Episode Details

Roger Ailes grew up in Warren, Ohio. His father worked the line at a Packard plant, wiring cars for GM, taking orders from managers he resented. Men with college degrees who told him what to do and how to do it. Roger watched his father come home angry every night. He understood something visceral about that anger. He understood what it feels like to be talked down to by people who think they’re smarter than you.

He never forgot it.

Decades later, Ailes would take that wound, that resentment of educated elites and turn it into the most profitable media machine in American history.

Fox News didn’t happen by accident. It was engineered.

And what it was engineered to do is the most important story in American media. Not because of the politics. Because of what it does to the human brain.

It’s propaganda.

The Study That Changed Everything

In 2012, political scientist Dan Cassino at Fairleigh Dickinson University set out to measure what watching different news sources actually does to your knowledge of current events.

Not what people believe. Not what they feel. What they actually know.

His team surveyed 1,185 Americans. They asked them basic questions about domestic and international events. Which party controls the House. What economic sanctions against Iran are supposed to accomplish. Whether opposition groups in Egypt had successfully removed Mubarak. Real questions with verifiable answers.

Then they sorted respondents by news source.

The results were published and immediately went viral for good reason.

NPR listeners performed best. Sunday morning political show viewers came in second. Daily Show viewers ranked third.

People who watched no news at all answered about 1.28 international questions correctly out of 4.

Fox News viewers answered 1.08.

Dead last.

People who turned the TV off entirely and relied on nothing were more informed than people who tuned in to the most-watched cable news network in America.

Let that land for a second.

Watching Fox News is worse than watching nothing. Not differently informative. Not biased in a different direction. Actively, measurably worse than silence.

Cassino’s conclusion was direct: “The most popular of the national media sources, Fox, CNN, MSNBC, seem to be the least informative. But the largest effect is that of Fox News.”

Fox wasn’t tied for last. It was in a category of its own. A category below nothing.

This Wasn’t A Fluke

When the results went viral, Fox attacked the university. Conservatives called it partisan. The usual playbook.

So Fairleigh Dickinson ran the study again.

Same results.

Then other research institutions started looking. A study published in Frontiers in Psychology found that people who trusted Fox News for their information during the COVID-19 pandemic were more likely to believe demonstrably false claims about how the virus spreads. They were also more likely to hold prejudiced views toward Asian Americans. People who relied on NPR and the New York Times showed significantly higher accuracy on both counts.

A 2023 peer-reviewed study in a social psychology journal found that Fox News exposure specifically, after controlling for political ideology, education, and demographics, predicted higher levels of general conspiracy thinking over time. The effect wasn’t neutral and it wasn’t small. It built over time.

This is now one of the most replicated findings in American media research. Fox News viewers consistently know less than viewers of other news sources, and less than people who watch no news at all.

The question isn’t whether this is true. It’s been established. The question is why.

There’s a well-established concept in communications research called the Knowledge Gap Hypothesis, first described by Tichenor, Donohue
