This is an article on human reasoning fallibility as it pertains to trading/investing that is well worth a read.

I found it earlier and though I'd share it:

  • sharks actually save the lives of swimmers
  • On average, each swimmer killed by a shark saves the lives of ten others by keeping people out of the water: "Every time a swimmer is killed, the number of deaths by drowning goes down for a few years and then returns to the normal level. The effect occurs because reports of death by shark attack are remembered more vividly than reports of drownings."

Stick your examples of how this works in markets in the comments if you like.
