Thinking, Fast and Slow

This book is interesting, but  I suggest reading or listening to a summary (I like Blinkist) rather than taking the time to read the entire book.  It’s too long winded and scientific, and academic for me.

SUMMARY:

Human minds have 2 systems:

System 1- Impulsive, instinctive automatic,  intuitive. This system is legacy of evolutionary past. Making rapid actions and judgments can be a survival advantage, but not understanding that our minds are still working even without our conscious effort, can be a disadvantage in life.

System 2- Calculating, thoughtful, deliberate. It’s about maintained focus, higher intelligence, forming beliefs, etc.

Being lazy and using System 1 when we should utilize System 2, can cause us to make mistakes.

Priming- exposure to something causes us to summon thoughts about something else. It effects the way think,  but also the way we act.

Heuristic- How the mind use shortcuts to make quick decisions.

  • The mind can overuse these
  • Substitution heuristic- Answering an easier question than what was actually asked.
    • Instead of doing research, we just take the easy route.
  • Availability heuristic- Overestimate something you hear about more. The media putting something in our minds that helps rating is a perfect example.

Experiencing vs. Remembering self- WE HAVE FAULTY MEMORIES

  • Experiencing is more accurate-feelings during an event occurring
  • Remembering- Less accurate b/c it registers memories AFTER the event, but it dominates the memory. Reasons why it dominates the memory:
    • Duration neglect- Ignoring the duration in favor of a particular memory from it
    • Peek end rule- overemphasizing what happens at the end

Cognitive ease vs. Cognitive strain

  • Ease-When something is simple, and system 1 can handle it automatically.
  • Strain-System 2 double checks us, but we’re less creative and able to influence.
    • Practicing a speech 100 times so it becomes in a state of cognitive ease makes you sound much more influential.
