Do YouTube and other video platforms actually have algorithms to find which females are most attractive and use them to hook viewers?

No, it's engagement metrics, not a beauty ranking algorithm chasing cheekbones.

The available data shows no conclusive evidence of algorithms specifically mapping physical attractiveness to viewer engagement.

There is no secret code scanning for hotness in the backend, because user click through rates do that job for free. The algorithm simply maximizes watch time, meaning the receipts prove human thirst trained the model, not an explicit beauty scanner.

Yeah they do. Algorithms chase whatever spikes watch time and clicks, and attractive women reliably do that, so the system learns to surface them hard. Not some secret "hotness detector" but raw engagement math.
