I think this sheds some light on why “wive’s tales” are so prevalent even to this day. A lot of us know they aren’t true but there are many other people out in the world continuing to assert them as truth causing the myths to perpetuate.
I’ve also noticed that during this election cycle, the candidates say a lot of the same things over and over (regardless of truth). I think this sheds some light on why that happens. The idea is that if you hear the same thing enough times, your brain believes it to be true.
