Depends who you ask and how chatty they are, but in general probably correct - as it'd be a minority of humans who would speak at length given ten such questions to get through. (Whereas ChatGPT may not "value its time"...)

Maybe do the test again but instruct ChatGPT to keep its answers short? Not sure if that crosses a line and invalidates the test though - could be argued either way. The existing answers somewhat already curated by the prompt.
