Metascience, according to this article in Nature, is “the science of science … It has its roots in the philosophy of science and the study of scientific methods” with a primary focus being the study of the reproducibility of experimental findings.

The article points out “the decline effect, an idea … that the size of an effect decreases over repeated replications,” acknowledges experimenter expectancy effects and the power of double-blinding and expects that “self-examination can only strengthen the scientific process for all.”

And when we try something new in our testing, we subject that thing to testing, don’t we? Don’t we?
