Data Proves Amazon Reviews with “Free or Discounted Disclaimer” are Extremely Biased

Data Proves Amazon Reviews with “Free or Discounted Disclaimer” are Extremely Biased – we’re currently being hugged to death. Site is very slow to respond and we’re working on optimizing our technology to support the massive wave of traffic we’re getting.

After analyzing over 18 million reviews, our data continues to support our claims that the reviews with an incentive disclaimer (eg. “I received this product for free or at a discount in exchange for my honest and unbiased review”) are much more likely to be positive than reviewers who did not receive a discount.

Here’s our original blog post:

    I hate these kind of ‘reviews’ on Amazon. Seems they are suddenly
    everywhere. Some items I’ve looked at recently had about 15+ ‘incentivised’
    reviews out of a total of 20 or so. Crazy. One of the reasons I like Amazon
    is the customer review. I really hope they find a way to cut this crap out!

    The bias could me psychological. Meaning that if the reviewers are getting
    paid that makes their mood tward the product more positive.

    How do I become a Incentivized reviewer?

    Send me free shit please :)

  12. Justin Rofeh says:

    There are some biasing causes I can think of that they don’t mention in the
    video, none of which are intentional on the reviewer’s part:
    1. For these incentivized reviews, you don’t get paid until you prove that
    you wrote a review. This incentivizes you to review an item as quickly as
    possible — before you notice problems with it or before it breaks due to
    poor quality.
    2. When incentivized, practically everyone writes a review. On the other
    hand, non-incentivized reviewers are probably most likely to review items
    they are unhappy with. This means that by getting everyone to review,
    ratings are biased upwards.
    3. People who receive incentivized items might not have otherwise bought
    the item, and they could be less likely to have a specific need for the
    item. They might be less critical of the item because they will use it less
    and they don’t exactly know what they want from it in the first place.
    These points suggest that incentivized reviews are inherently biased.
