MBTI and making OCs

I decided to post this to this Reddit to see what the people here would say. 

For me here’s how I go through the character creation process: it starts out as a vague idea of the role they could play and what kind of character they could be, then I go through possible roles and personalities they could have based on my vague ideas. Once the role and personality is decided I start adding details. For me the hardest part is writing those long backstories and personality descriptions, but that’s most likely cause I’m bad at writing a large quantity in general. 

Another person told me they pick an appearance and from there they create the character.

I was wondering how it might be different for the different MBTI types when they create characters. Do you think the functions have any effect on it?

edit: to clarify I’m wondering how your mbti affects the way the you create characters not the your character’s mbti.
