Negative reviews increase trust

A product with 100% five-star reviews looks suspicious. Everyone knows it. A product with a 4.3 average and some critical reviews feels real.

Research consistently shows the sweet spot for purchase likelihood is between 4.2 and 4.5 stars. Higher than that and people start doubting the reviews are genuine. Lower than that and the product seems flawed.

The negative reviews do something the positive ones can't: they set expectations. "Runs a bit small" tells the next buyer to size up. "Battery lasts 6 hours not 8" sets a realistic expectation. Both of these reduce returns, which matters more than the marginal purchase the review might discourage.

Don't filter out negative reviews. Don't bury them. Show them alongside the positive ones with a helpful response from your team. The transparency converts better than the curation.
