Traditions exist to pass on learned knowledge and for social cohesion. Prior to widespread education, many local groups had to learn the same lessons and find a way to pass those on from person to person and generation to generation. Given that this also tended to coincide with societies not having the best grasp on reality (germ theory is not that old), the knowledge being passed on was often specious. But, it might also contain useful bits which worked.

For example some early societies would pack honey into a wound. Why? Fuck if they knew, but that was what the wise men said to do. It turns out that honey is a natural anti-septic and helps to prevent infection. They had no knowledge of this, but had built up a tradition around it, probably because it seemed to work. And so that got passed on.

The other aspect of traditions is social. When people do a thing together, they tend to bond and become willing to engage in more pro-social behaviors. It isn’t all that important what the activity it, so long as people do it together. The more people feel like they are part of the in-group, the more they will work to protect and sacrifice for that in-group.

Sure, a lot of traditions are complete crap. They are superstition wrapped in a “that’s the way we’ve always done it” attitude. But it’s important not to overlook their significance to a population. The Christian Church ran headlong into this time and again through European history as they sought to convert various groups. Those groups tended to hold on to old traditions and just blended them into Christianity. This resulted in a fairly fractured religious landscape, but the Church generally tolerated it, because trying to quash it led to too many problems. While stories of various Easter and Christmas traditions being Pagan in origin are likely apocryphal, there are echos of older religious beliefs hanging about.

It’s best to be careful when looking at a particular group’s traditions and calling them “backwards” or some other epitaph. Yes, they almost certainly have no basis in the scientific method. But, the value of those traditions to a people are very real. And so long as they are not harmful to others, you’re likely to do more harm trying to remove them than by simply allowing folks to just enjoy them.

Traditions evolved from superstition. If every time you do a thing, a thing you want happens, you keep doing that thing, creating the illusion of control.

OMG!!

YES!!!

Someone doesn’t know what OCD is

i would say ocd is the person having traditions and even that is wildly inaccurate

Traditions are peer pressure from dead people.

I feel it’s more like - we started doing it and never thought about it again

Many traditions like hand washing, public bathrooms, sewage systems and the cooking of food are literally about keeping people safe and alive.

This OCD is not only justified but why OCD is an essential part of what it means to be human.

We should do more traditional things… like living life without oil

True. Of course, there are plenty of good traditions. Birthday cakes. Halloween. Christmas. Sometimes OCD can be useful.

Traditions are experiments that worked.
