I was interested to hear on NPR other day that 2 cognitive psychologists were able to pinpoint the location of a sunken Australian ship from WWII.
They used the techniques of the discipline to examine the stories — previously discounted — of the eye witness accounts of nearly 300 Germans who were rescued from a German ship involved in the same skirmish. The stories that were told by the eyewitnesses were even more fuzzy than most eye witness accounts.
The psychologists were able to pin point the spot that had the most in common with all the different versions, and came within less than 3 miles of where the ship Sydney actually was found.
While this may not be all that helpful in finding other ships (unless there were lots of eye witnesses), it might be useful in figuring out where our politicians really stand. We could map out all of Rick Perry’s or Barak Obama’s comments about social security and see where the truth is buried!
I am not meaning to imply these guys have different positions just because of faulty memories, but the distortions of memories that we all have may provide the statistical noise that allows us to find what was the essence of what they were saying.
