Emotional Arousal

When emotionally aroused (angry, frightened, excited, sexually aroused), decision-making quality degrades dramatically. Dan Ariely's research shows that in 'hot states,' people make predictions and commitments they would never make in 'cold states'—and they systematically fail to predict this shift. Emotional arousal narrows attention, increases risk-taking, reduces empathy, and impairs long-term thinking.

When to use it

When you notice strong emotions while facing a decision. When designing decision processes (build in cooling-off periods). When evaluating commitments made under emotional pressure.

How it can help

Explains why decisions made in anger, fear, or excitement are so often regretted. Provides the foundation for cooling-off periods, HALT checks, and the general principle of never making important decisions in heightened emotional states.
