Unlike those who are happy, the grumpy seems to make better decisions and are less gullible , as shown by the experiments.
Although the mood encourages creativity, fosters misery prudence and careful thought , according to Professor Joe Forgas. http://howtobet.net/forum/viewtopic.php?f=4&t=130528

The Forgas asked volunteers to watch different films and focus on the positive and negative events in their lives, either to feel grumpy or cheery.
Then asked the volunteers to participate in a series of tasks, such as to judge the truth of urban myths and submit their experiences of events and situations that were themselves eyewitnesses. http://forums.glahost.com/showthread.php?tid=61040
The performance of those who were in a bad mood was much better than those who felt cheery-made fewer mistakes and were better communication.
As stated by Professor Forgas: « Although the positive mood seems to promote creativity, flexibility, cooperation and trust, negative mood encourages a more careful and attentive thinking, and greater attention to the external world.

The study also found that sad people could exhibit better their situation through written arguments, which according to Forgas showed that " a slightly negative mood encourages a more specific, adapted and ultimately more successful way of communicating. "
Previous study that had shown that the weather has similar effects in humans - rainy and cloudy days sharpen memory, while sunny days make people forget more.
