Kahneman's Mind-Clarifying System(s)

Feeling IS fast thinking. And emotions aren't always guilty of being irrational. Whenever pondering minds, always bear in mind Daniel Kahneman’s teachings on the brain.

1. Feeling is a form of thinking. Both are ways we process information, but feeling is faster. That’s the crux of Daniel Kahneman’s mind-clarifying work.

2. In Thinking, Fast and Slow, Kahneman says social scientists until recently broadly believed that “people are generally rational…[and that] emotions…explain most [departures] from rationality.”

3. But research shows it’s unsafe to presume that emotions are guilty—”cognitive bias” studies trace systematic “errors to the… machinery of cognition…rather than corruption…by emotion.”

4. Kahneman using the brilliantly bland terms “System 1” and “System 2”—unburdened by the baggage of old associations—sidesteps centuries of confusion (and Freudian fictions).

5. System 1 “is the brain’s fast, automatic, intuitive approach,” System 2 “the mind’s slower, analytical mode, where reason” operates.  But “System 1 is...more influential… steering System 2 to a very large extent” (—>Hume’s “Reason Is and Ought Only to Be the Slave of the Passions,” 1738).

6. The measurable features of System 1 and System 2 cut across prior categories. System 1’s intuitive/emotional/fast information-processing is often logical and useful (e.g. intuition = System 1 pattern “recognition”). Conversely, System 2 thinking, despite being conscious and deliberate, can work badly, even irrationally (e.g. here, here, here).

7. Kahneman, astonished that economists were modelling people as “rational, and selfish” with stable tastes, whereas to psychologists it’s “self-evident that people are neither fully rational nor completely selfish” and have “anything but stable” tastes, launched behavioral economics.

8. Kahneman’s framework has limitations, e.g. cognitive biases can have two sources of error, the seemingly suboptimal behavior and the norms economists (mis)label “rational.”

10. Kahneman’s focus on explicit numerical decisions discounts that we didn't evolve to think numerically. Conscious math is a second nature skill, needing System 2 training (—>Hobbes “Reason is not...born with us… but attained by industry/training,” 1651).

11. Kahneman says we’re bad “intuitive” statisticians, but babies do astonishing System 1 statistical reasoning. And human speech requires strong intuitive stats (still beyond our best technology).

12. And cognitive biases might be (automatically triggered) bad System 1 habits rather than built-in brain bugs.

13. Limitations aside, whenever pondering cognition, bear in mind the distinct traits of System 1 and System 2. Mapping mental skills onto those labels can clarify your thinking about thinking.

  • Our theories about the world, even about history or the geopolitics of the present, tend to be shaped by Anglo perspectives of the Western industrial democracies, particularly those in the United States and the United Kingdom.
  • The West, however, is not united. Canada, for instance, acts in many ways that are not in line with American or British policies, especially in regard to populism. Even if it were united, though, it would not represent most of the world's population.
  • European ideas, such as parliamentary democracy and civil service, spread across the world in the 19th century. In the 20th century, American values such as entrepreneurialism went global. In the 21st century, what we're seeing is an Asianization — an Asian confidence that they can determine their own political systems, their own models, and adapt to their own circumstances.

Vikings unwittingly made their swords stronger by trying to imbue them with spirits

They didn't know it, but the rituals of Iron Age Scandinavians turned their iron into steel.

Culture & Religion
  • Iron Age Scandinavians only had access to poor quality iron, which put them at a tactical disadvantage against their neighbors.
  • To strengthen their swords, smiths used the bones of their dead ancestors and animals, hoping to transfer the spirit into their blades.
  • They couldn't have known that in so doing, they actually were forging a rudimentary form of steel.

Why the ocean you know and love won’t exist in 50 years

Can sensitive coral reefs survive another human generation?

  • Coral reefs may not be able to survive another human decade because of the environmental stress we have placed on them, says author David Wallace-Wells. He posits that without meaningful changes to policies, the trend of them dying out, even in light of recent advances, will continue.
  • The World Wildlife Fund says that 60 percent of all vertebrate mammals have died since just 1970. On top of this, recent studies suggest that insect populations may have fallen by as much as 75 percent over the last few decades.
  • If it were not for our oceans, the planet would probably be already several degrees warmer than it is today due to the emissions we've expelled into the atmosphere.
