Social psychology and cognitive biases.
Strategy and Decision-Making Biases
Affective Errors
Tendency to make decisions based on what we wish is true.
Applies to folks we like, which can affect the quality of our judgement. Brooke Harrington's research on investment clubs showed clubs formed primarily through professional bonds — as opposed to social ones — earned higher returns. “One of the things that can torpedo group performance is when people are too socially enmeshed with one another. They can become reluctant to really be direct and honest with one another.”
Attribution Bias
When trying to make sense of the world, we are prone to overemphasizing certain things at the expense of others. For example, we are more likely to attribute behavior to disposition ("This is who they are") than to situation ("This is what was going on"). This is known as Fundamental Attribution Error.
Another example is false consensus effect, where we overestimate how widely our views are shared with others. This is a form of representativeness bias (the presumption that people or events share the features of other members in that category). Said another way, it's The Majority Illusion. Another example is the Abilene Paradox.
You can leverage this effect to get people's true opinions. If you ask someone what they think about something, they have an incentive to say what they think you want to hear. If, however, you ask them, "What do you think others think?", it's likely that you'll get a good picture of what they think, thanks to these attribution biases.
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).

Survivorship Bias
Focusing on things that succeeded, while ignoring things that failed. Another corollary to "correlation ≠ causation."
Said another way:
Be wary of extrapolating from positive deviance!
