If You Believe It, It’s Truer

People reflexively accept information as accurate if it aligns with their worldview, according to Ben-Gurion University researchers.

In a series of experiments, the researchers asked participants to respond to various opinion statements, such as “The internet has made people more isolated” or “The internet has made people more sociable,” and indicate as quickly as possible if the grammar of the sentence was correct or not. Later, they were asked if they agreed with each statement. Participants identified statements to be grammatically correct more quickly when they agreed with them, which revealed a rapid, involuntary effect of agreement on cognitive processing.

According to Dr. Gilead, “In order to make informed decisions, people need to be able to consider the merits and weaknesses of different opinions and adapt to new information. This involuntary, ‘reflex-like’ tendency to consider things we already believe in as being true, might dampen our ability to think things through in a rational way. Future studies could explore how other factors, such as acute stress or liberal or conservative viewpoints, affect this tendency to accept or reject opinions in a ‘knee-jerk’ manner.”
