Via Slashdot: ABC News reports that a new study by Pew Internet finds that only one in six Internet users can differentiate between an advertisement and an unbiased search result. While several big search engines, such as Yahoo, Google and MSN, often tag their paid links with “sponsored site” or something of the like, the majority of Web users are still unable to make the distinction between paid and unbiased results. Despite this confusion, 92% of those surveyed feel confident in their Web searching capabilities.
