According to a new study people in a bad mood are better at doing tasks that require attention to detail.
Basically, since you’re grumpy you are more likely to analyze and scrutinize any task in front of you. Which can make you perform in a more efficient manner.
And it’s not just angry moods that help, any negative mood like sadness can boost this analytical behavior as well.
Also in this study they found that women are more likely to re-analyze a situation when in a bad mood.
