You beat me to it.. the problem is not math (maths is generally correct if it is done by someon who knows).

To make a synthesis of both perception...Culture is a sum of attitudes which give you a plying field, so to speak. It is a playing field of common symbolic objects with a  set of particular players which give new meaning and redifine the playing field.

Exploring the playing field is tough... doinbg it with a survey... probably impossible...

I repeat again Man point...indudually you can not get the playing field of symbolic options...

It is like trying to understand soccer by just looking only at how the legs of a player move... tough...

You at least need to check how the players move so as to know what are the rules of the game.

Most anthropologists prefer the option of "playing the game".. this is.. trying to live among the group of people you are interested in and record them at the same time.

Anf I finish my metaphors here....:)

I therefore claim to show, not how men think in myths, but how myths operate in men's minds without their being aware of the fact. Levi-Strauss, Claude
