Mark: when you were a Psych grad student, did anyone complain about the wording of the paper ? item 23 gives instructions (which must be followed). item 1 instructs that item 23 must only be read until the whole paper has been read. The Instruction at the top of the paper makes these two instructions self contradictory.

It seems impossible for anyone to have obtained full marks as they must have ignored some part of the paper!
