Decisions, decisions! Our lives are full of them, from the small ones to the life-changing. The right to choose is central to everyone. Yet sometimes we make bad decisions that leave us unhappy or full of regret. Can science help?

Most of us know little about the mental processes that lie behind our decisions. Luckily, what psychologists(心理学家)are finding may help us all make better choices. Here are some of their amazing discoveries to help you make up your mind.

Consider your emotions. You might think that emotions are the enemy of decision making, but in fact they are a part of it. Whenever you make up your mind, your brain’s emotional centre is active. University of Southern California scientist, Antonio Damasio, has studied people with damage to only the emotional parts of their brains , and found that they were unable to make basic choices about what to wear or eat. Damasia thinks this may be because our brains store emotional memories of past choice, which we use to help the present decision-making.

However, making choices under the influence of an emotion can greatly affect the result. Take anger, for example. A study by Nitika Garg of the University of Mississippi and other scientists found the angry shoppers were more likely to choose the first thing they were offered rather than considering other choices. It seems that anger can lead us to make quick decisions without much thinking.

All emotions affect our thinking and motivation（动机），so it may be best to avoid making important decisions under their influence. Yet strangely there is one emotion that seems to help us make good choices. The American researchers found that sad people took time to consider the various choices on offer, and ended up making the best choices. In fact many studies show that people who feel unhappy have the most reasonable view of the world.
