How do people make decisions?

Sub-research questions:
1.) Does conforming/nonconforming affect your opinion?
2.) Do your ethics change who you are? Or what you choose?
3.) How do people shape their ethics?

What I already know about this topic-
I know that if you were to follow with others, or conform, then that could affect your future, especially if you end up successful, or even happy. If you were to go your own way, or not conform, you could be praised or scolded for that decision. There are multiple ethics in the world today, especially with religions, and that could affect whether or not you do something that someone else is doing. You could be born with specific morals, ethics, or opinions but those could be changed with what you see or hear. Even magazines/TV can change that.
