Consider a 2018 study conducted with more than 1,000 residents living in South Florida intended to assess how they might perceive the vulnerability of their property and their communities to severe storms. Researchers asked about their political affiliation and their support for policies such as zoning laws, gasoline taxes and other measures to address climate change.
Half of the participants received a map of their own city that illustrated what could happen just 15 years from now at the present rate of sea level rise if there were a Category 3 hurricane accompanied by storm surge flooding. Those who had viewed the maps were far less likely to believe climate change was taking place than those who had not seen the maps.
Furthermore, those who saw the maps were less likely to believe that climate change increases the severity of storms or that sea level is rising and related to climate change. Even more dramatically, exposure to the scientific map did not influence beliefs that their own homes were susceptible to flooding or that sea level rise would reduce local property values.
Consistent with national surveys, party identification was the strongest predictor of general perceptions of climate change and sea-level rise. Of the group that were shown the maps, those who classified themselves as Republicans had the strongest negative responses to the maps. Researchers theorize that was because they had the strongest identity ties to their “tribe” than the other groups.
The Egocentric Bias
Egocentric bias is the tendency to rely too heavily on one’s own perspective and have a higher opinion of oneself and one’s status than is reality. This self-centered perspective gives rise to many others, including overestimating how successfully we communicate with others, dismissing different points of view as wrong, and overestimating how much others share our attitudes and preferences.
In the fall of 2008, the Rand Corporation’s American Life Panel asked respondents how likely they were to vote for Barack Obama, John McCain, or a third candidate in the upcoming presidential election. Then, they were asked how likely each candidate was to win the election. The more strongly people favored a certain candidate, the higher they estimated that candidate’s likelihood of winning the election. For instance, those who strongly preferred Barack Obama predicted that he had a 65% chance of becoming the president, while those who preferred another candidate estimated Obama only had a 40% chance of victory.
The results held true for both candidates and were replicated in the 2010 state elections.
These patterns persisted no matter how the results were stratified: respondents of every age, race, and education level thought that their preferred candidate was more likely to win the election. When people changed their candidate preferences over time, their expectations about the outcome of the election shifted as well.
Although at a theoretical level we are aware that other people can have different perspectives to our own, egocentric bias often results in imposing our own perspectives to others even when it is unwarranted. In addition, this bias can influence ethical judgements to the point where people not only believe their views are better than others but also the morally sound perspective thereby judging anyone who disagrees as immoral.
Research shows it takes approximately 250 milliseconds to decide whether something is right or wrong, and we make instantaneous moral evaluations even when we cannot explain them. Moral judgements – like any other judgements – are highly prone to egocentric bias.
A 2020 study investigated whether people perceive actions as morally right when they serve the interests of their group but as morally wrong when they serve outgroup interests. Researchers found that egocentric bias regarding moral judgements about ingroup members would be especially strong among participants who are defensive about their group identity (collective narcissism). In one of the experiments, they asked English and Polish participants to judge the morality of decisions made by ingroup and outgroup members and found that group identity influenced participants’ moral judgements but only those high in collective narcissism. In a different experiment, they asked American participants (Democrats and Republicans) to evaluate the morality of the collective US Senate decision to nominate Brett Kavanaugh to the Supreme Court. Republican voters found the decision of the US Senate overwhelmingly upstanding and moral while Democrats condemned it.
Unless we intentionally examine a situation from a completely different viewpoint, the egocentric bias is often the culprit of the sort of righteous indignation that brings civil conversations to a screeching halt. When the egocentric bias is in high gear, one sees his or her perspective as the only correct perspective. Furthermore, those who disagree with that perspective or offer an alternative perspective are not only wrong, but also immoral.
Mark Twain may have said it best:
It ain’t what you don’t know that gets you into trouble. It’s what you know for sure that just ain’t so.
Overcoming these biases and evolving into a more intelligent and enlightened understanding of the world is the cornerstone of intellectual humility – the recognition that the things you believe might be wrong. And this requires intention and actual changes in the physiology of the brain to accept information that challenges a deeply held belief.
Neuroscientist, Kevin Dunbar gave students research that either backed up or disproved what they believed to be true about antidepressants. As students reviewed the data, Dunbar was watching their brain activity in an fMRI machine. Data that aligned with their opinions activated the part of the brain associated with learning. When the students reviewed data that was incongruent with their opinions, the learning region didn’t come alive. Instead, the areas associated with effortful thinking and thought suppression were engaged. Dunbar concluded that when people are presented with facts that contradict misconceptions or address knowledge gaps, instinctively, the learning brain shuts down. When we aren’t open to being corrected, the brain is simply unable to learn.
The bottom line: the next time you are convinced of your “rightness,” it might be worth it to take a minute to examine your biases.
Outstanding piece Melissa. Do you think social media has deepened biases? Many people now only read, listen to or watch what matches their own beliefs (Fox, CNBC). I see very little dialogue and more talking over and talking louder. This increases isolation and make constructive conversation very difficult.
