PanActon InstituteThe Spirit Level relied on a succession of dubious scatterplots for evidence. The Inner Level has no shortage of similar graphs, but is more focused on explaining how inequality is supposed to cause so many problems ... if you have your doubts about whether \'shyness\' and \'party anxiety\' are bona fide mental disorders, you will want some evidence. Or, at least, a coherent argument. The problem is that Wilkinson and Pickett are not very good at laying one out. Unable to see a tangent without going off on it, they fill the book with mini-essays about everything ... Through a one-sided interpretation of cherry-picked evidence, they paint an unremittingly gloomy picture of life in \'less equal\' nations.
