In America, an inordinate number of so-called “scientific” studies are subject to what’s called the “replication (or reproducibility) crisis.” If someone publishes a study that feeds into leftist shibboleths, no matter how poorly done the study is (small sampling, foolish assumptions, bad math, etc.), the results are widely trumpeted and become embedded in the popular consciousness. That the study cannot be replicated (run again from scratch) or reproduced (subject to a new analysis of the study’s data)—and often nobody even tries to do these things—is irrelevant. The narrative overrides the scientific method.
