The key to good decision making is not knowledge. It is understanding. - Malcolm Gladwell

Our first impressions are generated by our experiences and our environment, which means that we can change our first impressions . . . by changing the experiences that comprise those impressions.

The middle-class parents talked things through with their children, reasoning with them. They didn’t just issue commands. They expected their children to talk back to them, to negotiate, to question adults in positions of authority. If their children were doing poorly at school, the wealthier parents challenged their teachers. They intervened on behalf of their kids. One child Lareau follows just misses qualifying for a gifted program. Her mother arranges for her to be retested privately, petitions the school, and gets her daughter admitted. The poor parents, by contrast, are intimidated by authority. They react passively and stay in the background.

our unconscious reactions come out of a locked room, and we can't look inside that room. but with experience we become expert at using our behavior and our training to interpret - and decode - what lies behind our snap judgment and first impressions.
