Science is rigorous when it carefully isolates variables so as not to confuse cause and effect. It considers all the evidence, not just the evidence that supports a favored idea. Its logic is internally consistent and its judgments unbiased. Science is about minimizing bias, and good experiments blind subjects and experimenters to avoid bias. It checks ideas against other experts. And all of this needs to be done in a transparent way—there is no secret knowledge or hidden methods.
