When one man was asked to agree with everything his wife said or asked him to do—”to agree with his wife’s every opinion and request without complaint,” to be exact—it took him a mere 12 days to lose his mind.
Researchers in New Zealand, tongues planted firmly in cheeks for the sake of an amusing Christmas issue of the British Medical Journal, decided to conduct an experiment (note: this is not a study) in which they instructed a husband to do the above (he was being agreeable and therefore the “happy” in this little trial), and did not instruct his wife—also, did not inform his wife of—anything (making her the “right”).
In 12 days, the dude's quality-of-life-o'meter had fallen from a 7 to a 3 (the wife's had risen from an 8 to an 8.5, obv), he confessed what had been going on to her, then promptly called up the researchers and waved the white flag.
It seems that being right, however, is a cause of happiness, and agreeing with what one disagrees with is a cause of unhappiness.
Or, in other words, duh.
