>crowdsourced title is "Solving 2D Geometry Puzzles Using 3D Reasoning".
That attempted revision of the title is worse than the original clickbait title because it totally omits the "4D" topic. The 4D section starts around 18m50s and is 1/3rd of the content. The 2D/3D section was the prelude and motivation to prepare the viewer for the 4D section.
The "wisdom of the crowd" failed in this particular case.
Any attempted improvement on the title still needs to have "4D" somewhere in the title.
It hasn't failed. Not if you do what crowdsourcing requires and suggest a better replacement.
I agree that "Solving 2D geometry puzzles using 3D reasoning" does not fit the actual topic of the video, so I have replaced it with "Geometry puzzles with 4D analogies" for now – which is also not quite right, since the largest part of the video doesn't refer to any 4D concepts. I think it's, more generally, about puzzles that can be more easily solved by considering any other dimension, but it's harder to make a good title out of that.
Do you have another idea for an improvement?
yeah I find that annoying. If the video does not quickly answer the title yet uses the title to entice curiosity, then it's clickbait. I expect to find out what it makes it sad within minutes of clicking, not have to wait.
