„Jetzt steht es komplett anders drin“
“… People often are unaware of their own ignorance (Kruger & Dunning, 1999), seek out information that supports their current preferences (Nickerson, 1998), process new information in biased ways that strengthen their current preferences (Lord, Ross, & Lepper, 1979), affiliate with other people who have similar preferences (Lazarsfeld & Merton, 1954), and assume that other people’s views are as extreme as their own (Van Boven, Judd, & Sherman, 2012). In sum, several psychological factors increase extremism, and attitude polarization is therefore hard to avoid.”

Political extremism is supported by an illusion of understanding.
