It used to be that you would do a search on a relevant subject and get blog posts, forums posts, and maybe a couple of relevant companies offering the product or service. (And if you wanted more information on said company you could give them a call and actually talk to a real person about said service) You could even trust amazon and yelp reviews. Now searches have been completely taken over by Forbes top 10 lists, random affiliate link click through aggregators that copy and paste each others work, review factories that will kill your competitors and boost your product stars, ect.... It seems like the internet has gotten soooo much harder to use, just because you have to wade through all the bullshit. It's no wonder people switch to reddit and lemmy style sites, in a way it mirrors a little what kind of information you used to be able to garner from the internet in it's early days. What do people do these days to find genuine information about products or services?
You’re asking about a pretty tough problem, and I don’t have the silver bullet for that one. However, I do have some tools that might help you out a bit. None of these tools are 100% reliable, so take everything with a grain of salt.
Fakespot and reviewmeta can help weeding out some of the junk reviews.
When I have a lot of text to go through, I just dump all of it on chatGPT or Bing and ask for a summary. It’s a language model after all, so it should be pretty good at this sort of thing. A horse won’t plow a field all by itself, but if you’re there to steer it, it will get the job done faster than you would.
When I’m looking for a good book to read, I’ll usually use the reviews of goodreads. Just skip all the 5-star reviews, because they are usually written by people who aren’t competent at reviewing books. Take all the the 1-4 star reviews dump them on your favorite LLM and let it look for frequently reoccurring complaints.
