Goalposts

I disagree, I think the hard part of the Turing test is passing well constructed interrogations that check for comprehension, deduction, improvisation, etc. For example you teach the subject a novel game, ask them to play it, then change the rules, or you describe a situation, describe changes and activities and interrogate them on subsequent states. Essentially check for problem solving, deduction, etc, things that require actual intelligence.

You can't proxy a test for intelligence to other attributes, like quirks or personality. You have to actually test for the attribute in question.
