We're showing for the first time that incidental emotions from one situation can exert a causal effect on economic behavior in other, ostensibly unrelated situations.

Anger triggers a sense of certainty as well as a sense of control.

Analyses of facial expressions revealed that the more fear individuals displayed in response to the stressors, the higher their biological responses to stress. By contrast, the more anger and disgust (indignation) individuals displayed in response to the same stressors, the lower their responses.

We didn't focus on how they felt after they bought things. Instead we focused on what led up to the buying decision.

These are the most exciting data I've ever collected.

Anger can sometimes be adaptive. We're showing for the first time that when you are in a situation that is maddening and in which anger or indignation are justifiable responses, anger is not bad for you.

When you get really mad, you also have really large cardiovascular responses.

Having that sense of anger leads people to actually feel some power in what otherwise is a maddening situation.
