If one is presented two questions, - Bill plays jazz - Bill is an accountant and plays jazz, is there an implied "Bill is not an accountant", created by our flawed minds, in the first question? This could explain the rankings.

There was an implied "Bill is not an accountant" in the way I read it initially, and I failed to notice my confusion until it was too late.

So in answer to your question, that has now happened at least once.

I, too, was worried about this at first, but you'll find that http://lesswrong.com/lw/jj/conjunction_controversy_or_how_they_nail_it_down/ contains a thorough examination of the research on the conjunction fallacy, much of which involves eliminating the possibility of this error in numerous ways.
