Conspiracy theories in general are not necessary bad, according to psychologists who study them. “If we were all completely trusting, it would not be good for survival,” explains Rob Brotherton, an academic psychologist and author of Suspicious Minds: Why We Believe Conspiracy Theories. “Sometimes people really don’t have our best interests in mind.”
