Survival of the Fibbest? Study Suggests BS Conspiracy Theories Have Roots in Human Evolution
According to researchers, the "Big Lies" of leaders like Trump may be deeply ingrained in human development.
Aug 09, 2021
A new paper by two political scientist and an anthropologist aims to explain how humans have evolved to spread conspiracy theories, misinformation, and other falsehoods through communities as a way of gaining an advantage over opposing factions--maintaining the upper hand in a society by mobilizing large groups of people and securing their loyalty, as former President Donald Trump and other demagogues throughout history.
Danish political scientists Michael Bang Petersen and Mathias Osmundsen worked with American anthropologist John Tooby to publish the paper, "The Evolutionary Psychology of Conflict and the Functions of Falsehood," which Petersen discussed in an in-depth interview with Salon published Sunday.
The researchers pointed to other animal species using falsehoods to gain the upper hand in conflicts--such as animals that "spread false information" by making themselves appear larger to scare an opponent--but noted that in communities of humans, the spread of falsehoods is mainly beneficial in a group of people.
"Belief in information and content that other people would say is blatantly false is becoming more widespread. It can have some pretty dire consequences, as we could see for example with the storming of the Capitol on January 6."
--Michael Bang Petersen
The study identified three functions of sharing information--"group mobilization, coordination of attention, and signaling commitment."
In evolutionary terms, the researchers argue in the paper, "accomplishing these goals efficiently is what gets selected... not truth or veracity."
"When you want to mobilize your group, what you need to do is find out that we are facing a problem, and your way of describing that problem needs to be as attention-grabbing as possible before you can get the group to focus on the same thing. In that context, reality is seldom as juicy as fiction," said Petersen. "By enhancing the threat--for example, by saying things that are not necessarily true--then you are in a better situation to mobilize and coordinate the attention of your own group."
Petersen and Paul Rosenberg, who interviewed him for Salon, both noted that the research immediately brought Trump to mind--whose repeated statements about "fake news" and attacks on the news media, a "migrant caravan" traveling toward the southern U.S. border in 2018, and election officials who "stole" the 2020 election for President Joe Biden could be seen as mobilizing and coordinating his supporters around "attention-grabbing" problems.
Trump used falsehoods to establish conflicts between his base and the Democratic Party, political opponents, and other groups numerous times, Petersen said, including his claim "that there were more people at Trump's inauguration than Obama's inauguration, and everyone could clearly see that was false."
"Either Trump is ignorant--and I don't believe he's ignorant, I think he is an extremely skilled or intuitive psychologist who knows how to mobilize his followers--or it suggests he's thinking, 'I can say whatever I want, and I care so little about the other group's opinions that I can say things that are blatantly false, where they know that I know it's false, and it's precisely because they know that I know that it's false that it serves as a dominance signal,'" said Petersen.
Petersen's theory of the deliberate use of falsehoods and conspiracy theories also offers an explanation for how hundreds of Trump's supporters proceeded to the U.S. Capitol on January 6 to take part in a violent attempted insurrection.
"It seems that those kind of belief systems--belief in information and content that other people would say is blatantly false--is becoming more widespread," Petersen said. "It can have some pretty dire consequences, as we could see for example with the storming of the Capitol on January 6."
While it is demonstrably true that Trump lost the 2020 election, polls conducted as recently as May of this year showed that that 53% of Republican voters still view Trump as the rightful winner of the 2020 election.
Trump and leaders like him--and humans as a whole--have evolved to spread information not because it is necessarily true, but because it allows them "to accomplish certain socially important phenomena, such as mobilizing our group or signaling that we're loyal members of the group," said Petersen.
An Urgent Message From Our Co-Founder
Dear Common Dreams reader, It’s been nearly 30 years since I co-founded Common Dreams with my late wife, Lina Newhouser. We had the radical notion that journalism should serve the public good, not corporate profits. It was clear to us from the outset what it would take to build such a project. No paid advertisements. No corporate sponsors. No millionaire publisher telling us what to think or do. Many people said we wouldn't last a year, but we proved those doubters wrong. Together with a tremendous team of journalists and dedicated staff, we built an independent media outlet free from the constraints of profits and corporate control. Our mission has always been simple: To inform. To inspire. To ignite change for the common good. Building Common Dreams was not easy. Our survival was never guaranteed. When you take on the most powerful forces—Wall Street greed, fossil fuel industry destruction, Big Tech lobbyists, and uber-rich oligarchs who have spent billions upon billions rigging the economy and democracy in their favor—the only bulwark you have is supporters who believe in your work. But here’s the urgent message from me today. It's never been this bad out there. And it's never been this hard to keep us going. At the very moment Common Dreams is most needed, the threats we face are intensifying. We need your support now more than ever. We don't accept corporate advertising and never will. We don't have a paywall because we don't think people should be blocked from critical news based on their ability to pay. Everything we do is funded by the donations of readers like you. When everyone does the little they can afford, we are strong. But if that support retreats or dries up, so do we. Will you donate now to make sure Common Dreams not only survives but thrives? —Craig Brown, Co-founder |
