What is Confirmation
Bias?
By Shahram Heshmat, Ph.D.
2015
[1]
Imagine that you have tried to reach a friend with whom you have an ambivalent
1 relationship by phone or email, leaving messages, yet receiving no call in return. In a situation like this, it is easy
to
jump to conclusions in an intuitive
2 manner that your friend wants to avoid you. The danger, of course, is that you
leave
this
belief
unchecked
and
start
to
act as
though
it
were
true.
Confirmation
bias
occurs
from
the
direct influence
of desire on beliefs. When people would like a certain idea
or
concept
to
be
true,
they
end
up
believing
it
to be
true. They are motivated
by
wishful
thinking. This

error leads
the
individual
to
stop
gathering
information
when
the
evidence
gathered
so
far confirms
the
views or
prejudices
one
would
like
to
be
true.
Once
we
have
formed
a
view,
we
embrace
information
that
confirms
that
view
while
ignoring,
or rejecting, information that casts doubt on it. Confirmation bias suggests that we don’t perceive
3 circumstances objectively.
4 We pick
out
those
bits
of
data
that
make
us
feel
good
because
they confirm
our
prejudices.
Thus, we
may
become
prisoners
of
our
assumptions.
Confirmation bias can also be found
in
anxious
individuals,
who
view
the
world
as
dangerous. For
example, a person with low self-esteem is highly sensitive to being ignored by other people, and they constantly monitor for signs that people might not like them. Thus, if you are worried that someone is annoyed with you, you are biased toward all the negative information about how that
person acts toward you. You interpret neutral behavior
as
indicative
of
something
negative.

Wishful
thinking
is
a
form
of
self-deception,

such
as
false
optimism.

in a way that isn’t determined by feelings or prejudices
such as stating: just this one; it’s not that fattening; I’ll stop smoking tomorrow. Or when someone is “under the
2
influence” he feels confident that he can drive safely even after three or more drinks.
Self-deception can be like
a
drug, numbing you from harsh reality or turning a blind eye to the tough matter of gathering evidence and thinking. As Voltaire
7 commented long ago, “Illusion is the first of all pleasure.” In some cases, self-deception is good for us. For example, when dealing with certain illnesses, positive thinking may actually be beneficial for diseases such as cancer, but not diabetes or ulcers. There is limited evidence that believing that you will recover helps reduce your level of stress hormones, giving the immune system and modern medicine a better chance to do their work.
In
sum,
people
are
prone
to
believe
what
they
want
to
believe.
Seeking
to
confirm
our
beliefs comes
naturally, while
it
feels
strong
and
counterintuitive
8
to
look
for
evidence
that
contradicts our
beliefs.
This
explains
why opinions
survive
and
spread.
Disconfirming
9
instances
are
far
more
powerful
in
establishing
the
truth.
Disconfirmation would require looking for evidence to disprove it.
The take-home lesson here is to set your hypothesis
10 and look for instances to prove that you are wrong. This is perhaps a true definition of self-confidence: the ability to look at the world without the need to look for instances that please your ego.
For group decision-making, it is crucial
11 to obtain information from each member in a way that they are independent. For example, as part of a police procedure to derive the most reliable information from multiple witnesses to a crime, witnesses are not allowed to discuss it prior to giving their testimony. The goal is to prevent unbiased witnesses from influencing each other. It is known that Abraham Lincoln intentionally filled his cabinet with rival politicians who had extremely different ideologies.
12 When making decisions, Lincoln always encouraged vigorous debate and discussion.
