We think about and make decisions every day; this is how we
have survived. Historically speaking, those who were quickest to act survived,
and those who were silent and took time to ponder future outcomes were probably
eaten by some wild animal. This is why we have involuntary reactions. However, presently
we have the luxury, and sometimes the misfortune, of being able to have, for
the most part, as much time to postulate the future as we would like.
Enter survivorship
bias.
Survivorship bias is essentially humans’ tendency to
over-estimate our chances of success because only success is advertised. Rolf
Dobelli in The
Art of Thinking Clearly does a very good job explaining this phenomenon;
the book is worth a read. The combination of our ability/fortune to fanaticize
about future outcomes and our systematic tendency to overestimate our chances
of success leads to serious miscalculations. We observe the sea of randomness
present in our everyday lives; take out little bits and pieces that we find worthy
enough to serve as a good defense of our preconceived notion of our
high-probability of future success.
We do not see the tens of thousands of athletes who don’t go
pro, we do not see the vast majority of musicians who never get a record label;
we are constantly deceived by those on the big screen who have “made it.” An
additional catalyst to these cognitive miscalculations is that we think that if
we do what those who are famous did, or at least a derivative of it, our
chances of success go even higher. These thoughts are of course additional
reorganization of randomness into a beautifully laid out map to success: this
is a sham. Instead of gathering facts to form a theory we form a theory and
then gather facts to support it; this leads to further inaccuracies in the
decision making process.
What I think we forget is just how little is in our control.
If we were born a thousand different times in a thousand different homes we
would have a thousand different parents with a thousand different value sets. It
is simply too convenient that we were born to parents or guardians that had the
“ideal” value-set or “perfect” belief-system. As a matter of fact, I believe
that those “core-values” and “core-beliefs” are the things that we should be
most skeptical of. This is because the younger we were when an idea or belief is
introduced to us, the higher our bias to believe it is: the less it is in our
control. This goes back to the classic argument that a Hindu, if born in a
Jewish home, would probably end up being Jewish. There is just too much that is
out of her control, too may occurrences and teachings that will prevent her from
stumbling her way to a different religion.
Objective evaluation of beliefs and value sets is becoming
increasingly important to me on my quest towards procuring wisdom. To quote
Taleb for a second time:
“Probability is not a
mere computation of odds on the dice or more complicated variants; it is the
acceptance of the lack of certainty in our knowledge and the development of
methods for dealing with our ignorance.”
