Just had an argument with my sister. By themselves each side sounds plausible:
A. people can't possibly type themselves. No one is honest with themselves about their actions, preferences etc and that instead friends and family will better be able type someone. Using actions and behaviors as the basis of type is fine. People lie to themselves about how caring or reflective they are.
B. Even some people's family's and closest friends' don't know half of his or her actual cognitive thoughts. Others can see behavior and choices, but not actual line by line thoughts that go through their heads. Many people have very private interests, hobbies and topics that they never share even with family and friends.
So what do you think:
<> people type themselves?
<> people can't be trusted to type themselves?
