Why do people belive in superstitions?

I think that it's just a feeling that we get when we are presented with one of them. For example we get a feeling like "what if it really turns out true?". In my opinion the'll disappear soon enough. There really isn't much behind them. In some cases people get really desperate, for example many family members of missing individuals turn to psychics to get a little more hope when things are turning out grim. Another good exaple are people who are heartbroken or can't find love. They'll often believe in horoscopes and fortune telling.
