a lot of scientific studies are done that way. They take the
long way around though. I saw one recently. They measured
creativity and came up with metrics. They made choices based on
the videos they saw. Then they chose more videos they considered
creative and it matched the predictions of the model they came
up with. Well, duh. Same people making the same choices come up
with the same conclusions. It didn't predict anything. The only
difference is: They took notes.
