I don't necessarily agree with your point of view, but these two concepts were new and interesting to me. Posting their meanings for others that haven't heard of them either:

> Phrenology

Pseudoscience which involves the measurement of bumps on the skull to predict mental traits.

The study of the conformation of the skull as indicative of mental faculties and traits of character.

> Chesterton's fence

Principle that reforms should not be made until the reasoning behind the existing state of affairs is understood.
