Critical reading is civic self-defense, and we keep treating it like an elective.
We talk about political polarization like it’s some kind of weird fog that drifted in one day and just never left. But polarization doesn’t work that way. It gets built. It gets fed. And it gets optimized.
One of the most underrated inputs into that machine is a literacy gap. Not “can you read words” literacy. Critical reading, media literacy, civic literacy. The skills that help you tell the difference between an argument and a performance. Between evidence and a vibe.
A lot of those skills get trained in the humanities. When we defund humanities education, we don’t just cut a few “extra” classes. We quietly erode the very muscles people use to resist manipulation.
The Literacy Gap Nobody Wants to Budget For
Here’s what the literacy gap actually looks like: 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 spent years documenting how often students struggle to evaluate the credibility of online information in everyday situations. The stuff that shows up in your feed every single day.
When shared reality gets shaky, polarization doesn’t need to “win.” It just needs to spread.
When large numbers of people can’t reliably evaluate the claims they’re seeing, shared reality fractures. And once shared reality fractures, polarization doesn’t have to fight for ground. It just fills the space.
Humanities Classes Teach the Skills Propaganda Hates
Propaganda thrives on passive reading. Passive reading is what happens when you accept the framing you’re handed and react emotionally before you’ve even thought to ask a single basic question.
Humanities training teaches the pause that propaganda hates: who benefits if I believe this? What’s missing from the frame? What emotion is this trying to trigger, and why right now? Is this evidence, or just a story that feels good to repeat?
The key thing is that these skills are teachable. A large study published in the Proceedings of the National Academy of Sciences found that a digital media literacy intervention meaningfully improved people’s ability to distinguish false news from mainstream news, both in the U.S. and India.
So when humanities get treated as optional extras, we’re not just trimming the artsy stuff. We’re cutting a layer of democratic self-defense.
This Is Not a STEM vs. Humanities Argument
STEM matters. A lot. This is a systems argument, not a culture-war rant.
A society can be technically brilliant and still be remarkably easy to manipulate if people haven’t been 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 Actually Fuel Polarization
- Shared reality gets weaker. When people can’t verify what’s true, public debate doesn’t just fracture into different opinions. It fractures into different worlds, each with its own set of “facts.” Stanford’s civic online reasoning work makes clear that the evaluation gap is widespread and real.
- Outrage content wins more often. Polarization goes deeper than disagreement. It becomes identity warfare. Social media ecosystems reward content that sharpens the “us versus them” frame, and recently published research has found that out-group animosity is strongly correlated with engagement.
- The feed rewards heat over truth. A report from Columbia University’s Knight First Amendment Institute examined Twitter’s engagement-based ranking and found it amplified emotionally charged, out-group hostile content. Users reported feeling worse about people on the other side of the political aisle.
And the causal story matters too.
A 2025 paper in Science went even further, running a field experiment on X/Twitter that showed reranking exposure to partisan animosity content measurably shifted how much users disliked the opposing political group. In other words, the feed can actively nudge how much we hate each other.
Put all of that together and you get a nasty combination: less training in critical reading, more algorithmic amplification of divisive content, and more polarization as the predictable result.
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 your terms, track your evidence, and notice when your own logic falls apart.
A study in CBE — Life Sciences Education found that writing-focused instruction was associated with stronger critical thinking performance compared to traditional instruction in the same 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 when the information environment is engineered specifically to short-circuit it.
What We Can Actually 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 as democracy maintenance, not decoration.
- Teach media literacy early and consistently. Verification, sourcing, and framing analysis should be standard curriculum, not elective topics.
- Bring back writing across the curriculum. Writing builds reasoning. That’s not an opinion, it’s well-documented.
- Support public spaces that reward nuance. Libraries, local journalism, classrooms that value evidence over performance.
- Stop confusing volume with truth. That’s cultural work, and it starts with modeling it ourselves.
The Takeaway
When we defund the humanities, we don’t just cut electives. We cut the training in critical reading, rhetoric, writing, and source evaluation that democratic participation actually requires. When those skills erode, misinformation spreads faster, manipulation gets easier, and persuasion gets replaced by tribal reflex.
Democracy doesn’t only erode through force.
Sometimes, it erodes through misreading.
