Claude's research mode is by far the worst one I've used, I consider it nearly useless. I cannot trust it specifically because Anthropic has a policy of refusing to use reddit for anything, whether it be as a research source or in claude chrome.

Reddit may not be the greatest source for hard science, but for things like "tell me what shoes people are finding helpful for their plantar fasciitis" I appreciate reddit's anecdata of reddit over every other source.
