MBTI Type Questions? Curious

[Nef]

I don't know an incredible amount about MBTI typing, however I had a few questions and was hoping people could illuminate potential answers if possible? I realise in advance that some of these questions may sound silly.

I'm somewhere between INFJ and ISFJ depending on what test.

Can the MBTI type testing come up with incorrect type answers due to personality defects, depression, etc?

Can the MBTI type testing be questioned if someone answers the questions/options honestly the best you can however that person doesn't live their ideal lifestyle. (I believe this could come under depression perhaps?)

Does childhood experiences shape what your MBTI type is? Or is your personality type depicted in your genetic makeup?

Can your MBTI type change if you perchance go through a life crisis or attempt to re-invent yourself?

I was also going to question the fine line between introvert and extrovert as well. However I'm not sure exactly what I'm asking.

Please, thank you!

Yes the tests can give incorrect answers, you should never trust the results without checking what the results(the type you got and other types) mean and evaluate whether the results were correct. Even if you try to answer the question correctly, there are all sorts of biases.

Genes certainly have alot to do with type and it seems that early childhood environment has also something to do with it.

Crisis grows you, but you wont change your type. Crisis usually comes due to problems with the functions that are less developed and makes those functions stronger.
