Mood maintenance hypothesis
People in a good mood avoid risks and effort that might spoil it.
What it means
The mood maintenance hypothesis holds that happy people are motivated to preserve their pleasant state and therefore behave conservatively, avoiding gambles, bad news, and effortful tasks that could undermine the mood. Because a good mood is itself a valued asset, the potential loss of feeling good is weighed alongside the objective stakes of a decision, making positive affect a sometimes paradoxical source of caution. Sad people, by contrast, have little positive mood to protect and may take risks in hopes of mood repair. The account complicates any simple claim that good moods make people reckless, showing instead that the direction depends on what the mood has to lose. It connects affect regulation directly to risk taking and information seeking.
Examples
A person enjoying a great evening declines a tempting but uncertain bet, unwilling to risk the sour feeling a loss would bring.
Riding high after a promotion, you leave the letter with your test results unopened on the hall table until Monday. The week feels too good to risk spoiling.
A team fresh from winning a big account quietly picks the safe repeat project over the ambitious pitch, unwilling to trade a glow for the chance of a public flop.
First described in Isen and colleagues (1980s).
