Bad
news becomes hysteria in crowds, new research shows

News
stories about terrorism, disease outbreaks, natural disasters, and other
potential threats become increasingly negative, inaccurate and hysterical when
passed from person to person, according to new research by the University of
Warwick.
Led
by Professor Thomas Hills in Warwick's Department of Psychology, the study
finds that even drawing the public's attention to unbiased, neutral facts does
not mitigate this contagion of panic.
This
is the first research ever to investigate the impact of dread on the social
amplification of threat, and to examine the re-exposure of balanced information
on the social diffusion of messages.
The
results have important implications for contemporary society -- with the
constant proliferation of news stories (both legitimate and fake), rumours,
retweets and messages across social media.
The researchers analysed 154 participants on social media. They were split into 14 chains of 8 people, with the first person in each chain reading balanced, factual news articles, and writing a message to the next person about the story, the recipient writing a new message for the next person, and so on.
The
sixth person in each chain was given the message from the previous person,
alongside the original neutral news story.
In
every chain, stories about dreaded topics became increasingly more negative,
and biased toward panic and fear as it was passed from person to person -- and
crucially, this effect was not mitigated when the original unbiased facts were
reintroduced.
The
original neutral information had virtually no effect on reducing people's
increasingly negative outlook.
Professor
Thomas Hills from the University of Warwick's Department of Psychology,
commented:
"Society
is an amplifier for risk. This research explains why our world looks
increasingly threatening despite consistent reductions in real-world threats.
"It
also shows that the more people share information, the further that information
gets from the facts and the more resilient it becomes to correction."
