How can investigators reliably tell novel, unexplained phenomena apart from equipment-induced signals and confident but flawed human reports when all they have are noisy sensors and fallible memories?

UAP Investigations

U.S. agencies are investigating UAP through data collection, standardized reporting, scientific analysis, and case resolution. AARO says many cases have been identified as balloons, birds, drones, satellites, or aircraft, while a small remainder may still warrant analysis. NASA’s study treated UAP as observations not yet identified as aircraft or known natural phenomena and focused on improving the quality and availability of data, rather than concluding that the observations are extraterrestrial. Skeptical analyses argue that the available evidence—often videos, photographs, and testimony—does not demonstrate alien visitation and that many apparent anomalies result from ordinary objects, sensor effects, or misperception. Dissenting UAP commentators argue that some cases, including military observations, may not be adequately explained by conventional reconstructions and justify more open-minded, data-rich investigation. The main disagreement is how much evidentiary weight to give unresolved reports and witness testimony.

Sensor artifacts

A sensor artifact is an apparent feature introduced by equipment, transmission, processing, or analysis rather than by the underlying phenomenon. Examples include dust spots, diffraction effects, compression, glare, and statistical distortions. Research shows artifacts can materially affect interpretation across fields: they can distort astrophysical measurements, neural recordings, image segmentation, and even automated object detection. In UAP cases, mainstream scientific and skeptical analyses emphasize calibration, missing metadata, parallax, glare, gimbal motion, and optical focus as possible explanations for apparently unusual motion or shape. The main disagreement is whether a given observation has been adequately explained as an artifact or remains genuinely anomalous because the available measurements are incomplete or ambiguous.

False memory and perception

Research describes memory as a reconstructive process that can be affected by misinformation, emotion, physiological responses, and source-monitoring errors. False memories may arise through semantic, perceptual, or associative similarities. Neuroscience studies find overlap between true and false remembering, while also identifying differences in sensory or frontal-cortex activity and in the processes involved in conceptual versus perceptual false recognition. Recent reanalyses of the ‘Lost in the Mall’ paradigm argue that investigator judgments may overestimate fully formed false memories; participants often recalled few suggested details and sometimes described potentially genuine experiences instead. The main disagreement is not whether memory can be inaccurate, but how readily people can develop confident memories for wholly fictional events and how valid common experimental measures are.
