The Hidden Brain by Shankar Vedantam

The Spotlight Effect -- An honor coffee pot in an office collected three times as much in weeks 1, 3, 5, and 7 of a study than in weeks 2, 4, 6, and 8. The odd numbered weeks features a picture of watching eyes while the even-numbered pictures were of flowers. Workers did not notice the photos.
When a waitress mimicked the customers ordered verbatim after a short delay, tips were 140% larger. Changing the words did not get the increase.
Couples can work together if they achieve in different areas but not if they compete.
Kids learn faces very early. Seventy percent of children studied assigned positive adjectives to white faces and negative to black. Bias weren't coming from parents or teachers. Kids pick it up from what they see.
Our hidden brain is quick to draw conclusions. At middle school age when kids are able to correct these early impressions they start to drop their friends of other races. This is the stage of defining ones group.
When workers change gender to male they are treated better, and when they change to female they are treated worse.
