Since the launch of Project Ozma in 1960, SETI researchers have searched for extraterrestrial intelligence, while UFO researchers have argued that evidence of non-human intelligence may already exist on Earth. Despite this apparent overlap, the two fields remained largely separate for decades. That divide is now under pressure. Since the 2022 Congressional hearings, whistleblower claims, government reports, and growing academic engagement have pushed unidentified anomalous phenomena (UAP) from the margins into political and scientific debate. While their nature remains contested, this talk examines what their changing status reveals about the social organization of knowledge. Why did UAP become a scientific taboo, and why are some governments less willing to sustain it? The answer may illuminate how societies respond to evidence of other capable minds, whether extraterrestrial or artificial.
