. Anyway, the most often given example is that of the Hopi tribe and their ritual dance: they dance to bring forth rain - the idea that together they can make it rain is the intended, manifest function of their ritual, but what's in fact far more important (though they didn't presumably fully realize it) is the that the common goal and the enjoyment bring the tribe together and strengthen bonds between its members - the unintended latent function.

(Emphasis mine). I'm going to nitpick a side issue here, but that's a classic example of Western privilege and myopia: assuming that "primitive" people don't know perfectly well that what they are doing has an important social function.
