I have this idea that if you read a description and see it as the best one, there's a high probability that that's your type.

However, this exactly coincides with confirmation bias, so it's a chicken vs egg problem. Am I really that type or am I just predisposed via cultural norms or some sort of complex to really badly want to be that type so I subconsciously block out all rational consideration for anything else?

What are your thoughts on this? Is someone who views a type as the best one deluded or is that their ego type?
