(Also, how open are you to being dissuaded from it? I'm always open to new information, so if you're concerned about me embarrassing myself in public with these ideas, enlighten me, by all means.)

Two examples come to mind for me.

• Astrology. I don't think the positions of the stars have any actual bearing on people's destinies, but there are definite traits that seem common to the individual signs, across cultures and eras. Perhaps there's a natural cycle of some sort that affects our collective psychology or even biochemistry and we misattribute zodiac stereotypes because it happens to align with the celestial "movements"?

• Graphology. The notion that particular characteristics or tendencies could be expressed in something like handwriting doesn't sound unreasonable to me. Our minds physically express many things in our body language, and I could see how handwriting might essentially be an extension of that, or another translation.

Of course, this could just be self-selection and delusion, but these are likely complex issues and there's still quite a lot we do not understand.
