Pragma Synesi - interesting bits

What should you really fear?

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.

How Anecdotal Evidence Can Undermine Scientific Results

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…”
Something to watch for - both in self and in others.

Sleep loss produces false memories

It seems false memories are formed at the time of recall, which has interesting potential consequences for using sleep deprivation as an interrogation technique.

And chalk one up for coffee for the sleep deprived.
