What Types of News are People Motivated to Trust?
This graph measures motivated reasoning by topic. Bayesians' assessments P(True) would not be affected by "Pro-Positivity," "Pro-Party," or "Pro-Performance" news. News in the Pro-Positivity direction are: low infant mortality rates, other people are happy, high cancer survival rates, low global poverty rates, and few deaths in armed conflicts.
This graph shows that there is no evidence for positivity-motivated reasoning, and that moderate effect sizes as seen with politically-motivated reasoning and performance-motivated reasoning can be ruled out.
