In the southwest we have a species of cactus known as jumping cactus. The common belief is that if you get close enough, it will reach out and stab you with its needles. Scienfically we know this doesn't happen. Cacti do not jump. Yet if you asked me 'who is less likely to be injured?' I would bet on the person who is staying 10ft away from the 'jumping' cactus because of their erroneous beliefs about the cactus. Luck certainly plays an outsized role in life. That said, it may not be a productive belief even if it is true.
