Social skills as a science
@Divia: Do we know how much the show is "rigged"? From what I've read, reality TV producers often try to artificially push or engineer events, eg. get people to fight because that makes ratings go up.
Implicit models can't be shared or standardized, though; you're mostly limited to what you can learn by yourself. Obviously, any kind of lab experiment has to leave stuff out, but the trade-off for doing that is that you can replicate things and accumulate knowledge collectively (http://lesswrong.com/lw/2s/3_levels_of_rationality_verification/). Re training, tennis is also an unusual example, in that it operates almost entirely on very short timescales. I think it's reasonable to say that, eg., the US Navy SEALS are at the peak of human training, and they use a complex combination of things, from realistic simulations to special-purpose exercises to general exercises like push-ups to abstract knowledge of military tactics and stuff.
@Qiaochu: IME, many people won't trust you if you're too transparent, on the reasonable basis that if you share everything freely, you'll also share stuff that they don't want others to know about. This varies a lot based on circumstances, of course :)
