I’ve always thought psychological experiments were weird, but this one deserves some kind of recruitment award.
Would you agree to have a pleasant conversation with your spouse in front of some researchers? What about if you first had to let a machine make tiny little blisters on your arm? What about if you then had to argue with your spouse, after getting more tiny blisters? And then if you had to let someone monitor your blisters’ healing for two weeks?
For $2,000, would you do it?
All of this apparently proves that happier married people are healthier. But I think what it really says is that among people who will agree to do almost anything for money, the ones who are more happily married are healthier.
