Loughborough University: Not calling out friends’ and family’s COVID-19 vaccine falsehoods on WhatsApp can further the spread of misinformation – here’s why we don’t correct them

In a first-of-a-kind public report, experts from Loughborough University’s Online Civic Culture Centre have uncovered the social norms that shape whether people challenge misinformation about COVID-19 vaccines in the largely hidden worlds of personal messaging platforms such as WhatsApp and Facebook Messenger.

Professor Andrew Chadwick, Professor Cristian Vaccari, and Dr Natalie-Anne Hall found personal messaging encourages what they call ‘hybrid public-interpersonal communication’, which has distinctive implications for how vaccine misinformation spreads.

“Discussion of vaccines mostly happens in small messaging groups among family, friends, and work colleagues – where people know each other well and tend to trust each other”, say the researchers.

“Paradoxically, this can increase the likelihood that misinformation goes unchallenged. This is because, on personal messaging, people have a norm of conflict avoidance.

“Importantly, for some people conflict avoidance is seen as easier to perform on personal messaging than it is during in-person communication.”

The report, based on nine months of intensive fieldwork funded by the Leverhulme Trust from a £347,000 grant, says seeing misinformation leads some people to “disengage from vaccine talk on personal messaging”.

“This presents a further paradox”, say the researchers, “they know the content of the misinformation posts but do not speak up, even if they disagree with it.

“These signals of tacit acceptance in a family, friend or school group can enhance the legitimacy of misinformation and contribute to its further spread.”

The report also looks at what people do when they encounter vaccine misinformation in larger personal messaging groups, such as among school parents or work colleagues.

The researchers found people fear that if they try to correct misinformation, they will be seen as undermining group cohesion by provoking conflict and they worry about their knowledge of the safety of COVID-19 vaccines. These risks are perceived to be greater the more ‘public’ the group is, even though school and work messaging groups are never fully public in the same way as social media.

Other key findings include:

‌Some people try to find routes around the norm of conflict avoidance, for example by sharing criticisms of vaccine misinformation in encounters they perceive to be less risky. Some people scale up and down between different groups, both large and small, or use one-to-one messaging to gauge others’ experiences and opinions.

But conflict avoidance casts a long shadow. Scaling and gauging may help build solidarity among those positive about vaccination, but these practices also evade opportunities to address misinformation in the contexts where it appears.

Also, challenging vaccine misinformation overtly can backfire and lead people to exit dialogue. Vaccination talk is then deemed off-limits, leaving personal messaging to continue but only on the basis of “safer,” less conflictual topics.
