Amador Pastor Noheda, the Minister of Education, Culture and Sports in Castilla-La Mancha, has highlighted the critical role of doubt in both science and education. He asserts that acknowledging mistakes is vital for the progression of knowledge.
In a recent reflection, Pastor Noheda noted that few people enjoy discovering they were wrong. It is often challenging to abandon long-held beliefs or accept explanations that contradict previous convictions. However, many of humanity's significant advancements have stemmed from questioning what once seemed unquestionable.
The history of science is intertwined with our errors. For centuries, humanity believed the Earth was the centre of the universe, was unaware of microorganisms, and attributed various diseases to incorrect causes. Knowledge has progressed because individuals have dared to observe reality, formulate new hypotheses, and seek evidence to confirm or refute them.
Pastor Noheda emphasised that one of the great lessons of science is that changing one's opinion in light of new evidence is not a weakness but a sign of intelligence. Scientific knowledge is not built on unshakeable certainties but through a continuous process of research, verification, and revision. Its strength lies not in never being wrong but in having procedures to recognise and correct errors.
This mindset is particularly crucial in today's world, where access to information is unprecedented. The ease of sharing information does not necessarily lead to a better understanding of the world. Social media, the spread of misinformation, and digital environments that reinforce personal beliefs can blur the line between what we wish to be true and what can be proven.
Consequently, learning to differentiate between opinion and evidence, assertion and verified fact, has become a fundamental skill for citizens. Scientific doubt does not equate to distrust of everything or to valuing every opinion equally. It involves asking questions, examining evidence, and accepting well-founded conclusions, even when they do not align with personal expectations.
This educational journey begins in the classroom. Teaching science goes beyond conveying formulas, definitions, or theories; it involves igniting curiosity, learning to observe, posing problems, experimenting, and discovering that explanations can improve when subjected to testing. It is also about teaching students that making mistakes is part of learning and that recognising an error can be the first step towards discovery.
In an era marked by the rise of artificial intelligence, this task has gained even greater significance. While new technologies can provide answers in seconds, no immediate response can replace the effort required to understand. We need to cultivate individuals capable of interpreting information, questioning it when necessary, and using knowledge with their own judgement.
Pastor Noheda pointed out that the aim is not solely to inspire scientific vocations, although that is essential. It is about equipping everyone with the tools needed to navigate an increasingly complex society. Scientific education contributes to forming more autonomous citizens, capable of engaging in debates that impact their health, the environment, technology, and the future of their communities.
In Castilla-La Mancha, this mission connects the daily work of educational institutions with that of universities and research teams. While these are different realms, they share a common aspiration: to expand knowledge and put it to the service of people. Science is not an isolated activity; its discoveries influence our way of life and raise decisions that require ethical reflection.
Every 10 November, the World Science Day for Peace and Development is celebrated, underscoring the importance of research in addressing challenges that no country can solve alone, from diseases to climate change and natural resource management. Scientific cooperation demonstrates that sharing knowledge can bridge divides, reminding us that technological progress alone does not guarantee a fairer society; how we use its results and who benefits from them matters.
Science helps us understand the world, while education, culture, and ethical reflection enable us to ask what kind of world we want to build with that knowledge. Both perspectives are necessary for our advancements to translate into shared well-being, coexistence, and opportunities.
Perhaps one of the most valuable lessons we can learn from science is also one of the simplest: we should not fear acknowledging what we still do not know. The true barrier to knowledge is not the absence of answers but the conviction that we already have all of them.
