The Stain on the Wall: How False Ideas Stick With Us - Deepstash

“Out, damned spot! out, I say!”

Lady Macbeth’s famous line concerns seeing the blood of a murdered man on her hands. She has washed her hands and tried to remove the stain. But the stain remains in her mind. And in her dreams and while sleepwalking, she still rubs her clean hands trying to remove the spot of blood from the man her husband and she murdered.

Stains are hard to remove. Even when the evidence is gone, we may still see and remember the remnants. Similarly, the gist of ideas sticks with us, even when the details are lost or discredited.

Spaghetti On The Wall

During a disinformation campaign, people will toss out a lot of ideas. Imagine those ideas as pieces of spaghetti thrown against the wall. Some ideas stick. Many bounce off and fall to the ground. Eventually, the spaghetti dries out and the crusty pieces fall as well. In this fashion, the details of the disinformation campaign are lost as the news moves to another topic.

Plain Spaghetti Vs Spaghetti With Sauce

Now add some spaghetti sauce. If the noodles are coated in a nice tomato sauce, that will splatter against the wall as well, and a tomato sauce stain is hard to remove. The stain will remain on the wall and the idea will remain in someone’s mind. The basic idea of the disinformation campaign will remain.

The Resulting Stain

Cognitive psychology studies how people remember the details of an experience and the gist of an idea. In a classic study, Bransford and Franks (1971) threw spaghetti against the wall and measured the resulting stain. Actually, what they did was give people short sentences and then asked them questions about each one.

Here are 4 examples of a longer set:

  • The girl lives next door. Who does?
  • The scared cat was running from the dog. What was?
  • The girl who lives next door broke the window. Broke what?
  • The dog was barking. What was?

The Gist Of An Idea

In creating the sentences that people studied, Bransford and Franks related each to an underlying understanding of different situations—the basic gist. Some sentences presented pieces of the underlying idea that “the girl who lives next door broke the large window on the porch”, while others of the idea that “the scared cat running from the barking dog jumped on the table.” Crucially, the full idea was never presented. Yet when people were given a memory test later, they often rejected some of the small pieces they did see and consistently accepted the basic underlying idea—the gist remained.

The Gist Of Disinformation, The Stain On The Wall

How could this apply in a disinformation campaign? How could the spaghetti tossed against the wall leave a stain? Let’s consider White Replacement Conspiracy Theory. This is a disinformation campaign that suggests that some unidentified group of elites is conspiring to change the voters in the US. The idea is that these elites are bringing in immigrants to replace the existing population so they can hold power.

The More The Spaghetti…

This set of ideas contains racism and anti-immigrant undertones. Many politicians and media personalities have made statements related to this idea. Someone can find reports about these statements in articles from The New York Times, the Washington Post, and NPR. The Times noted that this basic idea has been covered in some form on over 400 of Tucker Carlson’s shows on Fox News in the last few years.

That’s a lot of spaghetti being thrown against the wall.

… The Bigger The Stain

The gist remains. The stain on the wall is hard to remove. In the case of this conspiracy theory, the basic idea is widely accepted. In a recent survey, the Associated Press asked if people agreed with the idea that a group of elites was trying to replace native-born Americans with immigrants who agreed with their political views. Around one-third of respondents stated they agreed with the statement: 32% agreed with the underlying idea of a conspiracy theory.

The disinformation campaign has left a serious stain.

The Supply Of Truth Must Start Early, Be Big And Be Constant

To counter disinformation, the truth must be as aggressive. In a recent study, Broockman and Kalla (2022) paid people to switch from watching Fox News to CNN for a month. When people changed their news diet, their beliefs changed as well. Providing accurate information early may make it harder for disinformation to leave a stain. And changing to accurate information even after exposure to disinformation may help to clean the stain off the wall. But it takes time and a lot of truthful information. And when people went back to watching Fox, their ideas and beliefs returned to baseline.

The Risk of Disinformation

The risk of disinformation campaigns is not simply the individual statements. Those ideas are the spaghetti thrown against the wall. Disinformation campaigns present varied ideas that are often discredited, and people generally forget individual statements. But people will remember the gist of the idea.

The risk is that the underlying idea will remain. The damage of disinformation campaigns will outlast individual false statements.

Stains are hard to remove. Even when the evidence is gone, we may still see and remember the remnants. Similarly, the gist of ideas, true and false, sticks with us, even when the details are long lost or discredited.
