My own anecdote. I hated frogs and disgusted by them. I don’t like frogs because I saw them chopped alive when I was a kid in a wet market in Asia, my mom brought me there to accompany her grocery buying. I think I was a first or second grader elementary.

Then I became a senior high schooler, and we had a biology class where we need to open up a frog. It was a group project.

After I opened up the frog, there’s no way for us to fix the frog anymore. Then I rip the frog even more apart, from skinning it completely to cutting it in many ways to the bone and skull to “learn more”.

My friends in my group were a bit horrified with what I did and they said I looked like I enjoyed it.

It was until a few days later it dawned on me like “how was I able to do that without any disgust, not only that, but with an interested curious somewhat happy look on my face? I am a psycho!”
