Even when participants couldn’t find answers on the Internet, they still felt an increased self-assessment of how much knowledge they had. As a result, people may unintentionally exaggerate how much information they can recall on their own, the study said.

“It becomes easier to confuse your own knowledge with this external source,” said lead researcher Matthew Fisher of Yale University. “When people are truly on their own, they may be wildly inaccurate about how much they know and how dependent they are on the Internet.”

The study adds to existing research that suggests searching the Internet for information creates an increase in “cognitive self-esteem,” though not necessarily an increase in intelligence.
