8. We'd rather know something bad is coming than not know what to expect.

Researchers who published their work in the journal Nature have found that it's less stressful to know something negative is about to happen (e.g., there's no chance we'll get to a meeting on time) than when we don't know how things will work out (e.g., we might be on time after all). That's because the part of our brain that predicts consequences—whether good or bad—is most active when it doesn't know what to expect. If stepping on the gas will help us beat traffic, we'll go through that stress instead of just accepting that we'll have to come up with a decent excuse when (not if) we're late.
