I think cultural and educational background is a factor, but not in the fashion of "persons who had an education of X type in culture Y have superior prescience", but rather "persons who had education experiences of X, Y, Z, and developed in cultures A, B, C, D, Q, R have superior prescience", as having a broader gamut of experiences to draw from allows you to eliminate many biases from which you'd otherwise suffer.
