How hereditary can intelligence be?

Researchers have in recent years scaled back their estimates of the influence genetics plays in intelligence differences. The previous figure of 80 percent is outdated. Nisbett says that if you take social differences into account, you would find "50 percent to be the maximum contribution of genetics."

Multitaskers:

  • Did a significantly worse job filtering out the irrelevant information.
  • Took longer than non-multitaskers to switch among tasks.
  • Less efficient at juggling problems.
  • Tended to search for new information rather than accept a reward for putting older, more valuable information to work.
  • Process visual and auditory input less efficiently.
  • Become reliant on more a more simplistic, and often inferior, thought process, and can thus fall prey to perceptual decoys.

Maybe multitasking gives the illusion of productivity without achieving higher volume...
