Misidentification

Misidentification is the fate of the overwhelming majority of investigated UFO reports — somewhere around 90-95% by most serious researchers' own estimates, a figure both mainstream skeptics and rigorous ufologists broadly agree on even though they disagree sharply about almost everything else in the field. The list of everyday causes is long and well-documented: the planet Venus and other bright planets low on the horizon, conventional aircraft (particularly at unusual angles or in formation), weather and research balloons, satellites and Starlink trains, birds catching sunlight at odd angles, Chinese lanterns, and simple camera or sensor artifacts like lens flare and bokeh orbs. What keeps the topic genuinely contentious, rather than settled by that near-universal agreement on the percentage, is entirely about the small residual fraction left over once every available conventional explanation has been checked and ruled out — the actual debate in serious ufology isn't "are most UFO reports misidentification" (nearly everyone agrees they are) but "does anything real remain in the unexplained residue, and if so, what is it." AARO's own public case statistics, and Project Blue Book's historical 701 unexplained cases out of 12,618, both structurally reflect this same misidentification-heavy pattern with a genuine unexplained remainder.
