> archaeologists say it "isn't possible to do X with Y" Do they? Many people use "everyone said X was impossible, but I found out how to do X!" as a framing device to tell their story, but whenever I investigate one of these I generally find that it isn't strictly, err, true. People weren't saying "X is impossible" so much as "we think tribe T didn't know how to do X so this artifact was probably imported" or something similarly hedged. The new information is genuine, but the narrative is just storytelling.
