normalized, not normal. (https://en.wikipedia.org/wiki/Unit_vector)

theoretically if you add the value-vector of all people together you end up with a long vector that represents the direction of society (even the opposing ones), and you can then normalize this to have the unit vector of society. i.e. what is the "direction of society".

Your skew wr.t. this one (inner product with, or projection on to this) will be some number between -1 and 1 (if we account for opposition I guess)

Basically if both vectors are of unit length, you get the cos(angle between). Completely off kilter would be a score of 0. While "opposed" would be -1
