False information online has left one in five girls feeling physically unsafe, according to The Truth Gap, a new report by Plan International. One in three say false information is affecting their mental health, leaving them feeling stressed, worried and anxious. Others reported concerns about bogus events advertised on social media placing them at physical risk, or unreliable medical advice that could harm their health.Girls and young women from low and middle-income countries were more likely to be affected by unreliable or false information online, and twice as likely to have questioned whether to get the vaccine than those in high income countries.The researchers are calling on governments to educate children and young people in digital literacy.Related to this, BBC Misinformation reporter Marianna Spring, who has also been subjected to misogynistic online, abuse set out to understand how why such content seems to be promoted on some social media platforms. We examine her findings.There is more from Marianna’s investigation in Panorama ‘ Online abuse :why do you hate me?’ And Emily Bird reports on robots used to study glaciers in situations which would be far too dangerous for human researchers.
