We recently established a successful Useful Concepts Repository. It got me thinking about all the useless or actively harmful concepts I had carried around for in some cases most of my life before seeing them for what they were. Then it occurred to me that I probably still have some poisonous concepts lurking in my mind, and I thought creating this thread might be one way to discover what they are.
I'll start us off with one simple example: The Bohr model of the atom as it is taught in school is a dangerous thing to keep in your head for too long. I graduated from high school believing that it was basically a correct physical representation of atoms. (And I went to a *good* high school.) Some may say that the Bohr model serves a useful role as a lie-to-children to bridge understanding to the true physics, but if so, why do so many adults still think atoms look like concentric circular orbits of electrons around a nucleus?
There's one hallmark of truly bad concepts: they actively work against correct induction. Thinking in terms of the Bohr model actively prevents you from understanding molecular bonding and, really, everything about how an atom can serve as a functional piece of a real thing like a protein or a diamond.
Bad concepts don't have to be scientific. Religion is held to be a pretty harmful concept around here. There are certain political theories which might qualify, except I expect that one man's harmful political concept is another man's core value system, so as usual we should probably stay away from politics. But I welcome input as fuzzy as common folk advice you receive that turned out to be really costly.
These aren't the only two possibilities. Lots of important aspects of the world are socially constructed. There's no objective truth about the owner of a given plot of land, but it's not purely subjective either -- and if you don't believe me, try explaining it to the judge if you are arrested for trespassing.
Social norms about morality are constructed socially, and are not simply the preferences or feelings of any particular individual. It's perfectly coherent for somebody to say "society believes X is immoral but I don't personally think it's wrong". I think it's even coherent for somebody to say "X is immoral but I intend to do it anyway."
You're sneaking in connotations. "Morality" has a much stronger connotation than "things that other people think are bad for me to do." You can't simply define the word to mean something convenient, because the connotations won't go away. Morality is definitely not understood generally to be a social construct. Is that social construct the actual thing many people are in reality imagining when they talk about morality? Quite possibly. But those same people would tend to disagree with you if you made that claim to them; they would say th... (read more)
