The phrase "scientific consensus" is often used as if it referred to a poll of researchers' opinions. In practice, scientific consensus describes a quite different phenomenon: a convergence of independent lines of evidence that survive sustained efforts at falsification. The distinction matters because the first definition can be challenged by citing dissenters, while the second cannot.
