Has anyone ever studied the psychology behind a person's "Favorite Pokemon" and why people psychologically choose for a specific Pokemon to be there favorite and what that ends up meaning for them as a person?
Is it so far fetched to think that people who select the same Pokemon as their favorite are more likely to share other personality traits, mannerism, likes, dislikes, etc.?

This is approaching a weird "Pokemon but Horoscopes" concept which I'm not sure has yet to be fleshed out.
