Before assuming that confidently wrong people are simply undereducated, check yourself. Lord Kelvin, aka William Thomson, was one of the most brilliant physicists of the 19th century and the man who essentially revolutionized thermodynamics. There is even a unit of measurement named after him, so it is safe to say the man had something going on upstairs.
That same man declared confidently that "radio has no future," insisted that "X-rays will prove to be a hoax," and stated with full conviction that "flying machines larger than air are impossible." All three of those things now exist, and we can't even imagine a reality without them. Genius comes with no immunity to being spectacularly, historically wrong, and the sooner we realise that, the better.
You might want to argue that Lord Kelvin was simply a product of his times, so what excuse did Steve Ballmer, CEO of Microsoft, have? He watched Apple announce the original iPhone in 2007 and laughed on camera. In a USA Today interview that has since been viewed millions of times, probably on the very device he was mocking.
"There's no chance that the iPhone is going to get any significant market share. He doubled down on Microsoft's existing mobile strategy, missed the smartphone revolution entirely, and the whole episode is widely credited as one of the most expensive wrong opinions in corporate history. The iPhone currently holds around 60% of the US smartphone market. No chance, indeed.
The reason people dig in rather than fold is not stupidity; it is neuroscience. Psychologist Mike Brooks Ph.D. explains that the brain processes being wrong as a direct threat to identity and survival, triggering the same defensive response as a physical threat.
"When our personal or social identity is at stake," he notes, "we are more likely to distort reality and deny that we are wrong to defend such identities." So the person in the comments getting increasingly unhinged might seem stubborn, but their brain has classified the correction as an onslaught and is just doing what nature intended it to.
The frustrating irony is that being wrong is actually one of the most useful things a person can do, if they let it be. ASCD, formerly the Association for Supervision and Curriculum Development, identifies mistakes as a critical tool for deeper learning, noting that a positive mistake culture can reinforce metacognition, build resilience, and open up learning that correct answers simply cannot.
They also say we should strive towards creating a "positive mistake culture," where we don't get dismissed for being wrong. The problem is that this only works if the person experiencing the mistake is willing to sit with the discomfort of it rather than immediately launching a counteroffensive in a comment thread.
But one burning question remains unanswered. Are men or women more likely to have all the audacity in the comment section? Behavioral studies examining the effects of testosterone found that higher levels are associated with decreased cognitive reflection and an increased intuitive feeling of being correct.
This does not mean that men are wrong more often, but it does suggest they may be quicker to form a snap judgment and slower to question it afterward. The double-checking step, the one where you pause and think "wait, am I sure about this," is the exact step that gets skipped.
What happens after the mistake is also telling. Sociological and psychological research notes that men tend to frame past errors briefly and philosophically, filing them under "learning experience" and moving on. Women are more likely to give detailed, emotionally expressive accounts of where things went wrong.
Neither approach is objectively better, but one of them does produce significantly more self-awareness about the mechanics of the mistake, which is probably useful information the next time the urge to post with absolute certainty arrives.
