Outlines
🧠 Inversion and First Principles Thinking
The first paragraph introduces the concept of 'three what-ifs' as a mental model for decision-making and problem-solving, inspired by Shane Parrish's book 'The Great Mental Models'. The 'I' in what-ifs stands for inversion, which is a technique of considering the opposite to solve a problem. For instance, instead of asking how to make a good video, one should first consider how to make a bad one and then invert those ideas to derive a good solution. The 'F' stands for first principles thinking, exemplified by Elon Musk's approach to rocket manufacturing. Musk questioned the traditional high cost of rockets by breaking down their components and finding cheaper alternatives, leading to the creation of SpaceX. This method encourages questioning existing solutions and understanding the fundamental reasons behind them, which can lead to innovative solutions.
🔮 Second Order Thinking and Its Impact
The second paragraph delves into the 'S' in what-ifs, which stands for second order thinking. This concept is about considering the consequences of consequences, or the indirect effects of actions. The historical example of post-World War I treaties with Germany illustrates how failing to consider second order effects can lead to unintended and disastrous outcomes, such as the rise of fascism and World War II. The paragraph advises applying second order thinking to foresee potential reactions to decisions, using the example of a CEO requiring employees to return to the office, which could lead to a backlash and negatively impact company culture. The summary also mentions the book 'So Good They Can't Ignore You' and 'Drive', suggesting these resources for understanding rewarding work components. The paragraph concludes by recommending Shane Parrish's book and offering a one-page PDF summary for those interested.

i recently read the great mental models
by shane parrish
author shane parish says in life and
business
the person with the fewest blind spots
wins
after reading the great mental models
i've started considering what i call the
three what-ifs
while making big decisions and solving
hard problems
the ifs and what-ifs are three thinking
methods
better known as mental models that help
reveal blind spots and uncover creative
solutions to problems
the i and what ifs stands for inversion
when you're having trouble solving a
problem try solving the
opposite problem first instead of asking
how can i make a really good video
ask how can i make a really bad video
instead of asking how can i be more
productive today
ask how can i be as unproductive as
possible today
once you've generated a list of ideas
invert them
when i consider how to make a really bad
video i think of using powerpoint slides
with no images or examples
i think of using a monotone voice that
will put my audience to sleep
and i think of making the video much
longer than it needs to be
when i invert those ideas i think of
making a video with minimal text and
plenty of colorful examples
i think of using lots of vocal variety
and making the video
as short as possible when i wonder
how i can be as unproductive as possible
today i think of sleeping till noon
eating a big stack of pancakes for
breakfast that leaves me feeling
lethargic
and responding to emails all day by
inverting those ideas
i can plan a highly productive day that
is i'll wake up at 5am
fast till noon so i can focus better and
only check my email
after completing my most important task
for the day
solving opposite problems or
deliberately coming up with bad ideas
is fun and it typically gets your
creative juices going
plus bad ideas are surprisingly valuable
once you invert them
the next time you feel pressured to come
up with a brilliant solution
use the mental model of inversion as
shane pair says
avoiding stupidity is easier than
seeking brilliance
the f in what-ifs stands for first
principles thinking
elon musk had a problem he wanted to go
to mars but acquiring a rocket to get to
mars
was simply too expensive so musk asked
himself
what is a rocket made of well aerospace
grade aluminum alloys
plus some titanium copper and carbon
fiber
then he wondered what is the value of
those materials on the commodity market
after some research musk discovered that
the materials made up roughly two
percent of a typical rocket price
after a simple examination of the
underlying components musk saw an
opportunity
to create a better solution to his
rocket to mars problem
years later spacex was born most people
assume
existing solutions exist for a good
reason and never question them
first principle thinkers don't take
existing solutions at face value
they drill down to understand why a
solution works
a few decades ago a group of food
researchers liked the taste of meat
but didn't like the idea of harming
animals to get their meat
after some first principles thinking
they realized that the fundamental
components of great tasting meat
was simply a collection of amino acids
and sugars
no animal necessary this discovery
led to the creation of the fake meat
industry
now it would be exhausting to solve
every problem with first principles
thinking
it's typically okay to go with an
existing solution to most problems
but when faced with a highly
consequential decision or problem
like what career to choose or what
business to start don't
simply do what other people are doing
instead
put your first principles cap on and
start drilling down to understand the
fundamental components of existing
solutions
for example if you're looking to make a
career change don't assume that you'll
like a career just because your friend
does
the components of a career that make
your friend happy might make you
miserable
do some first principles thinking by
understanding your friend's day-to-day
experience at work
to see the fundamental components of his
career then identify core components of
rewarding work you've done in the past
and search for core components of work
satisfaction in books like
so good they can't ignore you or drive a
link to both those book summaries
in the description below if the career
you're examining
looks like a good fit great if not look
elsewhere or use the first principles
you discovered
to create a new career the next time
you're faced with a highly consequential
decision or problem
use first principles thinking to examine
existing solutions
test assumptions and understand the
fundamental components that make a
solution work
then either go with that solution or use
those first principles to come up with a
better solution
the s in whatifs stands for second order
thinking
after world war one the british and
french forced germany to disarm
give up territory and pay reparations
that would be worth roughly 500 billion
dollars today
the british and french got what they
wanted a weak germany
that could not wage war again or so they
thought
the british french and other allied
powers failed to consider the second
order effect
of their actions namely feeling the rise
of fascism in germany
that would lead to far more destruction
in world war ii
second order thinking gets you to think
beyond the outcome you're going for
and consider the reaction to that
outcome it's important to incorporate
second order thinking in your decisions
to avoid disastrous unintended
consequences that come from second order
effects
if you're a ceo of a company and you
demand that everyone comes back to your
office
after a year from working at home thanks
to covid you might get what you want
namely improving the culture with
everyone back together but your actions
might have the second order effect of
getting people to realize
how much they hate commuting to work and
miss the convenience of working from
home
those people might lead the company
which could ultimately destroy the
culture
before implementing any solution or
making any important decision
do some second order thinking by taking
a minute to simulate
what the reaction to your solution or
decision might lead to
in the end if you're struggling with a
problem or need to make an important
decision
consider the three what-ifs inversion
solve the opposite problem or consider
how you'd make a terrible decision
then invert your ideas and see what
valuable insights you discover
first principles thinking examine the
foundational components of existing
solutions
and test them adopt a solution with
sound fundamentals
or use the first principles you
uncovered to develop a better solution
in second order thinking simulate
reactions to your solution or decision
to prevent your solution or decision
from backfiring
that was the core message that i
gathered from the great mental models by
shane parrish
this is a quick and fascinating read
with many helpful thinking tools
i highly recommend it if you would like
