Years ago, in a village in central Karnataka, I sat with a group of women who had just listened to a health official explain the importance of iron tablets during pregnancy. He had a PowerPoint. He spoke in English, then translated awkwardly into Kannada. He tossed around terms like ‘maternal mortality rate’ and ‘haemoglobin synthesis’. The women nodded politely. After he left, one turned to me and said, “He wants us to eat something, but we are not sick. Why would we take medicine when we are not sick?”

That moment has stayed with me. Not because the women were wrong—they weren’t. The communication was. It was a textbook case of what I’ve come to call the ‘altitude error’: the quiet assumption that knowledge needs only to be poured from a height into waiting, empty vessels. The official had data. He had good intentions. What he didn’t have was any real feel for the ground beneath his feet.

The Architecture of Talking Down

Science communication in India, and honestly in much of the world, carries an unspoken pecking order. The scientist, the doctor, the researcher—they are the knowers. The public, the patient, the farmer—they are the learners. This isn’t always malicious. It often grows out of training that prizes precision over connection, evidence over experience. But the damage is real. It erodes trust. It widens the gap between what science knows and what communities actually do.

When we talk down, a few things happen all at once. We reach for language that shuts people out. We assume that a lack of formal schooling means a lack of intelligence. We forget that people live inside thick webs of belief, money, and history, and any new fact has to find its place in that web. An iron tablet is never just an iron tablet. It’s a symbol of the formal healthcare system, which may or may not have treated you kindly. It’s an object entering a body already shaped by food scarcity, by norms that say women eat last and least, by memories of earlier medicines that brought side effects. None of that made it onto the PowerPoint.

Talking down isn’t just about vocabulary, though jargon is a big part of it. It’s about posture. It’s the assumption that the communicator’s job is to simplify, not to translate. Simplification often strips away context, uncertainty, and the messy human story of how the science came to be. Translation is a two-way act. It demands listening—to the language, the metaphors, the questions people already carry—and then building a bridge from there.

Why the Deficit Model Lingers

The ‘deficit model’—the idea that public skepticism is really just an information gap—has been picked apart in academic circles for decades. And yet, in practice, it’s still the default. Partly, that’s institutional inertia. Medical colleges, agricultural extension programs, public health campaigns: they’re often built around one-way messaging. The output gets counted—number of camps held, pamphlets handed out. The outcome? Whether trust deepened, whether behavior shifted in any lasting way, that’s harder to measure, so it rarely gets centered.

Another reason is that talking down feels efficient. When you’re responsible for a district of two million people, a radio jingle or a poster can seem like the only viable move. Dialogue is slow. It’s messy. It needs facilitators who are bilingual not just in language but in culture. Yet the evidence is clear: dialogue-based approaches, even when they reach fewer people, often create more durable change because they respect agency. People change their minds not because they were told to, but because they were part of a conversation that made sense to them.

I’ve watched community health workers sit on a charpai with a family and talk about tuberculosis not as a pathogen but as a story—a story of symptoms, of costs, of what the neighbors might say. The science is there, woven in quietly, but the starting point is the family’s own life. That’s talking across. It’s not less scientific. It’s more so, because it accounts for the full ecology in which science actually operates.

The Specific Harm to Health Decisions

Nowhere does the altitude error hit harder than in health. During the COVID-19 pandemic, the world saw both the best and the worst of science communication. In India, messages about masks, vaccines, and social distancing often landed in a language that felt alien to the realities of a single-room home, a shared water tap, or a daily-wage livelihood. The phrase ‘social distancing’ itself was a translation failure—a term that made little sense where physical proximity isn’t a choice but a condition of survival.

When officials spoke, they often invoked ‘the science’ as if it were a single, unchanging authority. But science is a process, full of revisions and arguments. By hiding that process, communicators accidentally set people up for a crisis of faith when recommendations shifted. If you were first told masks were unnecessary, and later told they were essential, you might reasonably conclude someone was lying. A more honest, across-the-table communication would have said: “Here’s what we know today. Here’s what we’re still learning. Here’s what we recommend based on that, and here’s why that might change.” That kind of transparency isn’t weakness. It’s respect.

Vaccine hesitancy, so often painted as ignorance, is frequently a rational response to a history of being talked down to. When a community has experienced medical trials without consent, or had their traditional knowledge brushed aside as superstition, their caution isn’t a deficit. It’s a form of wisdom. Science communication that refuses to acknowledge that history will keep failing, no matter how many studies it cites.

