@bkcunningham I mean the original reason the superstitions were created and passed down. Most people who follow the superstitions might be just buying into them without knowing why.
Rocking a chair with your foot can easily make you ustable and you can lose balance and fall down and hurt yourself.
The ladder is obvious, people up above ar working and could drop something on your head, or God forbid you knock into the ladder you could make it unstable, and a person on it might fall.
We don’t do up the baby nursery, because in years past many pregnancies went wrong and infant mortality was high, so waiting for the baby to seem very stable saved the grieving mother from staring at an empty room made for baby with baby things all around.
Umbrellas opened indoors are more likely to poke someone else in the room.
Having a ritual that brings ou luck reinforces routine and means someone is less likely to forget an important step when preparing for something.
Superstition is a little different than old wives tale and a little different than a religious belief, but they are all related. Religion also employs fear to get people to do what is supposedly best for them. It also has routines to bring us comfort.
People who are less likely to ask why, or who may not be so bright, just follow along, others are more analytical. Some people are easily willing to believe the bbogie man or God or the Fates will get them, others want to know the logic behind something.
Of course there are some superstitions that are seem out of nowhere and maybe have no logic, I am not saying they all make sense or anything like that.
