ответ: In my opinion people always want to see the future. Doubts and uncertainty make human to look for the support in subjects. Come to think of it, people try to free themselves of responsibility in unpleasant situations. If you are sure that you'll be unluck because of coming back to home without looking at the mirror – you'll be. It doesn't mean that superstitions are truly. Human's psyche is just structed in this way. When we believe in something – it 'happens'. For someone phrase 'Pregnant mustn't to knit' is just a prohibition, for someone else it means that static load disturbs blood circulation and it's unhealthy for the baby. On the other hand superstitions are the reasons of confidence of many people. A person is able to change the results of work, only relying on his favorite superstition.

The amulets were returned to the first half of the group before the start of the experiment, and the other was told that there was a hitch and the talismans would be returned after work.Those participants to whom their things were returned showed better results, while the second group admitted that they experienced anxiety and uncertainty.
