An astute observation from MeFi member JimmyJames:
Next time people ask why sociology is important, I'm going to show them this video.
On its own, when you see one person slip, you automatically assume that person slipped, was clumsy or not playing attention. But when you look at the aggregate, you realize that the failure isn't on the individual at all, rather the structures that cause certain people to fail with almost no fault of their own. And yet, without this data, they will very quickly ascribe the mistake to themselves.
