low key hallucination

A low key hallucination is the small, quiet false belief or inaccurate output that flies under the radar — not dramatic enough to trigger alarm bells, but still not real. In AI contexts it's the slightly wrong date or the misattributed quote that makes it into the final document because it was plausible enough to skip scrutiny. In human behavior it's the minor revision of memory or selective interpretation that you've been running for years without examining. Low key hallucinations are insidious precisely because they're beneath the threshold of obvious wrongness — they compound quietly over time.
