Two Researchers Disagreed About Money and Happiness. So They Ran the Study Together.
The famous $75,000 plateau and the study that contradicted it were both partly right. Finding that out required something research almost never does: the two authors sat down and re-analysed the data jointly.
Renting is not throwing money away, but the real argument is stranger
Housing’s celebrated 7% return is almost all rental yield. Real capital gains run about 1% a year — and the variable that decides the answer is whether you actually invest the difference.
The sleep chart everyone copies has a footnote nobody reads
The age-by-age sleep chart is a compromise document, and the panels that wrote it said so. What the primary sources actually show about how much sleep you need.

The people who found the Blue Zones are quietly walking them back
Nicoya’s advantage inverted in forty years. Okinawa fell from 4th to 26th. And the researchers conceding this are the ones who identified the zones in the first place.
Your Myers-Briggs type is four coin flips in a trench coat
The MBTI measures four real traits with decent reliability, then discards most of what it measured by drawing a line through the middle of a bell curve.

When researchers finally put sensors on employees before and after a redesign, face-to-face interaction fell by about 70%. The study did not measure productivity — and after six decades of fit-outs, almost nothing has.

Learning Styles: The Experiment That Would Settle It Has Almost Never Been Run
