This is the online shopping mistake you need to stop making now
[A] Online reviews can be highly entertaining, and theoretically, they should be helping us make good decisions about what to spend our money on. As it turns out, however, they do help us make decisions – just not necessarily the best ones, according to a new study published in Psychological Science.
[B] Specifically, the study reveals that we are more inclined to buy a product that has more reviews than a product that has less, even if the product with more reviews has lower ratings. That inclination is so strong, in fact, that given a choice between two products that have equally bad reviews, we're still inclined to buy the one with more reviews – despite that the higher number of reviews means that the product is even more likely to be bad.
[C] Dr. Powell and his colleagues asked several hundred people to look at a series of cell phone cases, presented in pairs along with the average user rating and number of reviews for each case, and then indicate which case they would be more inclined to purchase. Across the board, for each pair, the participants tended to choose the case that had more reviews, rather than better reviews.
[D] The researchers concluded that our brains are so wired to gravitate (被吸引) toward what we see others doing that we find ourselves unable to see beyond that to make meaningful statistical inferences. "We found that people were biased toward choosing to purchase more popular products and that this sometimes led them to make very poor decisions," he explains in a press release by the Association for Psychological Science.
[E] "Consumers try to use information about other people's experiences to make good choices, and retailers have an incentive to steer consumers toward products they will be satisfied with," Dr. Powell added. "Our data suggest that retailers might need to rethink how reviews are presented and consumers might need to do more to educate themselves about how to use reviews to guide their choices." That includes absorbing the notion that a larger number of reviews is not a reliable indicator of a product's quality.
1. Humans are naturally drawn to follow what others are doing, which can impair their judgment.
2. In an experiment, participants repeatedly chose phone cases with a higher number of reviews over those with better ratings.
3. Retailers may need to change how they display reviews, and consumers should learn to interpret them more critically.
4. Online reviews are meant to help consumers make informed decisions, but they don't always lead to the best choices.
5. People tend to choose products with more reviews, even if those products have lower ratings.
