Most of us greet news of a looming threat with skepticism. “Show me” is the usual reaction. We are like the mayor of the fictitious Amity Island in Jaws, who refuses to shut down the town’s beaches because officially acknowledging shark attacks would hurt tourism.
People who maintain that climate change demands a coordinated global response – now! – are in the same position as the police chief and the scientist in Steven Spielberg’s 1975 film. They implore the mayor to respond rationally to risk. If the evidence about a menace is properly explained, they believe, then the right policy will be forthcoming.
The mayor came around only after an unmistakable shark attack shamed him into acting. He gulped, “My kids were on that beach.” Sometimes reality mirrors the movies. When the role of chlorofluorocarbons in creating the ozone hole emerged in the late 1970s, the aluminum industry first squawked at proposed measures to eliminate the gases from their industrial processes. But they backed down, and the changes eventually mitigated the problem with little long-term disruption. Governments banned tetraethyl lead from gasoline once the cumulative neurotoxicity became clear, and levels of lead in human bloodstreams have been dropping since. These changes took years, but they did happen.
Action to deal with climate change might have followed this pattern: The scientific evidence reported in peer-reviewed journals has been mounting steadily. A large portion of climate scientists believe that the pace of climate change has surpassed the worst-case scenarios predicted just a few years ago. Prominent voices have been exhorting the public to set a price on carbon and other measures to reduce emissions. But the response to climate change has stalled.
Climate change denial plugs into a number of cognitive biases, the same ones that made the mayor in Jaws so determined to open the beaches in the face of warnings from a scientist. Everyone is prone to these blind spots, and resisting them requires vigilance. They include:
- The bandwagon effect: taking one’s cue from what everybody is doing, in this case, doubting the science
- Confirmation bias: accepting only data that confirms one’s prior beliefs
- Hyperbolic discounting: favoring immediate payoffs instead of larger long-term rewards
- Neglect of probability: the tendency to ignore probability when making a decision under uncertainty
- Zero-risk bias: a focus on reducing a small risk to zero rather than going for a larger reduction in larger risk
