Satoshi Kanazawa quotes:

Proofs exist only in mathematics and logic, not in science.

If any value is deeply evolutionarily familiar, it is reproductive success. If any value is truly unnatural, if there is one thing that humans (and all other species in nature) are decisively not designed for, it is voluntary childlessness. All living organisms in nature, including humans, are evolutionarily designed to reproduce. Reproductive success is the ultimate end of all biological existence.

A 'multicultural society' is a logical and physical impossibility.

Humans are evolutionarily designed to be paranoid, and they believe in God because they are paranoid,

A theory's assumptions always are and ought to be unrealistic. Further, we should attempt to make them more unrealistic in order to increase a theory's fruitfulness.

There are certain questions that scientists may not ask, or, more accurately, for some questions, there are certain answers that scientists must a priori preclude from consideration.
