Online shoppers often turn to reviews and customer feedback for help, but even these are unreliable sources. Sometimes people post negative reviews just to be spiteful or angry.

The lack of insightful information online forces shoppers to rely on the information they find elsewhere, but this can lead to misinformation and incorrect purchase decisions.
