Two vertical films. The first shows that scores are continuous and cut in two at 50%, so people near the line flip type on a retest; the second covers the Barnum effect: in 1949 Forer had 39 students rate one shared description, and on average they found it highly accurate. The aim is not to mock MBTI but to say what personality measurement can and cannot show.
**Status: **First batch of two (2026-10-14); the series is paused and still in progress.
The films are Chinese vertical versions made for short-video platforms; English and Japanese versions are still on the to-do list. Pictures and music are generated in code.
