One informal research method that you won’t find written up in any manual is called the Meanest Motherfucker – seek out the meanest, most unlikely candidate for an interview (whether or not they have an oedipus complex) and open them up to a meaningful conversation. Child’s play, if only because mean is subjective, and bound by the limits of our experience of the human condition.
