I don't know if I should take that to mean that my writing is praiseworthy for its clarity, or that I've become repetitive. In any case, that's an excellent question!

An immediately obvious example would be analogous advice for women. From what I know about the relevant matters, my impression is that if accurately formulated, it would in fact end up sounding even worse for mainstream sensibilities than the PUA stuff. Similarly for further advice (for both sexes) that builds on the PUA insights for successful long-term relationships and marriages.

Another topic that comes to mind is parenting. I'm not familiar with the self-help literature in this area, but there are some quite ugly truths which I'd bet these books don't say, for example how depressingly little you can do beyond the limits imposed by heredity. Moreover, fully accurate no-nonsense advice about what you can do to maximize your kids' expected success in life and happiness would require a cynical analysis of many respectable social institutions, customs, and beliefs, to the point where it would probably be too offensive for mainstream sensibilities.

Some other examples I can think of are too sensitive and potentially offensive to describe with a few casual words, so I'll stop at this for now.
