One book, I currently see from time to time, is entitled Blink.  Blink examines the value of a quick decision.   One of the studies Blink discusses involves showing a group of people short clips of teachers giving a lecture (with no audio).  Another group is shown still photos of the same teachers from the clips.  Both groups are asked to rank the teaching ability of the teachers based on either the photo or the silent 30 second clip.

The results showed the ratings each teacher received based on photos and clips were remarkably similar to the ratings the same professors received from their full time students after a semester of teaching.   From what I have read so far, Blink supports the notion that a quick decision is often an educated decision.  Although I feel this study simply illustrates our species loyalty to superficial conclusions.

Some people have a natural fear of snakes and others have a natural fear of spiders.  These fears make sense considering the problems our
species has experienced over the centuries do to both species.  Perhaps these fears are based on the same instinctual knowledge that
allows us to make smart quick decisions.

The human brain is the product of years of learning things the only way us humans truly learn anything…the hard way.

I discovered my fear of electricity by touching an electric fence.  Twenty minutes later I discovered that it is impossible to touch a electric fence
twice.  My curiosity made me want to “make sure it was an electric fence” but my brain would not allow my hand to make contact.

Just as I learned not to touch the fence again perhaps the human race has learned from collective experience and perhaps there is something to that gut feeling that helps us make life’s quick decisions.  Although I have only read the fist 50 pages of Blink, I feel I am able to review the book with confidence using the “blink of an eye” decision making the book examines.
