In the early 1990s, a group of medical professionals sparked a revolution by challenging the status quo. They argued that medicine should move away from “intuition” and the opinions of senior doctors—often derisively called “eminence-based medicine”—and instead rely on rigorous clinical trials. This concept, known as evidence-based medicine, was met with fierce resistance from those who viewed it as a threat to their professional autonomy.

Yet, history proved them right. Today, evidence-based practices are considered among the greatest achievements of modern science, standing alongside the discovery of anesthesia and sanitation.

The Current Crisis of Unreason

Despite the success of the evidence-based movement, we are witnessing a modern resurgence of skepticism toward scientific truth. From political leaders dismissing climate change as a “con job” to the dismantling of health agencies and the undermining of vaccine efficacy, the landscape is increasingly dominated by “alternative facts” and misinformation. In the UK, for instance, only 40% of the population views scientific information as generally trustworthy.

However, this isn’t necessarily a sudden, global rejection of science. Rather, it is a setback in a much longer, ongoing process of integrating research into the fabric of daily life.

The Quiet Triumph of Data

While the headlines focus on chaos, a more hopeful trend is unfolding in the background. Evidence is steadily becoming the backbone of various sectors:

  • Education: In England, over 1.5 million children have participated in studies to determine which teaching methods—such as phonics and tutoring—actually improve learning outcomes. Most school leaders now use research to drive their decisions.
  • Economics: Nobel Prize-winning research has demonstrated that anti-poverty programs can be tested with the same rigor as medical drugs. These evidence-driven policies have impacted the lives of at least 850 million people.
  • Technology: The future of information is being shaped by AI. Recently, scientific funders pledged $126 million toward AI systems designed to synthesize vast amounts of research, making rigorous scientific overviews accessible to governments and citizens globally.

Five Strategies to Defend Rationality

When faced with a tide of misinformation, it is easy to feel powerless. However, the battle for truth can be fought through individual and systemic actions.

1. Prioritize Facts Over “Vibes”

The simplest way to fight back is to change your own decision-making process. Instead of relying on gut feelings or social media trends, actively seek out the evidence behind a claim. If a popular assertion lacks credible research to back it up, treat it as nonsense.

2. Verify Through Peer Review

When evaluating a scientific claim, check if the study has been peer-reviewed. While peer review is not a perfect shield against poor-quality science, it is a vital first step in ensuring that research has been scrutinized by other experts in the field.

3. Utilize AI-Powered Search Tools

The sheer volume of scientific literature is overwhelming. New tools, such as the AI search engine Consensus, can help navigate this by searching databases of hundreds of millions of research papers to provide summarized, evidence-based answers to complex questions.

4. Demand Educational Reform

On a systemic level, governments must prioritize critical-thinking curricula in schools. In an era of rampant misinformation, teaching children how to detect “bullshit” and evaluate sources is no longer an elective skill—it is a civic necessity.

5. Practice Intellectual Humility

Science is rarely about providing absolute, unchanging certainties; it is a process of constant refinement, uncertainty, and correction. We must move away from the seductive power of “simple stories” (e.g., “It worked for me!” ) and instead embrace the nuance of data. To win the cultural battle, we must learn to tell the compelling stories of scientific success and progress.

The struggle between evidence and unreason is not a settled conflict; the scales are currently in balance. The direction of the future depends on our collective commitment to truth.

Conclusion
While misinformation poses a significant threat to modern society, the historical success of evidence-based medicine proves that reason can prevail. By demanding rigor, utilizing new technologies, and fostering critical thinking, we can ensure that science remains a guiding force in our world.
