Well, if you don't know the difference between oil and energy, I would say that is a lack of knowledge, not a trick question.

Of course, our own quiz, which steers everyone to think of Peak Oil, is also a push-poll, by your definition.

Such problems hurt the reliabilty and thus the validity of outcomes drawn from the results.

Too bad there wasn't a control group made up of people provided the information and differences in terminology and then the quiz.
