I found a document on Scribe where Eric Fernandez breaks down cognitive biases into four main categories and gives visual logos for each. I've attached his example of the Social Biases. But there are also: memory, decision-making, and probiblity/belief baises.
I thought this was interesting because of its connection to human behavior and motivation.
