* humans are causal thinkers
  - they are better of thinking from cause to effect
  - they may fink from effect to cause too 

* humans are worse at other kinds of thinking
  - statistical
  - abstract
  - arithmeticz

* causal thinking requires modeling the world, introducing action and predicting
  reaction

* pavlov's conditional reflexes do not always work. Humans/animals are
  a lot better at associating _causal_ events than random events. For example
  taste with getting sick (rats)

* knowledge is distributed, individual humans know a lot less than they 
  think they do.

* humans rely on environment to provide information about itself (where the books are)
  so no independent "detailed" concept of the world outside is formed in one's head

* more so when they rely on other humans and the cooperation with them

* evolutionary theory of brain development: needed to exist in large social groups
  and hunt big game

* if discussion switches from moral values to causal: how to solve the problem,
  it becomes more constructive

* individual IQ is less important if people work in groups
  more useful is a C - a factor as to how much each individual
  contributes to the group
  -- can be measured across goups

  what is intelligence: ability to solve cognitive problems, humans
  distribute knowledge and work in groups, hence group intelligence

* illusion of cognitive depth

* knowledge fiends and foes
  - people tend to ignore extra data (even relevant data) in making
    a decision; this hurts if the decision is not intuitive
  - people tend to make decisions on basis of identification with 
    agroup - group thinkers. Marketing exploits that
