In my experience, making reviews easier to give causes the review quality and usefulness to go down. This happened when Netflix went from 5 stars to a simple like/dislike. I’m not sure why Amazon didn’t just block non-verified-purchaser reviews, increasing spammer costs significantly.
I suspect that Amazon reviews are going to be even less useful now. Especially given things like this:
> Amazon does not provide many specifics about how a product’s overall star rating is calculated, other than stating that it is not a simple average but instead uses “machine-learned models” that take into account factors such as how recent the rating or review is and whether it was a verified purchase or not.
