Why scientists should be humble Premium
The Hindu
Intellectual humility can play a positive role in science. Intellectual humility is not scepticism. It does not imply doubt. An intellectually humble person may have strong commitments to various beliefs – scientific, moral, religious, political or other – and may pursue those commitments with vigor. Their intellectual humility lies in their openness to the possibility, indeed strong likelihood, that nobody is in possession of the full truth, and that others, too, may have insights, ideas and evidence that should be taken into account when forming their own best judgments.
The virtue of intellectual humility is getting a lot of attention. It’s heralded as a part of wisdom, an aid to self-improvement and a catalyst for more productive political dialogue. While researchers define intellectual humility in various ways, the core of the idea is “recognising that one’s beliefs and opinions might be incorrect.”
But achieving intellectual humility is hard. Overconfidence is a persistent problem, faced by many, and does not appear to be improved by education or expertise. Even scientific pioneers can sometimes lack this valuable trait.
Take the example of one of the greatest scientists of the 19th century, Lord Kelvin, who was not immune to overconfidence. In a 1902 interview “on scientific matters now prominently before the public mind,” he was asked about the future of air travel: “(W)e have no hope of solving the problem of aerial navigation in any way?”
Lord Kelvin replied firmly: “No; I do not think there is any hope. Neither the balloon, nor the aeroplane, nor the gliding machine will be a practical success.” The Wright brothers’ first successful flight was a little over a year later.
Scientific overconfidence is not confined to matters of technology. A few years earlier, Kelvin’s eminent colleague, A. A. Michelson, the first American to win a Nobel Prize in science, expressed a similarly striking view about the fundamental laws of physics: “It seems probable that most of the grand underlying principles have now been firmly established.”
Over the next few decades – in no small part due to Michelson’s own work – fundamental physical theory underwent its most dramatic changes since the times of Newton, with the development of the theory of relativity and quantum mechanics “radically and irreversibly” altering our view of the physical universe.
But is this sort of overconfidence a problem? Maybe it actually helps the progress of science? I suggest that intellectual humility is a better, more progressive stance for science.

This overestimated our collective response capacity while underestimating our psychological tendency to normalise, says Rachit Dubey, assistant professor at the department of communication, University of California.
