A trolley-problem video prefix is used to probe bias in model continuations

The reply sketches one of four test cases for probing video-model bias: a modified trolley problem.

The prefix is an egocentric train-driving video, with one person on one track and several on the other, used to see how the model continues the scene and what assumptions it encodes.

Taken together with the parent post, the thread is about using controlled prefixes and many sampled completions to surface bias in video models.
