The brilliant chapter on David Rosenhan's experiment, in which volunteers presented vague symptoms at psychiatric facilities and were immediately admitted, proving that the diagnosis of "mental illness" is a largely contextual affair, is the most flamboyant and revealing example of Slater's method.
Another chapter looks at Leon Festinger's experiment with infiltrating a doom's day cult and seeing what happens when doom does not arrive at the appointed hour. What happens is "cognitive dissonance"--which I would call "elaborate rationalization.
Still another chapter is devoted to the famous "Lost in the Mall" repressed memory experiment by Elizabeth Loftus, who showed how a false memory of being lost in the mall as child could be suggested to people and how they would not only come to believe it, but would confabulate all sorts of "remembered" detail around an event that never happened (laurenslater.com, amazon.de)
