Fear of the Unknown

A major cause of anxiety in our lives is the uncertainty we all face in the future.

There are certain possibilities that we can predict and prepare for. Known risks, so to say.

However, fear of uncertainty is most severe where the possible distribution of outcomes is unknown or hidden (HT: Barry Ritholtz, Michael Mauboussin). Unknown unknowns, so to say.

Why does the latter produce so much anxiety in some people?

First, imperfect information makes prediction hard. Second, left to their own devices, systems become more random with time (related to the concept of entropy). We seek to impose order onto a world prone to disorder. Finally, many systems are metastable. That is, they should not be stable under given conditions, but somehow manage to stay unchanged. Think a precariously made house of cards. Smallest changes in the environment can bring down metastable systems. The weakness of these constructs may not be evident to people that depend on it. Perhaps the financial crisis of 2008–2009 is a great example of such systems.

Quotes from "The Social Leap"

These are the lines from William von Hippel in his book “The Social Leap” that I found to be incisive and insightful. “The ability to kill at a distance is the single most important invention in the history of warfare, because weaker individuals can attack stronger individuals from a position of superior numbers and relative safety.” “As if division of labor were not enough, Homo erectus then sealed the deal with the single most important innovation in human history: the control of fire.” “Long before the invention of writing (which is only about five thousand years old), human culture had become cumulative by virtue of our oral storytelling traditions .” “When we weigh up the costs and benefits, we see that farming afforded our ancestors some assurances against starvation, but at the cost of various new illnesses, reduced stature and longevity, excruciating halitosis, and often a far longer working day. The end result was that early farmers worked harder to achieve a worse life than ...

The Upside of Disaster

In the previous post , I talked about the tactics rational optimists use to deal with uncertainty: explore and exploit. There are situations where an utter disaster and the resulting uncertainty can change the history for the better. An amazing example is the story of human evolution from chimp-like apes. Here's a brief review of the story told by William von Hippel in “ The Social Leap .” These apes lived in the rainforests of eastern Africa, around 6 million years ago. They ruled the canopy. But then disaster struck. Eastern Africa was tearing away from the rest of the continent, due to plate tectonics. The climate changed. The rainforests disappeared. These apes had to adjust to living in the savannah, at the mercy of great predators. Humans reacted to this disaster by innovating and inventing. Human distinctions — from bipedalism, persistence hunting, to the use of language and tools and our social structure — ultimately are the results of that disaster. They learned to be grea...

Pessimists and Optimists

I discussed before a role of dopamine for motivation and reward-seeking. I want to highlight a paper by  Colin G. DeYoung that tries to establish "a  unifying theory of the role of dopamine in personality."  One of the interesting point that Dr. DeYoung highlights is that " what is uncertain or unpredicted is unique as a class of stimuli in being simultaneously threatening and promising ." The promising nature of uncertainty explains why people like gambling so much. So what do people do when faced with uncertainty, what do people do? They do what every organism is hardwired to do: “… the organism should have two competing innate responses to an unpredicted event— caution and exploration …” I think this is where pessimists (caution) distinguish themselves from optimists (exploration). Pessimists routinely lack the skill to be lucky . Here's DeYoung's overarching theory: “the general function of dopamine is to promote exploration , by facilitating engage...
