Before, during or after an important event, we often perform symbolic behaviours, or rituals, that are of different shapes and forms. These acts often look superstitious and irrational. Many are practised in either a communal setting or in complete solitude.

The desired outcomes for these rituals can be to remove anxiety, boost confidence, or for improved performance in a competition. The surprising thing is that rituals are more rational and scientific than they appear on the surface, and are also effective.
