This book was reasonably interesting, but not all I had hoped it would be. It does provide a wide catalogue of asshole types and tests to determine whether someone else (or you) is the asshole, but its coping strategies are mostly obvious and more folk psychology peppered with the occasional study than novel strategies. Perhaps I've read too much social psychology from the original sources already (the author constantly cites Kahneman, Dunning-Kruger effect, and other well-known themes in modern behavioral psych), or perhaps the book is just aimed at an audience with less familiarity with such topics. The author goes through strategies such as reframing (this is the other person's problem, not mine), minimizing (other situations have been much worse), "love bombing" (killing them with kindness), empathizing (thinking of them as "porcupines with a heart of gold"), avoidance (staying out of their way), non-reactivity (don't let them get to you, e.g., "that's an interesting point, I'll take that into consideration"), etc. Reasonable strategies, certainly, but nothing too surprising. Perhaps the most interesting part of the book for me was about the psychology of revenge (here he cites Eric Jaffe's well-known article), concerning how revenge could be "sweet" but would actually result in maintaining the hurt in one's mind for longer, and even when executed would rarely provide relief. The studies showing the contagiousness of assholery were also interesting. The closing words of the book were also a bit disappointing, even victim-blaming - "it's on you, but you're not alone." I suppose it's on you to make the best of your situation, but that seems to be a weak way to close. I preferred his earlier mantras, such as "be slow to judge others as assholes, and quick to judge yourself," and the "Da Vinci" rule, that it's easier to resist at the beginning than at the end (i.e., get out of bad situations quickly). All in all, it was interesting, and a worthwhile read, but a mixed bag in terms of real tools to deal with the assholes in one's life.
