Pop psychology’ books sometimes spout nonsense that is unsubstantiated by science. As part of my plan to rid the world of pop psychology I took 20 people in relationships and randomly assigned them to one of two groups. One group read the famous popular psychology book Women are from Bras and Men are from Penis, and the other read Marie Claire. The outcome variable was their relationship happiness after their assigned reading. Were people happier with their relationship after reading the pop psychology book (penis.sav)?
