According to a March 2020 study published in Frontiers in Psychology, people who regularly use Fox News, Twitter and Facebook tend to ”endorse more misinformation” and have less knowledge about COVID-19 treatment and symptoms than those who don't often engage with these sources. These users also tend to have more prejudicial attitudes toward Asian-Americans. The study surveyed 1,141 adults in March 2020.
Another March study published by a Harvard affiliate found that use of conservative media (Fox News, Rush Limbaugh) correlated with “beliefs in the malign underlying motives of some at the Centers for Disease Control and in the Chinese origin of the virus.” Exposure to Facebook, Twitter and YouTube correlated with beliefs that the CDC was exaggerating the threat to harm President Trump politically, that the virus was created by the U.S. government and that Vitamin C prevented infection.
