One of the great mysteries of history is how an entire nation of people can follow a leader into tragedy — a stupid war, economic morass, cultural suicide, genocide, or other tragedy — without appearing to notice they were going against their national values, against reason, against morality.
I wonder if part of the answer can be found by studying the way our brains perceive things, in particular, the way our brains force us to see things that are not so.
Some things are just so unbelievable, our brains tell us we’re seeing something different, something more believable. Here are two examples, the Charlie Chaplin mask illusion, and the Einstein mask illusion.
Chaplin — you know it’s concave, but the nose sticks out every time:
Einstein — is Big Brother really watching you? What do your eyes say?
Here’s a nasty little kicker: Even when most people know that it’s an illusion, they can’t perceive the illusion-in-action; as Paul Simon wrote, “Still a man sees what he wants to see and he disregards the rest.” See Stephen Fry’s discussion about the illusion from BBC2:
Historical applications
- CIA chief William Colby was involved in Operation Phoenix during the Vietnam War. When investigations revealed that the operation involved torture, many people refused to believe the U.S. would be involved in torture (good!). And even after he admitted to Congressional committees that he had personally authorized the torture, people had difficulty believing it. David Wise wrote an article about Operation Phoenix for the New York Times Magazine, July 1, 1973: “Not one of Colby’s friends or neighbors, or even his critics on the Hill, would, in their wildest imagination, conceive of Bill Colby attaching electric wires to a man’s genitals and personally turning the crank. “Not Bill Colby… He’s a Princeton man.'”
- “[T]he Russians are finished. They have nothing left to throw against us,” a confident Adolf Hitler told Gen. Franz Halder in July 1941. Russia mired down the German army, making the phrase “the Eastern Front” a dreaded death sentence in German commands. In the end, it was the Soviet Army that first got to Berlin, and captured Hitler’s command bunker where der Führer had committed suicide a short time before. Adding to the historic irony, twice over: First, Stalin refused to believe his intelligence service reports that the Nazis were massing on the border of Russia, just two years after the Molotov-Ribbentrop Pact, which pledged neither nation would invade the other. Second, Hitler’s generals had studied Napoleon’s invasion of Russia in 1812, working to avoid all the mistakes Napoleon made. So sure were the Nazis of their superiority to Napoleon in every way, they invaded Russia on the anniversary of Napoleon’s invasion, June 22, 1941. Great shades of Santayana’s Ghost!
- Bush administration historians will wonder why Bush was able to do what he did, in the Iraq war and other situations foreign and domestic, with even members of his own party who saw him close up believing he’d do something different. See this story by Ron Susskind, “Faith, Certainty and the Presidency of George Bush,” New York Times Magazine, October 17, 2004.
- The Gulf of Tonkin Resolution, based on an incident in the Gulf of Tonkin near Vietnam. (See also documents from the National Security Agency archives.)
- Weapons of Mass Destruction in Iraq.
Richard Feynman discussed at length how scientists know their experimental results are accurate, and how to keep science honest. He pointed out that most of the time, errors creep in at the start, and some people just refuse to believe they exist. It is easiest to fool ourselves, Feynman said — and so a good scientist understands that, and protects against self-deception. If only other disciplines could adopt that philosophy, strategy and tactics!
Faith can get us through troubled times, but often gets us into troubled times in the first place.
Do you have other examples of self-delusion by illusionary means?
