about uniqueness and creativity:

If you model intellectual discovery in the civilization as a search problem, individuals are heuristic agents in a large scale ant colony process. If the agents have highly correlated internal biases, agents that arrive at the same point in the search space are more likely to follow the same paths. All discoveries that can be quickly reached using common biases are learned quickly and they are considered mundane and easy. If everyone in the colony would be exact replica of Carl Friedrich Gauss, the search would advance very fast at first, but eventually it would slow down (to some really high constant level) because CFG colony gets stuck in problems that are difficult to CFG.

In this model creativity is partly explained by having atypical or unique bias. Trait psychoticism might be extreme form of this. When a person has atypical point of view in 2-3 different ways at once, they gain the ability to see new paths forward almost constantly.
