"Naïve realism" is defined as the feeling that we see things objectively, as they really are, that our worldview enjoys a particular authenticity, and therefore everybody else should agree with us ... if they don't, either they lack relevant information or they see things through the distorting, blinding prism of their (religious, political, ideological) bias.
We would perhaps concede that some of our views have been shaped by our personal experience, but we feel that in our own particular case such factors have led to increased insight, whereas in others' case they have impaired their perception, inference and judgment abilities.
Cultural psychologist Jonathan Haidt points to naïve realism as "the major obstacle to world peace and social harmony" (The Happiness Hypothesis: Finding Modern Truth in Ancient Wisdom), because it works not only at the individual but also at the group level, contributing to splitting the world in good and bad (people, ideas).
Such an attitude is typical of fundamentalist political and religious groups like the JWs. But it's worth remembering that's a common inclination to be recognized and fought against: all of us are bound to judge asymmetrically when it comes to detecting (our own or others) bias.
