Does wanting to pee make us make good decisions?

Movie or series? Choose Chinese or Japanese food? Burger or pizza? Sometimes making worldly decisions can be very complicated, but according to a 2011 study, when we have to make a decision we endure the desire to pee may we decide to less impulsive way.

Those who are Big Bang Theory fans will surely remember the episode in which Sheldon Cooper couldn't choose between buying an X Box One or a PS4. In that scene, Sheldon cites a study by researcher Mirjam A. Tuk, from a Dutch university, and indeed that study exists. It was published in 2011 by Tuk, Debra Trampe and Luk Warlop in the journal Psychological Science and that same year they won the award Ig Nobel of Medicine, to a curious investigation that "make people laugh but then think".

Tuk and his colleagues conducted several studies to test their hypothesis that inhibitory signals, such as containing urine, they can pass from one field to different ones and increase impulse control.

In two of these studies, half of the participants drank about 700 milliliters of water while the rest drank only 50 milliliters. Then they had to decide between getting a small reward the next day or a bigger reward later. They were raised, for example, to receive $ 16 a day later or $ 30 after 35 days.

Who they drank more water and were in a hurry to go to the bathroom they were more likely to choose the greater reward, even if they had to wait longer to receive it.

These results seem to contradict those of other studies that suggest that self control in one area it hinders the ability to control itself in another. Tuk and his collaborators recognize it but believe that it may be due, among other things, to the fact that less automatic forms of control have been studied than that of containing urine.
