Silly example from my life. When I was three, I liked a girl named Katy in my Sunday school class. My greatest fear was that someone else would know. So I decided that I would be mean to Katy. I also realized that if I treated her differently, someone might read into that that I liked her. So I started treating all the girls in my Sunday school class horribly. And kept it going (consistency bias) until I was twelve. There were so many times that I wasn't even sure myself if I liked or hated girls, since I always said I hated them, even though I had crushes on most of the ones I knew.
