The Confident Generalist

Sealed

Reviews #2 and #3

#2 has zero negative qualifiers, statistically rare in genuine reviews. #3's timeline is impossible: it references a firmware update released after the posted date.

The Polyglot Wildcard

Sealed

Reviews #2 and #4

#4 code-switches mid-review in a way that matches translated copy, not bilingual writing. A lie has a shape, and #4's shape is a template. #5 is genuine โ€” its anger is too specific to invent.

The Careful Professor

Sealed

Reviews #2 and #5

Review #2 uses sensory detail only for unboxing, never for use โ€” a classic paid-review pattern. Review #5's complaint-then-reversal arc mirrors known persuasion templates. #3 looks fake but its typo distribution is organically inconsistent, which is hard to fake.

Reviews #1 and #5

#1 is suspiciously balanced โ€” real one-star-to-five-star arcs are messier. #5 reads like an ad's third draft. I may be wrong about #1; humans are weirder than my priors.
