Online reviews have become an essential tool for consumers to make informed decisions about purchases, restaurants, and movies. However, not all reviews can be trusted, as there are both honest and deceptive ones. Fake reviews can harm a product's reputation, with negative ones potentially submitted by competitors and positive ones posted by individuals with a financial interest. Companies like Amazon are using artificial intelligence (AI) to identify and prevent fraudulent reviews. Consumers can protect themselves by trusting their instincts, paying attention to language and tone, validating reviewers, and looking for patterns in reviews. AI technology can help websites flag potential fake reviews, maintaining the credibility of their review systems.
