> People who screen resumes tend to assume that you are unemployed because of one or more other undesirable traits you have, like a tendency to be irresponsible or violent and antisocial. This assumption is a mix of broken societal wisdom and an association fallacy. FWIW, there's another fallacy committed when they themselves become unemployed; everyone else unemployed is a antisocial lunatic, but they are a good person who has simply fallen on rough times -- total cognitive dissonance, but they don't notice, even when it is pointed out to them.
For anyone interested, it's called the actor-observer bias: http://en.wikipedia.org/wiki/Actor-observer_bias
