid
whatever it is that might cause that
failure instead of thinking about
success and aiming for whatever that
looks like you think about failure and
make sure you stay away from whatever
that looks like Charlie Munger has
famously said all I want to know is
where I'm going to die so I'll never go
there
simpler explanations are more likely to
be true than complicated ones this is
the essence of Occam's razor a classic
principle of logic and problem solving
instead of wasting your time trying to
disprove very complex and intertwined
scenarios you can make decisions more
confidently by basing them on the
explanation that has the fewest moving
Parts a simple example of Occam's razor
is used to find the truth among
conspiracy theories most conspiracy
theories have many complicated and
interwoven threads that seemingly paint
a bigger picture but for conspiracy
theory to be true all of those
individual threads need to be proven 100
accurate that's really hard to do it's
much simpler and much more rational
honestly to assume the logical
explanation because it has fewer
dependencies for example the Titanic
hitting an iceberg and sinking is pretty
cut and dry there's not many
dependencies on the other hand a lot of
things had to have happened for the
Freemasons to cause sinking of the
Titanic which is believed by some
doctors often look for the simplest
solution to an ailment and scientists
usually start with the Least Complicated
hypothesis to disprove and then they go
from there
another helpful razor is hanlon's Razor
this model says that we should not
attribute to maliciousness that which is
easily explained by incompetence
essentially just because someone does
something that makes you mad or upsets
you doesn't mean they're out to get you
like we so often believe it's far more
likely that they are just ignorant of
something or something else is going on
in their life for example if a good
friend hasn't responded to your messages
lately using hanlon's razor we can
assume it's far more likely that they
are busy with work or something personal
came up than it is that they no longer
want to be your friend
reciprocity or the principle of
reciprocation if we want to get super
fancy it states that for every action
there is an equal and opposite reaction
in life the same is true if you treat
someone with kindness odds are they are
going to reciprocate kindness back to
you but the opposite is also true if you
treat someone poorly you can't be
surprised when they do the same to you
reciprocity prompts us to rewrite the
Golden Rule a little bit saying do unto
others knowing that something will be
done unto you
activation energy is a model from
chemistry and it tells us that a
chemical reaction needs a certain amount
of energy before it can begin working
one way to increase energy in a chemical
reaction is with a catalyst this is
something that can be added to a
reaction to lower the activation energy
that is required using this practically
in our lives we can identify some
catalysts like coffee or inspiration
even that make doing hard work or a big
project easier writing along paper is a
really difficult task and takes a lot of
activation energy to start and get going
if you drink coffee you can help lower
that activation energy and get you going
a lot quicker when someone you know is
struggling to get started on a project
or finish a project try to identify
what's causing so much activation energy
to be required and see if you can
somehow lower that threshold if you
