According to Yale’s Cultural Cognition Project, for example, one’s “cultural worldview”—that would be political leanings or ideological outlook to the rest of us—explains “individuals’ beliefs about global warming more powerfully than any other individual characteristic.”16 More powerfully, that is, than age, ethnicity, education, or party affiliation. The Yale researchers explain that people with strong “egalitarian” and “communitarian” worldviews (marked by an inclination toward collective action and social justice, concern about inequality, and suspicion of corporate power) overwhelmingly accept the scientific consensus on climate change. Conversely, those with strong “hierarchical” and “individualistic” worldviews (marked by opposition to government assistance for the poor and minorities, strong support for industry, and a belief that we all pretty much get what we deserve) overwhelmingly reject the scientific consensus.17 The evidence is striking. Among the segment of the U.S. population that displays the strongest “hierarchical” views, only 11 percent rate climate change as a “high risk,” compared with 69 percent of the segment displaying the strongest “egalitarian” views.18 Yale law professor Dan Kahan, the lead author on this study, attributes the tight correlation between “worldview” and acceptance of climate science to “cultural cognition,” the process by which all of us—regardless of political leanings—filter new information in ways that will protect our “preferred vision of the good society.” If new information seems to confirm that vision, we welcome it and integrate it easily. If it poses a threat to our belief system, then our brain immediately gets to work producing intellectual antibodies designed to repel the unwelcome invasion.19 As Kahan explained in Nature, “People find it disconcerting to believe that behavior that they find noble is nevertheless detrimental to society, and behavior that they find base is beneficial to it. Because accepting such a claim could drive a wedge between them and their peers, they have a strong emotional predisposition to reject it.” In other words, it is always easier to deny reality than to allow our worldview to be shattered, a fact that was as true of die-hard Stalinists at the height of the purges as it is of libertarian climate change deniers today. Furthermore, leftists are equally capable of denying inconvenient scientific evidence. If conservatives are inherent system justifiers, and therefore bridle before facts that call the dominant economic system into question, then most leftists are inherent system questioners, and therefore prone to skepticism about facts that come from corporations and government. This can lapse into the kind of fact resistance we see among those who are convinced that multinational drug companies have covered up the link between childhood vaccines and autism. No matter what evidence is marshaled to disprove their theories, it doesn’t matter to these crusaders—it’s just the system covering up for itself.20 This kind of defensive reasoning helps explain the rise of emotional intensity that surrounds the climate issue today.
