Coronavirus: False claims viewed by millions on YouTube
More than a quarter of the most-viewed coronavirus videos on YouTube contain “misleading or inaccurate information”, a study suggests.
In total, the misleading videos had been viewed more than 62 million times.
Among the false claims was the idea that pharmaceutical companies already have a coronavirus vaccine but are refusing to sell it.
YouTube said it was committed to reducing the spread of harmful misinformation.
The researchers suggested “good quality, accurate information” had been uploaded to YouTube by government bodies and health experts.
But it said the videos were often difficult to understand and lacked the popular appeal of YouTube stars and vloggers.
The study, published online by BMJ Global Health, looked at the most widely viewed coronavirus-related videos in English, as of 21 March.
After excluding duplicate videos, videos longer than an hour and videos that did not include relevant audio or visual material, they were left with 69 to analyse.
The videos were scored on whether they presented exclusively factual information about viral spread, coronavirus symptoms, prevention and potential treatments.
Videos from government agencies scored significantly better than other sources, but were less widely viewed.
Of the 19 videos found to include misinformation:
- about a third came from entertainment news sources
- national news outlets accounted for about a quarter
- internet news sources also account for about a quarter
- 13% had been uploaded by independent video-makers
The report recommends that governments and health authorities should collaborate with entertainment news sources and social media influencers to make appealing, factual content that is more widely viewed.
YouTube said in a statement: “We are always interested to see research and exploring ways to partner with researchers even more closely. However it’s hard to draw broad conclusions from research that uses very small sample sizes and the study itself recognises the limitations of the sample.
“We’re committed to providing timely and helpful information at this critical time. To date we’ve removed thousands and thousands of videos for violating our COVID-19 policies and directed tens of billions of impressions to global and local health organisations from our home page and information panels.
“We’re committed to providing timely and helpful information at this critical time, including raising authoritative content, reducing the spread of harmful misinformation and showing information panels, using NHS and World Health Organization (WHO) data, to help combat misinformation.”
