Teacher Tests Claude: Confident but Misses the Point in Long-Text Analysis
RampantInanity · reddit · 2026-07-31
A master's student and teacher shared a revealing test of Claude, noting that while it is exceptionally confident in its writing analysis, its actual performance is poor and highly misleading.
The author found that despite its large context window, Claude fails to grasp the context of longer texts (around 50 pages). It consistently misses the forest for the trees, getting hung up on minor points and losing the logical connection between a thesis and its supporting paragraphs.
Its feedback mechanism is even more flawed. Claude once bombastically claimed a sentence "detonated" the thesis, but this was only true if you read the second half of the sentence in isolation. The author warns that users outside their domain of expertise can easily be tricked by the model's unwavering confidence into accepting poor or incorrect analysis as valid.
