Internet users do not know the best ways to find quality information on the web, according to a survey of nearly 3,000 American adults conducted by the Pew Internet & American Life Project. The findings show that two-thirds of adults begin their internet search for health information by accessing a search engine. And, in a downward trend from survey results conducted in 2001, three-quarters of internet users do not check the source or the date of the information. The new survey was a follow-up from Pew's 2001 national survey, "Vital Decisions: How Internet Users Decide What Information to Trust When They or Their Loved Ones Are Sick," which found that more than half of internet users, or approximately 73 million Americans, use the internet when seeking health information. The Pew Internet Project produces reports that explore the social impact of the internet.
