Spoiler alert: this is an academic book, social psychology, with lots of carefully constructed experiments involving mostly white college undergraduates. Hmm....
I reconnected with this book because its title had always annoyed me. I don't know many people who believe in a just world. Most people I know will admit that their lot in life has a lot to do with luck. The luck to be born white or not, in the USA or not, during a particular up or down phase of an economic cycle, in a particular cohort -- GenX, Baby Boomer, etc -- has a lot of determinative force.
This book claims that people like winners and recoil from losers. The explanation is that people want to believe they are playing a more or less fair game in life. They make up stories about these winners and losers. They could say of losers "there but for fortune go I" but often they say "wow that person screwed up his chances, and look where he's ended up".
The second, unsympathetic answer was common among test subjects. If these studies were conducted, like many social psych experiments on a particular group, ie, privileged white youth who naively believe in their world because it mostly works for them, does it follow that most people really believe in a just world? Is life really like a football game, with a level playing field and referees who enforce known rules?
The first, sympathetic answer, "there but for fortune go I" is where I stand. I have worked hard and been lucky, others have worked just as hard and failed. So my feeling is to be humble towards the less fortunate especially if I don't know their particular story, and a little more skeptical of the self made success stories that get touted around as morality tales. A lot of where you end up depends on where you started.
Perhaps the message is that you need to look at context, choices, and luck in any one person's life, to discern the real story, and keep yourself from being overly judgmental or overly adoring.
