Seven in ten citizens said they didn't understand how to protect themselves.
En medio de una de las peores crisis sanitarias del mundo moderno, Perú descubrió que los muros y las multas no bastan para cambiar el comportamiento humano. Con la mayor tasa de mortalidad per cápita del planeta y un colapso económico sin precedentes, el país pagó el precio de ignorar décadas de investigación en ciencias del comportamiento. Mientras naciones con sistemas de salud igualmente frágiles lograron contener el virus mediante comunicación estratégica y persuasión informada, Perú apostó por la intuición y el paternalismo, y perdió.
- Siete de cada diez peruanos declararon en agosto de 2020 no haber recibido información suficiente para protegerse, una señal de alarma que el gobierno no supo leer a tiempo.
- Las campañas oficiales que tildaban a los ciudadanos de 'irresponsables' desencadenaron exactamente lo contrario de lo que buscaban: la investigación predice que la vergüenza pública erosiona la cooperación colectiva.
- Países con infraestructuras sanitarias comparables —Tailandia, Malasia, Ruanda— lograron resultados radicalmente mejores al anclar su comunicación en evidencia conductual, no en decretos.
- La ciencia del comportamiento ofrece herramientas concretas: mensajes respaldados por autoridades de confianza, normas sociales que reflejen la mayoría cooperadora, y apelaciones emocionales calibradas para no generar rechazo.
- La pregunta que queda abierta no es técnica sino política: cuando llegue la próxima crisis, ¿elegirá el Estado peruano la evidencia o volverá a confiar en la intuición?
Perú llegó a la pandemia con una desventaja que no tenía que ver con el virus. El gobierno eligió la intuición sobre la evidencia, el paternalismo sobre la persuasión, y los resultados fueron devastadores: 1.077 muertes por millón de habitantes —la peor tasa de mortalidad per cápita del mundo según la Universidad Johns Hopkins— y una contracción económica del 30,2% en el segundo trimestre de 2020, la más severa registrada globalmente. Una cuarentena de las más estrictas del planeta no contuvo la epidemia, pero sí destruyó la economía.
Lo más revelador no son los números en sí, sino el contraste. Tailandia, Malasia y Ruanda operaban con sistemas de salud tan precarios como el peruano, y aun así gestionaron la crisis con resultados incomparablemente mejores. La diferencia no estaba en los hospitales ni en el presupuesto. Estaba en cómo los gobiernos se comunicaban con sus ciudadanos.
El cerebro humano no es un receptor pasivo de información. Llevamos sesgos cognitivos que nos empujan a preferir recompensas inmediatas sobre beneficios futuros inciertos, a desarrollar exceso de confianza tras experiencias sin consecuencias, y a filtrar los mensajes que contradicen nuestras creencias previas. Estos no son defectos morales; son características documentadas de la cognición humana. La pregunta es si un gobierno las reconoce o las ignora.
Perú las ignoró. La campaña 'No Seamos Cómplices' intentó movilizar mediante el miedo y la culpa, pero la evidencia sobre el miedo es ambigua: puede funcionar a corto plazo o puede generar rechazo y negación. Lo que sí funciona, según la investigación conductual, es mostrar que la mayoría ya está cooperando, entregar información en el momento preciso en que se necesita, facilitar la decisión correcta y hacerla atractiva. Un estudio controlado realizado por Heurística demostró que los mensajes respaldados por autoridades sanitarias y que ofrecían contrastes concretos entre conductas correctas e incorrectas lograban cambios de comportamiento medibles.
La lección no es abstracta. La próxima pandemia llegará. La próxima crisis exigirá que millones de personas cambien hábitos que les resultan naturales y cómodos. Cuando eso ocurra, Perú tendrá que elegir entre repetir el error o construir sobre la evidencia.
Peru entered the pandemic with a catastrophic disadvantage that had nothing to do with the virus itself. By August 2020, five months into the crisis, seven out of ten Peruvians believed they had received insufficient information about how to protect themselves. The government had chosen intuition over evidence, paternalism over persuasion, and it was costing lives.
