Contrasts and interactions redux: Five easy pieces

This reply to Abelson (this issue) and Petty, Fabrigar, Wegener, and Priester (this issue) is couched within the framework of five basic principles advising that we (1) hang on to what we predicted long enough to test it (Tarzan's leap), (2) be wary of beguiling statistical designs that may not address the question of interest (the Sirens' song), (3) not allow well-worn habits of thinking to ensnare our perceptions (Lavoisier's crease), (4) weigh the possibility of more than one correct hypothesis (the dayyan's decree), and (5) not confuse unplanned with planned contrasts (the archer's aim).
