Introduction
Official UAP investigations rarely say a sighting is “93% likely to be a drone” or “87% likely to be extraterrestrial”. Instead, agencies such as NASA and the US Department of Defense’s All-domain Anomaly Resolution Office (AARO) usually rely on phrases like “likely”, “consistent with”, “probably”, “resolved as a balloon”, or “unresolved due to insufficient data”. That wording is deliberate. It reflects a core problem in UFO and UAP investigation: most reports do not contain enough reliable evidence to support exact statistical claims.
For AI-assisted UFO sighting investigation, this distinction matters. A numerical confidence score can look scientific while hiding major gaps in the underlying case file. Official investigators increasingly prefer calibrated language because sensor limitations, missing metadata, uncertain witness timing, and incomplete environmental context make precise probabilities difficult to justify. NASA’s independent UAP study repeatedly stressed that current analysis is limited by poor calibration and weak data quality rather than by a lack of speculative theories.

Why official reports prefer cautious wording
AARO and NASA are not avoiding percentages because they reject analysis or machine learning. They avoid them because UAP evidence chains are usually fragmented.
A typical unresolved sighting may contain only:
- A short infrared clip
- A witness account written later
- No verified distance estimate
- Missing camera metadata
- No radar confirmation
- No atmospheric measurements
- Uncertain timing
- Unknown sensor settings
Under those conditions, a precise percentage can create false confidence. NASA’s 2023 independent UAP report stated that analysis is currently “hampered by poor sensor calibration, the lack of multiple measurements, the lack of sensor metadata, and the lack of baseline data”. NASA Science Space That language reflects a scientific principle: uncertainty should remain visible. If the evidence is incomplete [space.com]space.comSpaceNASA UFO report finds no evidence of 'extraterrestrial…14 Sept 2023 — "At present, analysis of UAP data is hampered by poor senso…, the wording should show that incompleteness rather than compressing it into a neat-looking number.
This is why official reports often use layered phrasing such as:
- “Consistent with a balloon”
- “Likely airborne clutter”
- “Probably a commercial aircraft”
- “Undergoing analysis”
- “Unresolved”
- “Insufficient data for assessment”
Those categories communicate investigative status without implying mathematical precision that may not exist.
AARO’s language is designed around evidential thresholds
AARO’s published case summaries show a strong preference for categorical assessments over numerical probabilities. Public releases repeatedly classify incidents as “resolved as a balloon”, “closed as not anomalous”, or “unresolved”. [AARO]aaro.milAAROUAP ImageryThe United States European Command submitted a report of an unidentified anomalous phenomenon to the All-domain Anomaly Re…
That wording resembles intelligence analysis and aviation safety reporting more than consumer AI scoring systems. The focus is on whether the available evidence crosses a threshold for identification, not on assigning a cinematic certainty percentage.
This distinction becomes important in AI-assisted workflows. A machine-learning system may compare a new sighting against thousands of historical cases and conclude that it resembles known balloon behaviour. But resemblance is not identical to proof. Official investigators still need to consider:
- Atmospheric distortion
- Observer angle
- Classified platform limitations
- Missing contextual data
- Timing inconsistencies
- Alternative mundane explanations
AARO’s reports therefore tend to describe what the evidence is “consistent with” rather than claiming exact quantified certainty.

That approach also reduces the risk of misleading the public. A sentence saying “92% likely balloon” sounds definitive to non-specialists even when the underlying evidence may be weak.
NASA’s concern is not just UFOs but data quality itself
NASA’s UAP study was narrower and more methodological than many headlines suggested. The agency did not attempt to prove or disprove extraordinary claims. Instead, it examined how scientific investigation could improve if better data collection standards existed.
The report repeatedly returned to the same problem: most UAP reports are not scientifically robust datasets.

