It is often claimed that ratings and reviews are increasingly losing appeal among online retailers in favor of more trendy, state-of-the-art ecommerce applications that tap on the “social graph” to deliver “instant personalization.” Trust is often cited as one of the primary reasons that ratings and reviews are becoming less relevant – there is limited value in anecdotes and numerical ratings from anonymous reviewers, whose authenticity cannot be verified. Furthermore, just like customer testimonials, consumer reviews are almost always cherry-picked to favor positive reviews. Ratings and reviews vendors, such as Bazaarvoice and PowerReviews, allow online retailers to moderate user-generated content as they wish.
However, even if we eliminate the trust issue, they suffer from another important drawback: reliability. At the risk of unduly dwelling into semantics, there is a subtle but important distinction between trust and reliability. The former relates to honesty and integrity (“Do you mean what you say?”), while the latter relates to usefulness and value (“Even if you mean what you say, do you know what you are talking about?”).
Consider the following arguments against the reliability of ratings and reviews:
By design, reviewers are chosen from an unrepresentative sample, resulting in selection bias. Ordinarily, there is no incentive to write reviews; the process is cumbersome, the effort required is onerous, and there is no instant gratification or reward. The only people who would normally write reviews are those motivated by emotional or irrational reactions so extreme that they warrant a public sharing of experiences. Consumers are more motivated to share their opinions on things that they find extremely good or bad, and they avoid broadcasting banal and uninteresting trivia. For a consumer doing purchase planning, however, this polar distribution of reviews is unhelpful because mediocre reviews (which are also important information) are underrepresented. Worst of all, the remaining sample of reviews is often not a product of objectivity, rationality, and good consumer sense.
The typical consumer is not unaffected by the bandwagon effect. Herd instinct is a prevalent, subconscious trait. It gives people a sense of certainty and safety to know that whatever they do or say has some sort of alignment with prevalent practice. Thus, if consumers are given the liberty to view what others have said in their ratings and reviews (which they are), they are likely to be swayed by others, despite originally having divergent views, especially if others are perceived to be more well-reasoned or convincing in their views (i.e. authority bias). This is a common crowdsourcing pitfall: we are heavily influenced by the behavior of the crowd. Even if we usually avoid the majority view, we cannot be sure that we are not subconsciously or deliberately acting against the majority’s behavior in an attempt to artificially differentiate ourselves.
Consumers suffer from choice-supportive bias and post-purchase rationalization. Consumers are prone to justifying purchase decisions even though they may realize that the decisions were poor. This behavior is not surprising, since acknowledging the imprudence or redundancy of a purchase implies that one is an incompetent and/or irrational shopper. Such post-purchase rationalization is further magnified if the purchase was in fact well-researched, expensive, or stubbornly made against the advice of others. People often want to think that sunk cost – especially if it is great – has some sort of benefit or intangible reward. Some examples include pursuing expensive degrees, going on mediocre premium holidays, and buying overpriced clothes.
Reviewers may be in a position of conflict of interest. Online retailers commonly solicit reviews from their customers to help kick-start or encourage content creation on their websites. Keeping in mind the original lack of incentive to write reviews, online retailers remedy the situation by offering discounts, coupons, and special offers to entice participation (a practice adopted from how businesses conduct focus groups perhaps). As a result, reviewers are bestowed with the moral obligation to say favorable things using thesaurus-level, meticulously-manicured language. The resultant artificial form of communication is likely to be abhorred by consumers looking for genuine data points to guide their purchase decision-making process.
At its root, the concept of ratings and reviews has fundamental structural issues, due in part to technological limitations and commercial reasons. Ratings and reviews are an integral, consumerist component of the purchase decision-making process; their purpose is to provide consumers with adequate, trusted, and reliable information. They have not been the perfect solution but have perhaps been the best we have so far. Now, with the prevalence of portable social identities, mobile internet, and broadband internet, perhaps it is timely to adopt a new paradigm, a new strategy that incorporates a more targeted, meaningful “social” element to drive consumerism.
Of course, new social commerce solutions are not foolproof. However, given the vast potential of social commerce, it is ultimately not a poor decision to explore how it can possibly transform consumer experience, multiply sales, and build brand loyalty.