The numbers tell a brutal story. Peru recorded 1,077 COVID-19 deaths per million inhabitants—the worst per-capita mortality rate in the world, according to Johns Hopkins University. The government imposed one of the strictest lockdowns anywhere, yet the virus spread anyway. The economic cost was staggering: a 30.2 percent contraction in the second quarter of 2020, the worst economic collapse recorded globally. A strict quarantine that failed to contain the epidemic but devastated the economy—a failure that seemed inevitable given Peru's fragile health infrastructure. Except it wasn't inevitable. Thailand, Malaysia, and Rwanda all operated with health systems as precarious as Peru's, yet they managed far better outcomes. The United States, Britain, and Spain had developed infrastructure and still struggled. The difference was not money or hospitals. It was how governments talked to their citizens.
Countries that succeeded deployed aggressive testing, tracing, and isolation—but they did something else too, something less visible but equally crucial. They changed behavior. They persuaded millions of people to wear masks, maintain distance, practice hygiene, and avoid gatherings. They did this not through force alone but through communication grounded in decades of behavioral science research. The human brain, it turns out, is predictably irrational in ways that can be anticipated and addressed.
We all carry cognitive shortcuts that served us well in small tribes but betray us in a pandemic. We chase immediate, certain rewards—visiting a friend, going to a crowded market—over distant, uncertain benefits like reducing transmission risk. We develop overconfidence: nothing bad happened the last three times we went out, so it must be safe. We filter information through our existing beliefs, dismissing warnings that contradict what we already think we know. These are not character flaws. They are features of human cognition, documented across psychology, economics, and neuroscience. The question is whether a government acknowledges them or ignores them.
Perú's government ignored them. Instead of designating a trusted scientific voice to deliver clear, consistent messages, it deployed paternalistic campaigns that backfired. When officials repeatedly labeled citizens as "irresponsible," they triggered a psychological response the research predicted: people stopped cooperating. Humans are conditional cooperators. We do what others do. When we see most people following the rules, we follow them too. When we see rule-breakers punished or shamed, we become less likely to cooperate ourselves—a phenomenon so robust it appears across cultures. The government's strategy of public shaming worked against its own goals.
The "No Seamos Cómplices" campaign tried to motivate compliance through fear. Fear can work in the short term, but the evidence is ambiguous. It can also trigger rejection, a sense of lost control, a retreat into denial. Peru needed messages built on what behavioral economists call EAST: social proof (showing that most people were cooperating), timeliness (delivering information when people needed it), ease (making the right choice simple), and appeal (making it attractive to follow along). It needed constant, small-scale experimentation—testing messages on limited samples, measuring what worked, refining, deploying. This sounds like a luxury in a crisis. It is actually a necessity. When so much depends on voluntary compliance, you cannot afford to guess.
One controlled study, conducted by Heurística, found that messages backed by health authorities and offering concrete contrasts between correct and incorrect behavior shifted behavior significantly. This is not theoretical. This is what works. As Peru moves forward, the question is whether it will learn. The next pandemic will come. The next crisis will demand that citizens change their behavior in ways that feel unnatural and costly. When it does, Peru will have a choice: follow intuition, or follow evidence.

The Hearth Conversation Another angle on the story
Why did Peru's lockdown fail so dramatically when other countries' lockdowns worked?
The lockdown itself wasn't the problem—it was the communication around it. Peru locked down hard but never convinced people why. Seven in ten citizens said they didn't understand how to protect themselves. You can't enforce behavior change through force alone.
But surely people understood they should wear masks and distance?
Understanding and doing are different things. Our brains are wired to seek immediate rewards over distant ones. Visiting family feels good now; avoiding infection is a maybe later. That's not stupidity—that's how human brains work. Countries that succeeded acknowledged this and designed messages around it.
What would that look like in practice?
Pick one trusted scientist to deliver all the main messages, not rotating officials. Show people that most citizens are cooperating—not by shaming the few who aren't, but by highlighting the cooperative majority. When Peru kept calling people irresponsible, it actually made cooperation worse.
How does that work psychologically?
We're conditional cooperators. We do what we see others doing. If you keep saying people are breaking the rules, people stop believing the rules matter. You've poisoned the social norm.
What about fear-based campaigns?
Fear can motivate short-term compliance, but it's a double-edged sword. It can also trigger rejection, denial, a sense of helplessness. The research is mixed. That's why you need to test messages on small groups first, measure what actually works, then scale it.
Peru didn't do that?
No. It followed intuition and paternalism. It guessed. And when you're asking millions of people to change their behavior during a pandemic, you don't get a second chance to guess right.
