Here's a good thing about the Internet that also can be a bad thing: Online information makes research for school easy . . . and risky. (By the way, that's called a paradox -- a statement that seems to contradicts itself. It's pronounced pa-RAH-docks.) Two new campus studies cite the hazards of web research for homework, business use, medical tips or other purposes. The takeaway: Check carefully to assure sources are credible and reliable.

Although a prominent spot in search engine results doesn't automatically signal believability, Northwestern University researchers found that a majority of college freshmen click on the first search result no matter where it's from. More than 25 of the 102 students surveyed said they always choose the top result. "In some cases, the respondent regarded the search engine as the relevant entity for which to evaluate trustworthiness, rather than the website that contained the information," says the Illinois university's study, published in the International Journal of Communication.

In a University of Southern California study issued two weeks ago, large percentages of Internet users say they distrust online information. Sixty-one percent believe half or less of online information is reliable -- the lowest level since the Digital Future Project began nine years ago at the Annenberg School for Communication and Journalism at the Los Angeles university. Fourteen percent of respondents say only a small portion or none of the information online is reliable -- a percentage that has grown for the past three years.
Skepticism may flow partly from the growing number of sites or "articles" posted by companies pushing products, services or promoting online content. As the video below suggests, some health or fitness advice comes from businesses that are aren't necessarily as reliable as sites compiled by a government agency, hospital or medical association.
