I have noticed on a lot of Amazon products that the review distribution will look something like this:
5 star: 75%
4 stars: 6%
3 stars: 2%
2 stars: 1%
1 star: 16%
It seems odd to me that a product would get a high percentage of top ratings, then drop off through the lower ratings, but then suddenly there is a surge of lowest-level ratings. What causes these to be so polarized? I have some theories:
- The 5-star reviews are loaded with fakes (although even so, the profile would still be bimodal).
- The most dissatisfied people are the ones most likely to express their frustration through reviews.
- The profile represents poor quality control for the product–it either works perfectly or fails miserably.
Seems like this would make for an interesting grad thesis.
