Exercise: Critique the model response

The replication crisis first emerged in 2011 when John Ioannidis and his colleagues in the Reproducibility Project attempted to replicate 100 psychological studies and succeeded in replicating only about 36 to 39 percent with similar effect sizes.

A retraction of a scientific study does not necessarily mean that the study was fraudulent or that data was fabricated. Often, the reason lies in data processing errors, lost data, or ethical violations that lead to retraction even though the conclusion may be correct.

Scientific consensus is a measurable quantity: when 97 percent of scientists agree on an epistemic claim, it is considered established and requires no further criticism or revision.

A citation tree is a useful way to trace the origin of a claim: if paper A cites paper B which cites paper C, the claim can be traced back to the original study to assess whether it has been replicated or is a single research case.

Research on sleep and academic performance strongly shows that students who sleep less than eight hours a night perform about 30 percent worse on exams than students who get a full eight hours of sleep, and this applies regardless of age and subject.

When a study is published in a peer-reviewed journal, it has already undergone rigorous criticism and error-checking, so the reader does not need to make their own assessment of the strength of the data or the methodology.
