Critical reading is civic self-defense, and we keep treating it like an elective.
We tend to talk about political polarization like it’s some sort of weird fog that rolled in one day and never left. But polarization doesn’t just happen overnight. It gets built, it gets fed, and it gets optimized.
One underrated input in this polarization machine is a literacy gap. Not “can you read words” literacy, but critical reading, media literacy, and civic literacy. The skills that help you tell the difference between an argument and a performance, or between evidence and a “vibe.”
And yes, a lot of those skills are trained in the humanities. When we de-fund humanities education, we don’t just trim “extra” classes. We quietly weaken the muscles that help people resist manipulation.
The literacy gap nobody wants to budget for
Here’s what the literacy gap looks like in the wild: a headline becomes the whole story, a screenshot becomes “proof,” and a confident tone becomes credibility. That’s not a personal failure. It’s a skill issue, and skill issues scale fast.
Stanford’s History Education Group has repeatedly shown that many students struggle to evaluate the credibility of online information in common scenarios. In other words, the exact stuff that shows up in your feed every day.
When shared reality gets shaky, polarization doesn’t need to “win.” It just needs to spread.
When a lot of people can’t reliably evaluate claims, shared reality gets shaky. When shared reality gets shaky, polarization gets stronger.
Humanities classes teach the skills propaganda hates
Propaganda thrives on passive reading. Passive reading is when you accept the framing you’re handed, then react emotionally before you’ve even asked basic questions.
Humanities training teaches the pause propaganda hates: who benefits if I believe this? What’s missing from the framing? What emotion is this trying to trigger? Is this evidence, or just a story that feels good to believe?
The key point is that these skills are teachable. A large study in Proceedings of the National Academy of Sciences (PNAS) found that a digital media literacy intervention improved people’s ability to distinguish false news from mainstream news (in the U.S. and India).
So, when humanities get treated like optional extras, we’re not just cutting “artsy stuff.” We’re cutting a layer of democratic self-defense.
This is not “STEM vs. Humanities”
STEM matters. A lot. This is not a culture-war rant about science, coding, or practical skills.
Instead, it’s a systems argument. A society can be technically brilliant and still be easy to manipulate if people aren’t trained to evaluate language, framing, and sources. STEM helps us build powerful tools. The humanities help us notice when those tools are being used to distort reality, flatten nuance, and inflame conflict.
You need both hands on the wheel.
How humanities cuts fuel polarization
- Shared reality gets weaker.
When people struggle to verify information, public debate fractures. Not into “different opinions,” but into different worlds, each with its own set of “facts.” Stanford’s civic online reasoning work is a strong signal that the evaluation gap is widespread and consequential. - Outrage content wins more often.
Polarization isn’t only disagreement. It’s identity warfare. And social media ecosystems tend to reward the kind of content that sharpens “us versus them.” Research published in PNAS found that out-group animosity is strongly associated with engagement on social media. - The feed often rewards heat, not truth.
Columbia University’s Knight First Amendment Institute report on Twitter’s engagement-based ranking found it amplified emotionally charged and out-group hostile content compared with a reverse-chronological baseline, and noted that users reported feeling worse about their political out-group.
And the causal story matters too. A Science paper (2025) reported results from a field experiment on X/Twitter showing that reranking exposure to partisan animosity content shifted measured out-party animosity, which is basically a fancy way of saying the feed can nudge how much we dislike each other.
Put these together and you get a nasty combo: less training in critical reading plus more amplification of divisive content equals more polarization.
Writing is thinking, and we’re cutting thinking reps
One of the most underrated humanities skills is also one of the most powerful: writing. Writing forces structure. It forces you to define terms, track evidence, and notice when your own logic collapses.
A study in CBE — Life Sciences Education found that writing-focused instruction was associated with improved critical thinking performance compared with traditional instruction in that course context.
So, when schools cut writing-intensive courses, it’s not just a curriculum change. It’s fewer reps of disciplined thinking, at the exact moment our information environment is engineered to short-circuit it.
What we can do about it
This isn’t about shaming people for not reading enough books. It’s about rebuilding infrastructure.
- Fund humanities education like civic infrastructure. Treat critical reading and writing like democracy maintenance, not decoration.
- Teach media literacy early and often. Verification, sourcing, and framing should be standard, not optional.
- Bring back writing across the curriculum. Writing builds reasoning. Period.
- Support public spaces that reward nuance. Libraries, local journalism, community discussion spaces, classrooms that teach evidence over performance.
- Stop confusing volume with truth. This is cultural work too.
The takeaway
When we de-fund the humanities, we don’t just cut electives. We cut training in critical reading, rhetoric, writing, and source evaluation. When those skills decline, polarization gets stronger, misinformation spreads faster, and persuasion gets replaced by tribal reflex.
Democracy doesn’t only erode through force.
Sometimes, it erodes through misreading.
