👥 Herding Behavior and Its Impact
This paragraph delves into the concept of herding behavior, where individuals make decisions based on the actions of others rather than their own information. It uses a quote from John Steinbeck's 'The Grapes of Wrath' to illustrate the human tendency to seek safety in numbers during uncertain times. The paragraph explains how this behavior can lead to a distorted signal chain, as seen in the example of customers choosing a restaurant based on the crowd rather than their own judgment. It also touches on the potential negative consequences of herding, such as the misinformation cascades that can occur, and uses the 2008 financial crisis as an example of how herding behavior might have influenced decision-making, leading to a widespread economic collapse.

Transcripts
thus it might be that one family camped
near a spring and another camped for the
spring and for company and a third
because two families had pioneered the
place and found it good and when the Sun
went down perhaps 20 families and 20
cars were there this quote from John
Steinbeck's classic The Grapes of Wrath
paints a powerful reality about human
nature it depicts humans as the social
animals that we are reminding us that in
times of uncertainty people are afraid
and when we're afraid we rely upon the
herd to guide us sure the crowds
guidance can be a useful crutch to lean
upon but what happens when we use it too
often when we're just lazy the concept
we're teasing out here is known as
herding behavior and we can define it as
people doing what others do instead of
using their own information to make
decisions this happens often we see a
large number of people acting in the
same way and we think there is no way
that they could all be wrong they must
know something that we don't we start to
base our decisions off of the assumption
that everyone else has done their
research or knows something that we
don't know but that's not always the
case consider the following example
offered by Robert Shiller an economist
at Yale suppose two restaurants open
next door to each other restaurant a and
restaurant be the very first customer
sees two empty restaurants and must
choose which one to eat at based only on
their appearance let's say she chooses
restaurant a the second customer sees
one person eating at restaurant a and an
empty restaurant B she makes her choice
based on two things first the appearance
of each restaurant that's her own
information and secondly the fact that
the first customer chose restaurant a
that's external information if the
second customer chooses to go to
restaurant a then the third customer
will see two people eating at restaurant
a and an empty restaurant B I think you
see where this is going as people
continue to join
the crowd they prompt others to do the
same eventually each customer might end
up at restaurant a which could actually
be the poorer restaurant what's happened
is people have ignored their own
information and that creates a distorted
signal chain we think that everyone has
made an informed decision and that
decision appears to have value but in
reality everyone has based their
decisions on the decisions made by
others and because of this our decision
contains no real valuable information
these chains of behavior are sometimes
called informational Cascades and they
help us explain everything from standard
conformity to fads and booms and crashes
speaking of booms and crashes you might
remember the financial crisis of 2008
while an event as cataclysmic and
complex as that cannot be explained by
one behavioral failure
research suggests that hurting behavior
may have played a role in
decision-making by investment managers
investors concerned with their own
reputation have shown to mimic the
investment decisions of other managers
ignoring their own private information
it's worth returning to the idea that in
times of uncertainty people are afraid
and when we're afraid we rely upon the
herd to guide us as the financial world
collapsed in 2008 and uncertainty loomed
above us all there's no question that
our herd mentality kicked in and it
probably played a role in our
decision-making whether or not we're
aware of it our reliance upon the herd
plants the seeds which will influence
the stores we shop at the restaurants we
try out and even the universities we
choose to attend the solution is not to
avoid all external information rather
the idea is to become more aware of the
information we're using to make
decisions especially when we're
observing what other people are doing
the herd is not synonymous with bad
however our over-reliance on the herd
prompts ignorance and distorts the
information we use to make decisions
