Archaeologists now propose that pottery emerged not from intentional experimentation but from accidental firing during wildfires — the "natural kiln hypothesis" suggesting humans simply noticed what happened when clay sat in the wrong place during the wrong event.
This explanation tells you something precise about how academic fields cycle through confidence and doubt about human agency. In the early 1900s, pottery origin stories centered on accident. A clay-lined pit caught fire, someone observed the result, and invention happened to people rather than through them.
This framework dominated until the 1960s and 1970s, when archaeologists shifted dramatically toward models of intentional experimentation and purposeful craft development. The difference was not fresh evidence — it was a shift in what seemed plausible to assume about past consciousness.
What repeats is structural. Each time a field loses confidence in reconstructing human intention from incomplete evidence, it defaults to technological determinism. Fire domestication follows the same arc, as does agriculture, metallurgy. Archaeologists propose that people discovered these things because circumstances forced discovery. The environment arranged itself into teaching moments. This is not speculation emerging from better data. It's the field swinging between two poles of discomfort.
Chance plus proximity is not causation.
Either we reconstruct intention confidently and risk projecting ourselves backward onto people we cannot interview, or we outsource the work to accident and avoid that projection entirely, at the cost of explaining why humans did anything deliberately at all. The hypothesis will either rest on reconstructed evidence specific to fire management in early settlements, or it won't. If the natural kiln hypothesis requires only the abstract possibility of wildfire plus the existence of clay, it's a placeholder. A way of signaling uncertainty while sounding like explanation. Chance plus proximity is not causation. Intention is what separates an accident you notice from an accident you've learned nothing from.
