What are double-blind reviews in marketplaces?

In a double-blind peer review process, the provider and customer review each other at the end of a transaction but can only see the review they received once they’ve sent a review themselves. Many marketplaces utilize a double-blind review process to prevent feedback extortion. Famous examples are Airbnb, where both hosts and guests are prompted to review each other after a stay, and Uber, where drivers and passengers leave each other star-based reviews at the end of the ride.

Reviews are a great way to increase marketplace trust. Reputation plays a vital role in accessing revenue or services, encouraging users to strive to get good feedback. A marketplace can also use reviews and ratings to weed out bad and reward good behavior.

Here are a few examples where a form of double-blind review system might be used:

1. Freelance Service Platforms (like Upwork or Freelancer): In these platforms, when clients and freelancers rate each other after a project is completed, identities could be hidden during the review process. This approach can encourage more honest feedback and reduce bias.

2. Ride-Sharing Services (like Uber or Lyft): These platforms sometimes use a form of double-blind review where drivers and passengers rate each other, but the ratings are not revealed until both parties have submitted their feedback. This helps prevent retaliatory or influenced ratings.

3. Home Rental Services (like Airbnb): Similar to ride-sharing services, Airbnb can employ a double-blind review system where hosts and guests review each other, but the reviews are only made public after both sides have submitted their feedback, ensuring unbiased opinions.

4. Peer-to-Peer Selling Platforms (like eBay): In platforms where buyers and sellers rate each other, a double-blind system can be used to ensure that feedback is honest and not influenced by the other party’s review.

5. Professional Networking Sites (like LinkedIn): Although not a traditional marketplace, LinkedIn could implement a double-blind system for endorsing skills or giving recommendations, to add an extra layer of credibility and impartiality.

6. Online Dating Platforms: Some dating apps or websites might use a double-blind review mechanism for user feedback to maintain privacy and unbiased interactions.

In these examples, the double-blind review system helps maintain the integrity of the feedback process, encouraging more genuine and unbiased reviews, which are crucial for trust and reliability in marketplaces and service platforms.
