YOU HAVE A big decision to make. Whether to put in an offer on a house, say, or change jobs. Which of the following will help you make the right choice: being in a state of sexual excitement or having a full bladder? Most likely, it is not something you have pondered. Psychologists, however, have long studied the ways that external factors such as these influence our decision-making.
A full bladder, apparently, helps us take more rational, long-term decisions. At least that was the finding of a study carried out by Mirjam Tuk, a professor at the University of Twente in the Netherlands. In an experiment, Tuk tested two sets of participants. The first was told to drink five cups of water; the second to take just five sips. After 40 minutes, they were tested on their decision-making abilities. Tuk says that the group who were, by now, crossing their legs, were better able to exercise self-control and hold out for larger rewards.
