According to the study, angry consumers were 37% more likely to choose a default option than sad individuals. In contrast, sad individuals were not different from neutral mood individuals when it came to consumer decision making.
This study shows that all negative emotions are not the same. For instance, if you are choosing different retirement options, you are more likely to stick with the default retirement option (often company stock) if you are angry compared to sad. Sad people tend to examine all the options more carefully and choose the best available option. The moral: Don't make important decisions when you are angry.
