Our “anecdotal” brain sucks up all the sensational news a media (vying for higher ad revenues) can muster. This results in some skewed gut feelings of what we should be afraid of.

For me, this is the key quote from the article below:
“…we have evolved brains that pay attention to anecdotes because false positives (believing there is a connection between A and B when there is not) are usually harmless, whereas false negatives (believing there is no connection between A and B when there is) may take you out of the gene pool…”

And chalk one up for coffee for the sleep deprived.
But caffeine helps to boost accurate recall

From this article I have concluded that if you’re on a diet, you shouldn’t be looking through Sports Illustrated swimsuit edition before dinner. But if you run a restaurant, that’s a good magazine to leave in the waiting area.
