The Tragedy of the Commons

Summary: The Tragedy of the Commons is an economic theory that describes how people often use natural resources to their advantage without considering the good of a group or society as a whole. When a number of individuals consider only their own welfare in this manner, it leads to negative outcomes for everybody, as the natural resource becomes depleted.

Confirmation Bias (Wason)

Summary: Confirmation bias is a cognitive error that people make when they are only willing to accept new information when it confirms what they already believe. People who fall into the trap of confirmation bias tend to purposefully seek out evidence that supports already solidified beliefs and purposefully reject any evidence that goes against those beliefs.
