If you could apply your native skepticism to your own beliefs, you would have a remarkable mind.
Or, if she could apply her native skepticism to her own beliefs, she would be remarkably crazy.
Her "skepticism" is such that if consistently applied, she wouldn't believe anything. That would be bad skepticism done wrong. She saves herself from this by applying her "skepticism" selectively, only to deny the conclusions of scientists when it suits her, and not so as to apply to her daily needs. If she did extend her principles to how she lives her life, she would, sure, be agnostic. On the other hand she wouldn't know how to tie her shoelaces.
