Availability Heuristic

If you can recall it, it must be important.

Bias towards information or actions you can more easily recall (such as recent news or things with major consequences).

Representativeness Heuristic

Presumption that people or events share the features of other members in that category.

Ed Batista's "Seeing what's not there (The importance of missing data)."

Affective Errors

Tendency to make decisions based on what we wish is true.