NASA highlighted several recurring weaknesses:
- Poorly calibrated sensors
- Missing metadata
- Lack of simultaneous measurements [science.nasa.gov]science.nasa.govNASA ScienceIndependent Study Team ReportAt present, analysis of UAP data is hampered by poor sensor calibration, the lack of multiple me…
- Inconsistent reporting standards
- Absence of baseline comparison data
- Short-duration events
- Compression artefacts in video footage
In practical terms, this means two analysts can view the same clip and reach different conclusions because key contextual information is absent.
For example, a bright object appearing to accelerate rapidly may actually involve:
- Camera zoom changes
- Auto-focus shifts
- Infrared blooming
- Parallax effects
- Tracking jitter
- Unknown range to target
Without full sensor telemetry and calibration information, assigning exact percentages becomes speculative. NASA explicitly warned that some apparent anomalies disappear once calibration and metadata analysis are applied correctly. [Wikisource]en.wikisource.orgResponses to Statement of TaskWikisourceNASA Unidentified Anomalous Phenomena: Independent…14 Oct 2023 — Indeed, several apparent UAP have been demonstrated to be s…
That has direct implications for AI-assisted UFO investigation systems. AI can help cluster similar cases, compare motion profiles, identify likely aircraft routes, or detect image artefacts, but its output remains constrained by input quality. Poor evidence does not become reliable simply because an algorithm processed it.
Exact percentages can distort public understanding
One reason official agencies avoid numerical UFO confidence scores is psychological rather than technical.
People naturally treat percentages as objective facts. A statement like “85% likely aircraft” feels authoritative even when the model behind it may never have been properly validated against comparable UAP cases.
This creates several communication risks:
Readers mistake estimates for proof
Most people do not interpret probabilities conservatively. A high number is often treated as near-certainty.
If a case file says “90% likely drone”, readers may stop asking important investigative questions:
- Were local drone records checked?
- Was the wind direction compatible?
- Did the object display impossible acceleration?
- Was the timestamp verified?
- Was the footage stabilised correctly?
The number can prematurely close inquiry.
Weak training data produces misleading certainty
AI systems require ground truth for calibration. UFO investigations rarely provide clean ground truth because many cases remain unresolved due to missing evidence rather than because they are extraordinary.
This creates a circular problem:
- Historical labels may themselves be uncertain
- Earlier investigators may have guessed incorrectly
- Many sightings were never fully resolved
- Sensor quality varies enormously between cases
An AI model trained on uncertain classifications can still generate very precise-looking numbers. Official investigators know that precision and reliability are not the same thing.
Public trust can collapse when percentages change
If one report labels a case “78% likely balloon” and later analysis reverses that conclusion, audiences may interpret the change as incompetence or concealment.
Cautious language avoids overcommitting before the evidence stabilises.
“Unresolved” does not mean “extraterrestrial”
Another reason AARO and NASA avoid dramatic percentages is that unresolved cases are often unresolved for ordinary reasons.
AARO has repeatedly stated that many unresolved reports lack sufficient data for confident identification rather than displaying confirmed extraordinary behaviour. The office has also argued that additional or higher-quality data would probably resolve many remaining incidents as ordinary objects or phenomena. [Reuters]reuters.comPentagon UFO report says most sightings 'ordinary objects' and phenomenaMost sightings were identified as ordinary objects or phenomena.

This distinction matters in public-facing AI systems.
An automated UFO investigation platform may flag a sighting as:
- “Insufficient data”
- “Weak aircraft correlation”
- “No matching satellite pass”
- “No atmospheric explanation identified”
That does not automatically elevate the case into something anomalous. It may simply mean the evidence quality is too low for confident classification.
Official wording attempts to preserve that distinction. Terms like “unresolved” or “under analysis” are intentionally narrower than sensational interpretations suggesting confirmation of unknown technology.
How calibrated language fits modern AI-assisted investigation
Careful wording is not a rejection of AI. In many ways, it is the opposite. Properly designed AI-assisted investigation systems benefit from calibrated language because it better reflects uncertainty management.
A structured modern workflow might include:
- Intake of witness and sensor data
- Timestamp validation
- Geospatial reconstruction
- Weather and atmospheric checks
- Satellite and launch correlation
- Flight traffic analysis
- Drone activity screening
- Astronomical object comparison
- Video artefact analysis
- Similar-case retrieval from historical databases
At each stage, uncertainty can increase or decrease. Exact percentages often hide that evolving process. Calibrated wording keeps the chain of reasoning visible.
For example:
- “Strongly consistent with Starlink flare geometry”
- “Likely aircraft based on ADS-B correlation”
- “Insufficient metadata for velocity estimate”
- “No verified radar corroboration”
- “Apparent acceleration may reflect parallax”
These statements tell the reader what investigators actually know and what remains uncertain.
That approach aligns closely with NASA’s call for “systematic data calibration” and improved metadata standards rather than sensational certainty claims.

Why this matters for future public UFO databases
As more civilian reporting systems adopt AI-assisted analysis, the pressure to produce simple confidence scores will increase. Public dashboards naturally encourage ranking systems, percentages, and automated labels because they are easy to visualise.
But official UAP investigations increasingly point in a different direction: richer uncertainty reporting instead of cleaner-looking certainty metrics.
A more responsible UFO case interface may therefore include:
- Evidence quality ratings
- Metadata completeness indicators
- Sensor reliability notes
- Competing explanation tiers
- Correlation strength summaries
- Confidence ranges rather than exact values
- Explicit unresolved categories
That structure helps prevent readers from mistaking incomplete evidence for definitive conclusions.
NASA’s UAP study repeatedly argued that the real bottleneck is not a lack of speculation but a lack of high-quality standardised data.
