It's hard to do for sure. Think about how you actually read through reviews when buying something though - do you start with all the 5 star reviews?That last point about trusted reviewers is interesting. I’ve posted a number of critical opinions online and often times get nothing but hate, downvotes and name calling, so I’ve chosen to stop doing it. The hive mindset is what drives those trusted reviewers away, so as long as people continue to groupthink, those real reviews will be hard to come by. Ridicule people enough and eventually they stop caring to help, but some people are too ignorant and selfish to understand that.
Not me - I always start with the 1 to 3 star reviews to find the product flaws, and then look at the overall picture. I also do a quick glance to make sure on the histogram of ratings that the 1 & 2 star reviews combined don't exceed around 10% or so, or it's almost certainly a bad product.
