"The misuse of statistical significance . . ."

Post by xouper » Fri Mar 22, 2019 11:00 pm

The misuse of statistical significance has done much harm to the scientific community and those who rely on scientific advice.
That's from a recent paper in Nature:

https://www.nature.com/articles/d41586- ... fingthread

For those who like pictures thought provoking graphs, the paper also has these:

I mention this paper because I assume it's a topic that might be of interest to non-scientists who are students of critical thinking, including statistical fallacies. But that doesn't necessarily mean it will generate much discussion here on this forum, since the number of active participants here is not statistically significant. :wink:

I shall defer to Witness's preference, which seems to be to not delete it.

Do I still get to spend the night in the box?

Another discussion on StackExchange: https://stats.stackexchange.com/questio ... -comment-i

Where I found a link to this interesting Wiki page: https://en.wikipedia.org/wiki/Replication_crisis
Quoting the introduction:
The replication crisis (or replicability crisis or reproducibility crisis) is an ongoing (2019) methodological crisis primarily affecting parts of the social and life sciences in which scholars have found that the results of many scientific studies are difficult or impossible to replicate or reproduce on subsequent investigation, either by independent researchers or by the original researchers themselves. The crisis has long-standing roots; the phrase was coined in the early 2010s as part of a growing awareness of the problem.

Because the reproducibility of experiments is an essential part of the scientific method, the inability to replicate the studies of others has potentially grave consequences for many fields of science in which significant theories are grounded on unreproducible experimental work.

The replication crisis has been particularly widely discussed in the field of psychology (and in particular, social psychology) and in medicine, where a number of efforts have been made to re-investigate classic results, and to attempt to determine both the reliability of the results, and, if found to be unreliable, the reasons for the failure of replication.
