Psychology has the largest gap on YouTube between a title’s promise and a video’s contents, and we can put a number on that rather than assert it: this is one of the categories where our title-honesty measurement moves the most.
The pattern is familiar. “The psychology of why you procrastinate” is frequently a video about one study, described loosely, surrounded by advice that does not follow from it. The video is not lying. It simply promised a mechanism and delivered a mood.
The ranking on this shelf is by measured value density — how much of the runtime carries information rather than restatement — and entries where the title substantially oversells the contents are pushed down rather than featured. That is a judgement about the packaging, not about the presenter, and it is ours: we are not reporting what anyone else thinks of these videos.
One limit worth stating plainly. We measure how densely a video delivers what it says it will. We do not verify the science inside it, and a well-structured video about a study that did not replicate will still score well here. For that, read the study.

Gistil's own measurement. Not a YouTube rating, and not the channel's position. Ranking is ours; the videos belong to their channels.
How this ranking is decided
Every video here was measured on the same axes — how much of its runtime carries information, how much is padding, and the second at which it starts paying off. The order is by value density, not by views, recency or how much we liked the channel. What the numbers mean →
