Over the past several weeks I have explored our predictive ability. Last week, I ended with an observation that we tend to look away from the mistakes in our predictions. At first glance, this does not seem to be a successful survival strategy. A student doesn’t submit assignments for the first few weeks of class, then asks how they can make up the work and get a good grade. We must reconcile the reality of our circumstances with a constructed fantasy future. Shouldn’t we be learning from our mistakes? Why are we so good at self-deception?
Dreamweavers
We are the most creative of social animals. Deception is the creation of an illusion. If we want the world to be a certain way, why shouldn’t we construct a reality that conforms to our desires? We have little control over our instinctual responses to sense data. We pull back our hand from the hot burner on a stove, for example. But we must interpret most of our sense data, and that interpretation depends on our ability to filter out data which is non-essential to our needs. We apply our own unique weighting system to the events around us.
Because of that, eyewitness testimony has been shown to be fallible. We do not record events and place them into memory like the footage of a surveillance camera. We use our perception, our previous knowledge and beliefs as well as our expectations to construct a narrative. In her 1979 book Eyewitness Testimony, Elizabeth Loftus recounted several examples of the errors in our perception and memory. Erroneous eyewitness testimony accounts for two-thirds of all DNA exonerations, according to the Innocence Project.
Social Animals
Robert Trivers is an evolutionary biologist whose 2011 book The Folly of Fools: The Logic of Deceit and Self-Deception in Human Life argued that we practice self-deception to become more effective at deceiving others. Natural selection would favor individuals who are good at self-deception. I think Trivers might have it backwards. Self-deception is an incidental effect of our need to deceive others. Our survival in a social group depends on camouflage. We get so good at it that we sometimes delude ourselves.
In his 1982 book, Chimpanzee Politics, Frans de Waal examined the strategic social interactions between chimpanzees at the Arnhem Zoo in the Netherlands. Subgroups within a colony form alliances in support of a particular leader who uses aggressive displays to enforce dominance. Sexual relations promote social cohesion. Diplomacy helps reconciliation after fights break out. Chimps practice concealment to make it difficult for another member of the group to predict what is going to happen. Hiding signs of aggression before launching an attack is one example. Chimps hide food, or hide their excitement at finding a food source to protect it for themselves.
Conspiracy Theories
Human beings use concealment as well, but also practice intentional deception designed to create a false belief in others. Concealment is a cloaking action. Deception is a creative act, the construction of an illusion. Conspiracy theories involve both concealment and deception.
Alex Jones, the former owner of the web site Infowars, promoted a conspiracy theory that the shooting of twenty first graders at Sandy Hook Elementary School in Newton, Connecticut was a hoax, a government conspiracy designed to arouse public anger and enact more gun control legislation. Jones’ accusations prompted some listeners to harass the parents of the slain children.
The parents sued Jones for defamation. A jury found Jones guilty and awarded the parents over a billion dollars in damages. Jones declared bankruptcy and was forced to auction Infowars to pay the damages (Source and Source). Jones’ deception fostered a belief in his listeners that the parents and the government were concealing the real events of the school massacre.
Nothing to See Here
A chimpanzee learns to act noncommittal to avoid suspicion from a dominant member of the troop. In 2005, John Roberts was nominated first for associate justice then Chief Justice of the Supreme Court. At a Senate confirmation hearing he said, “[I]t’s my job to call balls and strikes, and not to pitch or bat” (Source). As a lawyer in the Reagan Administration, both Roberts and Samuel Alito had supported the unitary executive theory. This was a controversial reinterpretation of Article 2 of the Constitution that expanded the power of the president beyond the bounds of any Congressional checks (Source). Once confirmed, Roberts would no doubt pursue this and other conservative theories that aimed to overthrow established court precedents regarding abortion, gun control, campaign finance and the limits of free speech. To get confirmed, however, he skillfully concealed that agenda (Source).
In 1987 the Senate, led by Democrats, voted down the nomination of Robert Bork to the Supreme Court. Because the confirmation hearings were broadcast, the Senators were apt to strike performative poses much as they do now. Senator Ted Kennedy, brother of the assassinated John F. Kennedy, issued a vituperative public statement that predicted an undoing of all the liberal reforms of the past 50 years if Bork were confirmed. Decades of Bork’s past writing were introduced at the Judiciary Committee headed by Senator Joseph Biden (Source). Bork’s supporters felt that they had little opportunity for rebuttal in the public arena.
Since then nominees to the court undergo extensive preparation for the confirmation hearings (Source). They are taught to adopt a noncommittal attitude when answering questions from Senators. To avoid prejudicing future cases, they elect not to comment on any issues that might come before them. Within this institutionalized and ritualized confirmation process, concealment is a survival strategy.
Groupthink
Self-deception exists both at the individual and group level. In the 1970s and 1980s, Psychologist Irving Janis published several books on groupthink, a term he coined in 1971. In a group of individuals, loyalty and consensus take priority over a dispassionate evaluation of evidence (Source). A case familiar to many of us is the justification that the Bush administration used to initiate a war against Iraq. Based on hearsay and sketchy evidence, President Bush and a key group of advisors became convinced that Iraq’s leader, Saddam Hussein, had weapons of mass destruction. They ignored and concealed any evidence to the contrary as they presented their justification for war to the international community (Source).
President Trump surrounds himself only with those who agree and submit to his ideas, values and theories. Like a troop of chimpanzees, loyalty to the leader is paramount. In February 2026, Trump became convinced that a “shock and awe” strike on Iran’s leadership would cripple the Iranian military and perhaps usher in a more compliant regime (Haberman & Swan, 2026, p. 396) Vice-President Vance was one of the few in the cabinet to question the viability and success of such a plan. He is the only member of the cabinet that Trump cannot fire.
Conclusion
Last week I made the distinction between how we come in contact with the world around us through our senses and how we engage with the world through our errors. We want to avoid harsh judgment from ourselves and those around us. We deceive ourselves because we must live with ourselves. Next week I want to explore how we engage in self-deception as groups. I hope to see you next week.
