For information: Scientific Consensus: What It Means and Why It Matters | The Science AuthorityConsensus is a political term, not a scientific one. So you reinforce the fact that you're stupid, as well as tired. And I am 6 years older than you, junior.
Scientific consensus sits at the center of how knowledge gets translated into policy, medicine, education, and everyday decisions — and it's one of the most misunderstood concepts in public discourse. This page explains what consensus actually means in a scientific context, how it forms, where it applies, and — critically — where it doesn't. The distinction matters more than most people realize.
Definition and scope
Scientific consensus is not a vote. It isn't a committee decision, a press release, or the loudest voice in a discipline. The National Academies of Sciences, Engineering, and Medicine describes it as the collective judgment, position, and opinion of the community of scientists in a particular field of study — a convergence of independent lines of evidence pointing in the same direction.That last part is the key mechanism. Consensus doesn't emerge because researchers agree with each other. It emerges because separate research teams, using different methodologies, analyzing different datasets, in different countries, keep arriving at the same conclusions. Human-caused climate change, vaccine safety, the age of the universe at approximately 13.8 billion years, the germ theory of disease — these aren't dogmas. They're the current state of accumulated, cross-checked, replicated knowledge.
