The ultimate test of an explanation is…
The ultimate test of an explanation is weather it would have made the event predictable in advance.
Our comforting conviction that the world makes sense rests on a secure foundation:
our almost unlimited ability to ignore our ignorance.
Pernicious
- Tending to cause death or serious injury; deadly: a pernicious virus.
- Causing great harm; destructive: pernicious rumors.
It helps perpetuate a pernicious illusion.
Premonition
- an intuition of a future, usually unwelcome, occurrence; foreboding
- an early warning of a future event; forewarning
Hindsight Bias
A general limitation of the human mind is its imperfect ability to construct past states of knowledge, or beliefs that have changed.
Actions that seemed prudent in foresight can look irresponsibly negligent in hindsight.
Preposterous
contrary to reason or common sense; utterly absurd or ridiculous.
Considering how little we know, the confidence we have in our beliefs is preposterous.
Infantry
- soldiers or military units that fight on foot.
2. a branch of an army composed
Dispassionate
Not influenced by strong feelings or emotions; objective; impartial: a dispassionate reporter.
Illusion of Skill in the Financial World
Why do investors, both amateur and professional, stubbornly believe that they can do better than the market, contrary to an economic theory that most of them accept, and contrary to what they could learn from a dispassionate evaluation of their personal experience?!
Potent
- possessing great strength; powerful
- (of arguments, etc) persuasive or forceful
- influential or authoritative
- tending to produce violent physical or chemical effects: a potent poison.
- (of a male) capable of having sexual intercourse
The most potent psychological cause of the illusion is…
Pundit
- an expert; A source of opinion; a critic: a political pundit/ financial pundits
- (Education) (formerly) a learned person
- (Hinduism) Also called: pandit a Brahman learned in Sanskrit and, esp in Hindu religion, philosophy or law.
To answer these questions, political pundits must jettison the clichés that have shaped Western views on Central Europe these last few decades.
“The Hedgehog and The Fox”
Hedgehogs have a theory about the world, are confident in their forecasts and especially reluctant to admit error. They are opinionated and clear, which is exactly what TV producers look for: two hedgehogs on different sides of an issue, each attacking the idiotic ideas of the adversary, make for a good show!
Foxes, by contrast, are complex thinkers. They don’t believe that one big thing drives the march of history. Instead the foxes recognize that reality emerges from the interactions of many different agents and forces, including blind luck, often producing large and unpredictable outcomes. They are less likely to be invited to participate in television debates.
Versatile
- capable of or adapted for many different uses, skills, etc
- variable or changeable
(Paul) Meehl Pattern
Statistical predictions (formulas) usually work better than expert opinions.
Several studies have shown that human decision makers are inferior to a prediction formula even when they are given the score suggested by the formula!
The experts who evaluate the quality of immature wine to predict its future price have an extra source of information that makes things worse: they can taste the wine.
But the statistical formula takes into account that the effect of vintage can be only due to variations in weather. It won’t be overconfident in some baseless intuition or personal impression.
Result: The formula predicts the future prices much more accurately than the current prices of young wines do.
Robyn Dawes’s article “The Robust Beauty of Improper Linear Models in Decision Making”
A formula that assigns equal weights to all the (common sense) predictors is likely to be just as accurate in predicting new cases as the multiple-regression formula.
Three basic conditions for acquiring expertise
Probable validity of intuitive expert opinions
An environment that is sufficiently regular to be predictable
An opportunity to learn these regularities through prolonged practice
Availability of rapid and unequivocal feedback about the correctness of thoughts and actions
Intuition cannot be trusted in the absence of stable regularities in the environment!
Planning Fallacy
Plans and forecasts that: Are unrealistically close to best-case scenarios Could be improved by consulting the statistics of similar cases (outside view+reference class forecasting)
Sanguine
- Cheerfully confident; optimistic: sanguine about the prospects for an improved economy.
- Of the color of blood; red.
- Of a healthy reddish color; ruddy: a sanguine complexion.
Having the temperament and ruddy complexion formerly thought to be characteristic of a person dominated by this humor; passionate
