No. That meme isn’t “science”, it’s social deference dressed up as epistemology. Science is a method: claims, evidence, measurement, replication, criticism, revision. It is not a priesthood, and it does not come with a caste system where credentials transmute a person’s assertion into fact. If “you’re not a scientist, therefore you’re wrong” were a principle, it would have to be applied retroactively to half of scientific history—because scientists themselves disagreed viciously, continuously, and productively, and “scientists” were often the ones most spectacularly wrong. The first problem is that “scientists” is not a single mind. On any live question—especially where evidence is incomplete, models are fragile, or incentives are political—there are competing hypotheses, competing measurements, competing priors, and frequently competing funding pressures. Appealing to “scientists” as a bloc is a rhetorical shortcut that avoids doing the only thing that matters: specifying the claim, the evidential basis, the uncertainty bounds, and what would falsify it. The second problem is that expertise is domain-specific. A biochemist is not automatically authoritative on climate econometrics. A physicist is not automatically competent on epidemiological policy. Even inside a field, specialisation is narrow. “Scientist” is not a magic word; it is a job description. Arguments still stand or fall on reasoning and evidence, not on the speaker’s badge. The third problem is that “disagreement” isn’t a moral defect; it’s the engine. If you remove disagreement by declaring dissent illegitimate, you don’t get “more science”. You get less. You get conformity. You get publication bias, herding, career risk-aversion, and the quiet burial of anomalies that later become the next correction. That is how a method dies: not by being refuted, but by being enforced. And that is the line between science and scientism. Science invites challenge because it expects to survive it. Scientism demands submission because it cannot tolerate challenge. The moment an institution says “you may not question this”, it has stepped out of science and into ideology, regardless of how many lab coats are paraded in support. Yes, science updates. But updates do not automatically prove virtue; they prove fallibility. “It learned more” is sometimes true—and sometimes the “change” reflects new incentives, different definitions, politicised metrics, or a selective reading of data. The proper response to any claim—scientific or otherwise—is: what is the evidence, how was it measured, what are the error bars, what are the alternative explanations, and what would change your mind? If they can’t answer those questions and instead demand deference, then what they’re selling isn’t science. It’s faith—with a grant budget.
