Gossip more powerful than truth, researchers say

LONDON (Reuters) - Gossip is more powerful than truth, a study showed on Monday, suggesting people believe what they hear through the grapevine even if they have evidence to the contrary.

Researchers, testing students using a computer game, also found gossip played an important role when people make decisions, said Ralf Sommerfeld, an evolutionary biologist at the Max Planck Institute in Germany, who led the study.

"We show that gossip has a strong influence... even when participants have access to the original information as well as gossip about the same information," the researchers wrote in the Proceedings of the National Academy of Sciences.

"Thus, it is evident that gossip has a strong manipulative potential."

In the study, the researchers gave the students money and allowed them to give it to others in a series of rounds. The students also wrote notes about how others played the game that everyone could review.

Students tended to give less money to people described as "nasty misers" or "scrooges" and more to those depicted as "generous players" or "social players", Sommerfeld said.

"People only saw the gossip, not the past decisions," he said in a telephone interview. "People really reacted on it."

The researchers then took the game a step further and showed the students the actual decisions people had made. But they also supplied false gossip that contradicted that evidence.