What Talking Across Looks Like

Talking across starts with an uncomfortable admission: the communicator isn’t the only expert in the room. A mother who has managed childhood diarrhea through three monsoons knows something a textbook might miss. A farmer who has watched pest patterns shift over two decades holds data a satellite can’t capture. Their expertise is different, not lesser. When science communication treats it that way, the conversation shifts from instruction to collaboration.

This isn’t about romanticizing local knowledge or tossing out scientific rigor. It’s about putting both on the table and letting them talk to each other. In practice, that means asking questions before handing out answers. It means reaching for metaphors that grow out of people’s lived experience—comparing the immune system to a seed that needs nurturing, or explaining antibiotic resistance through the story of a lock and a key that no longer fit. It means owning uncertainty and cost. “This medicine works for most people, but it might make you feel nauseous. Let’s plan for that.” A sentence like that builds trust far more than a blanket assurance of safety.

It also means designing communication channels that are genuinely two-way. A helpline that only dishes out information isn’t a conversation. A community meeting where the expert speaks and then leaves without staying for tea isn’t a relationship. The best science communicators I’ve seen are known to the community—not just as a voice on a loudspeaker, but as a person who has sat with them, eaten with them, listened to their anger when things went wrong.

Language as a Gatekeeper

In a multilingual country like India, language is both a bridge and a barrier. Science communication overwhelmingly happens in English, or in a formal, Sanskritized register of Indian languages that can feel just as distant. When a doctor uses the term ‘communicable disease’ in a Hindi-speaking village, she might as well be speaking Latin. But the fix isn’t simply to find a simpler word. It’s to find the word that already lives in the community’s vocabulary, and if no such word exists, to build one together.

I once worked on a project about menstrual health. The official materials used the phrase ‘menstrual hygiene management’. The women we spoke with had their own terms—some euphemistic, some direct—that reflected their relationship with the topic: shame, humor, practicality, all tangled up. If we had simply translated the official phrase, we would have missed the emotional texture that shapes behavior. So we started with their words and worked outward. The science was the same, but the door was different.

Language also includes the non-verbal. Tone of voice, body posture, the choice of setting—all of it signals whether the communication is across or down. A lecture delivered from behind a desk, with the audience in rows, is a different event from a conversation under a tree. The content might be identical. The reception won’t be.

The Institutional Fixes We Need

Changing how we communicate science isn’t just a matter of individual sensitivity. It needs institutional shifts. Funding agencies have to reward not just the number of publications but the quality of public engagement. Medical and scientific training must include modules on listening, on anthropology, on the humility to recognize that a community’s rejection of a health intervention is data, not defiance. Evaluation metrics need to move beyond reach—how many people heard the message—to resonance—how many people felt the message was meant for them.

One practical step: embed communication researchers into scientific teams from the start, not as an afterthought. All too often, a study wraps up, a paper gets published, and then a press release is written that strips away all the caveats. Instead, the process of engaging with communities should begin at the research design stage. What questions matter to them? What outcomes would they see as beneficial? This isn’t just communication; it’s better science.

Another step: invest in a cadre of science communicators who come from the communities they serve. Someone who shares the language, the accent, the cultural references of their audience doesn’t need to translate in the same way. Their credibility is already built in. Programs that train local health workers, local journalists, local teachers to be science interpreters are among the most effective interventions I’ve witnessed. They aren’t cheap. They aren’t fast. But they work.

A Personal Note on Failure

I’ve failed at this more times than I can count. Early in my career, I gave a talk on nutrition to a group of mothers. I had my slides, my data, my earnestness. At the end, a woman raised her hand and said, “But what do we cook tonight?” I had no answer. I had talked about micronutrients and dietary diversity, but I hadn’t connected any of it to the budget in her hand, the vegetables in the market, the taste preferences of her children. She wasn’t asking me to simplify the science. She was asking me to make it usable. That’s a different challenge entirely.

That question reshaped how I work. Now, before I prepare to speak with any group, I try to answer three questions: What do they already know and believe? What are the practical constraints they face? And what do they hope I will say—or fear I will say? These questions don’t weaken the science. They anchor it. They turn a monologue into a meeting.

Moving from Transmission to Translation

There’s a beautiful word in Kannada, ‘sambandha’, which means connection or relationship. Science communication, at its best, is about sambandha. It’s not the transmission of facts but the weaving of a relationship between scientific knowledge and human lives. That relationship, like any other, needs time, trust, and a willingness to be changed by the encounter.

When we talk across, we don’t abandon rigor. We don’t pander. We simply acknowledge that science is a human activity, done by humans, for humans, and that its communication has to be equally human. The next time a health official stands in front of a village and wants to talk about iron tablets, I hope they begin with a question: “What do you eat when you are pregnant, and why?” From that answer, everything else can grow.
