What Drives Blindness from Black Swan Events?
from Dr. Nassim Taleb's book, "Fooled by Randomness"
In his book, Taleb describes a black swan as an event that: Is so rare that even the possibility that it might occur is unknown. Has a catastrophic impact when it does occur. Is explained in hindsight as if it were actually predictableCommon Pitfalls
- Focusing on preselected segments of the seen and generalizing from it to the “unseen” Result is CONFIRMATION BIAS
- Fooling ourselves with stories that cater to human need to discern patterns and simplify with models – NARRATIVE FALLACY
- Behaving as if the Black Swan does not exist – HUMAN NATURE
- Mistaken assumptions about the odds of these events caused by the distortion of SILENT EVIDENCE and LUNIC FALLACY (game theory)
- Focusing on a few well defined sources of uncertainty on too specific a list of BLACK SWANS (at the expense of others that do not easily come to mind).
Notes
We lack imagination and repress it in others (prologue)
Some kinds of definitive Closed Beliefs Need to Be Avoided 55
A series of corroborative events is NOT necessarily
evidence. Once your mind is inhabited with a certain viewpoint, you will tend
to only consider instances proving you to be right. Paradoxically the more
information you have, the more justified you will feel in your views. (demonstrated over and over in studies) 56-59
You know what is wrong with a lot more confidence than you
know what is right 58
Post event we rationalize and reshape memories. 70-74
If your life came under serious threat, having survived it
you retrospectively underestimate how risky the situation actually was. 113-118
SILENT EVIDENCE – Pervades history. Don’t get input from the dead, failures, and
most importantly “real hero’s” who prevent Black Swan’s. We glorify those who left their names in the
history books at the expense of those contributors about whom our books are
silent. It serves to mask the randomness of “Black Swan’s” (for good and bad
BS). Prologue, 101-107
Governments are great at telling you what they did, but not
what they did not do- a form of “phony philanthropy” helping people in a
visible and sensational way without taking into account the unseen cemetery of
invisible consequences (e.g., Katrina disaster help instead of cancer
research). 111
The fact we got here by accident, doesn’t mean we should
continue to take the same risks.
A nerd is simply someone who thinks exceedingly inside the
box 125
LUNIC FALLACY – Assuming that statistics (game theory)
applies to random events that can go out of control (e.g., stock market, earthquakes,
flight testing). In real life you do NOT know the odds, you need to discover
them. 127
We tend to underestimate the role of luck in life in
general and overestimate it in games of chance 129
We are demonstratingly arrogant about what we think we know. Reference the 98% certainty studies. That
demonstrate the difference between what people actually know and how much they
think they know 138-140
One main effect of information: impediment to knowledge (pg
144)
Humans are victims of an asymmetry in the perception of
random events. We attribute our successes to our skills, and our failures to
external events outside our control, namely to randomness. Pg 152
