WEIRD people have a bad habit of universalizing from their own particularities. They think everyone thinks the way they do, and some of them (not all, of course) reinforce that assumption by studying themselves. In the run-up to writing the book, Henrich and two colleagues did a literature review of experimental psychology and found that 96 percent of subjects enlisted in the research came from northern Europe, North America, or Australia. About 70 percent of those were American undergraduates. Blinded by this kind of myopia, many Westerners assume that what’s good or bad for them is good or bad for everyone else.
This is a painful reality. It's also even more specific to the current Republican party. Do as we say, not as we do.
This is the sort of example that David Dylan Thomas will appreciate.
