Chapter 13
Cognitive Biases: Short cuts and Dead ends
Over 180 cognitive biases have been
identified by psychologists and economists. We won’t cover them all here. But many
fall into the following four categories based on human limitations:
We
need to act fast, so…
To stay focused, we favor the
immediate, relatable thing in front of us. [Present bias]
We favor simple-looking options and
complete information over complex, ambiguous options. [Ambiguity bias]
To avoid mistakes, we aim to preserve
autonomy and group status and avoid irreversible decisions. [Status Quo bias]
To get things done, we tend to complete
things we've invested time and energy in. [Sunk Cost fallacy]
To act, we must be confident we can
make an impact and feel what we do is important. [Illusion of control]
We’d rather do the opposite of what
someone is trying to make you do. [Reactance]
There
is not enough meaning in the available information, so…
We fill in characteristics based on stereotypes, generalizations, and prior history. [Group attribution error]
We tend to find stories and patterns
even when looking at sparse data. [Clustering illusion]
We project our current mindset and
assumptions onto the past and future. [Pessimism bias]
We think we know what other people are
thinking. [Illusion of transparency]
We simplify probabilities and numbers
to make them easier to think about. [Murphy's Law]
We imagine things and people we are
familiar with or fond of as better. [In-group bias]
There
is too much Information for our brains to process, so…
We are drawn to details that confirm
our own existing beliefs. [Confirmation bias]
We notice flaws in others more easily
than in ourselves. [Naïve cynicism]
We notice when something has changed. [Anchoring]
Bizarre, funny, visually striking, or
anthropomorphic things stick out more than non-bizarre/unfunny things. [Humor
effect]
We notice things already primed in
memory or repeated often. [Availability heuristic]
We
are unsure of what we should remember, so…
We discard specifics to form
generalities. [Prejudice]
We store memories differently based on
how they were experienced. [Levels of processing effect]
We reduce events and lists to their key
elements. [Recency effect]
We edit and reinforce some memories
after the fact. [False memory]
Let’s use an example of how cognitive biases affect politics and public policy today. Unfortunately, in the year of this writing, the subject of Climate Change has become a political point of contention. Please bear with me if you feel the belief in climate change is an anti-free-capitalism hoax or just normal climate fluctuation or, if true, certainly not caused by humans. There is a chance you are correct. But for the sake of illustration, let’s assume the consensus of scientists from around the world is correct and that their theory that climate change is real, man-made, and a threat to the Earth’s ecosystem is correct. Why would so many people deny its reality? Let’s look at our cognitive biases.
Present
Bias (“Now matters more
than later”): People favor today’s comfort, today’s profit, and today’s
convenience over future consequences. Psychologists call this temporal
discounting.
Normalcy Bias: “If it hasn’t happened yet, it probably
won’t happen.” People assume the future will resemble the past.
Confirmation
Bias: People seek
information that supports their worldview and ignore contradicting evidence.
Status
Quo Bias: It feels easier
and safer to keep doing what we’re already doing.
Optimism
Bias: Optimism becomes a
psychological shield. “Technology will save us.” “Someone else will fix it.”
“We’ve always solved problems before.”
Here
are a few more examples:
Social media companies derive most of
their income from advertising. The more clicks a site gets, the more money it
generates. Consequently, companies program their bots to feed us screens that
confirm our existing interests and biases. They are exploiting our Confirmation
Bias. The danger, of course, is that they cause public opinion to harden at
the extremes without regarding the wishy-washy but more reality-based middle
ground.
Genocide over the ages has been
propagated by negative stereotypes of certain groups. In the 1930s and 1940s, German Nazis portrayed Jews as ugly, greedy, scheming, and dangerous. Such
images fueled the murder of six million Jews during the Holocaust. There were
many reasons European citizens permitted such brutality. But the Prejudice
bias was certainly a major factor. Prejudice toward many ethnic groups
continues to thrive in today’s world.
“In for a penny, in for a pound” is a
saying we can use to justify making poor financial investment decisions. The
related bias is the Sunk Cost fallacy.
As we will see in the chapter on
Memory, every time we remember a long-past but significant event, we tend to introduce errors because we are remembering a memory of a memory of a memory, etc.
This often leads to False Memory, especially when we prefer the more
recent versions.
A thousand more examples could be given
to illustrate our Cognitive Biases. But the important point here is to
acknowledge the value in awareness of our cognitive limitations. We can be
thankful we have heuristics that allow us to make quick decisions when faced
with an avalanche of input. But we can, and should, reserve a degree of
informed humility in our judgments that result in impactful behaviors.
In Chapter 14, we fill in more details
about the human nature element we briefly touched on above – Memory.
