Which one of these boxes is not like the others? Explain your answer.
So far, out of the people I have asked (before my lab actually started):
Undergrad - 1 answer which was wrong (did not answer the question)
Brand New Grad Student - 2 answers both of which were wrong (did not answer the question)
Finishing Masters Student - 3 answers all correct
Finishing PhD Student - ~6 answers although needed to be coaxed to actually answer the question
My conclusions are that the more education you have the more you over think the question.
