Model thinking (https://www.coursera.org/learn/model-thinking)

Taught by Prof. Scott E. Page, teaches about models in several fields and how they're used to aid thinking about complex issues by careful design and usage.

A couple of insights: all models are wrong but some are useful. Having many models about a situation to help your thinking is better than having only one, and much better than none. Complex models are not necessarily better than simple ones.
