Cognitive Biases - How Your Mind Distorts Reality

I just found this great slideshow through It gives a nice visual summary of the main "psychological tendencies that cause the brain to draw incorrect conclusions", split up into...

  • the 19 social biases.
  • the 8 memory biases.
  • the 42 decision-making biases.
  • the 36 probability / belief biases.

I especially like the memory bias Cryptomnesia, "a form of misattribution where a memory is mistaken for imagination, or the confusion of true memories with false memories". Scary stuff.

Want to get meta? Consider the Bias Blind Spot, or "the tendency not to compensate for one's own cognitive biases"

So do you really make your own decisions? Really?
