Am I not, are we not?

[Rachel Adams]

Hello.
Is it wrong to say that the forms 'aren't,' and 'isn't are more common than 'Am I not?' 'Is she not?' 'Are we not'?
'I am not. Aren't I?'
'She is not. Isn't she?'
'We are not. Aren't we?'

I am confused. Would you mind explaining your question?

I am confused. Would you mind explaining your question?

Yes, of course. I was asking if aren't I, isn't he, she, it, etc are more common than am I not? Is she not?

 

[Rachel Adams]

It is not.

When would a native speaker use less common forms such as 'Am I not?' 'Is she/he not?' 'Are we not?'

 

[Tarheel]

Yes, of course. I was asking if "aren't I", "isn't he", "isn't she", "isn't it", etc are more common than "am I not?" or "Is she not?"

Yes, I think so.

In more formal situations and/or for emphasis.

Can the same be said about 'Can I not?', 'Will I not?', 'Should I not?' and other English verbs?
