2017-29: Online Information & Fake News
In 2017 the proportion of adults in the UK consuming news online exceeded those who watched TV news (74% versus 69%). This was one of many interesting facts contained in a POSTnote[No 559], ‘Online Information & Fake News’, published in July by the Parliamentary Office of Science & Technology.
The POSTnote considers inter alia how people access news online, how algorithms and social networks influence the content that users see, and options for mitigating any negative impact. In particular, it explores:
- how people in the UK access and share news online
- the effects of filtering
- the factors driving fake news and its effects
- approaches to addressing the challenges
One interesting idea briefly mentioned in the POSTnote is that put forward by Sander Van der Linden, Director of the Cambridge Social Decision-Making Lab , who argues that it may be possible to ‘inoculate’ against misinformation by pre-emptively warning people about politically motivated attempts to spread misinformation.
Van der Linden explained the idea in a Sunday Lecture he
gave in Conway Hall in May, entitled ‘ Beating the Hell Out of Fake News
’. He
says he started thinking about the vaccine metaphor when he “came across some
interesting work that showed how models from epidemiology could be adapted to
model the viral spread of misinformation, i.e. how one false idea can rapidly
spread from one mind to another within a network of interconnected individuals.
This led to the idea that it may be possible to develop a ‘mental’ vaccine.”
His team tested the idea in a study that focused on disinformation about climate change. There was “a debunked petition that formed the basis of a viral fake news story that claimed that thousands of scientists had concluded that climate change is a hoax.” The challenge was to see if it would be possible to “inoculate the public against this bogus petition”, and to some extent, he succeeded. “Vaccines do not always offer full protection,” he notes, “but the gist of inoculation is that we need to play offence rather than defence and that it’s better to prevent than cure. It is one tool, among many, to help each other navigate this brave new world.”
