Description
Shin, writing alone in 2026, tested whether people with major depression make more consistent choices than healthy peers. Healthy people often break simple ranking logic, preferring A over B, B over C, and yet C over A. Such loops may show flexible thinking rather than error.
Twenty-one patients and twenty-one matched controls made forced choices across six kinds of images, from objects to drawn faces. A new count, called tricksters, measured how far each set of choices sat from a clean ranking. Choices that involved tricksters took longer, which backs the measure. Patients showed far fewer tricksters, above all for face images. The author reads this strict ranking as a sign of rigid thought in depression.
