Here is a shorter version of 'There's Not Much Science in Science', given in a slightly different context, for the International Conference on Using Epidemiological Studies in Health Risk Assessments, Berlin Nov. 2023:

One of the main issues is that those who most need certain information are less likely to reach or choose to consult the sources of such information. Nevertheless, this seminar is definitely among the knowledge that we all need.

Check out this new JAMA Network opinion piece from Miguel Hernán Sander Greenland:

“This … proposal is a way to operationalize long-standing calls for shifting research away from testing for effects to estimating effects.”

So true: 'a collection of perfectly-rational learners can in fact ratchet themselves into believing foolish things...agents with most extreme biases tend to dominate how the system evolves' -
as commonly interpreted, 'statistical significance'/'confidence'/NHST form a case study.

Final print version of my rejoinder to comments on 'Divergence vs. decision P-values' is at
onlinelibrary.wiley.com/doi/10.1111/sj…
All commentators agreed the main distinction is important, but raised key issues, esp. the need to be alert to insensitivities of a diagnostic to model violations.

Nice vignette! I would only change 'the coin is fair' to 'the coin tossing is fair': A skilled tosser can alter the frequency of heads if they know the initial side up and catch the toss. That bias can be avoided by tossing the coin into a wall and letting it land on the floor.

R^2 etc is part of my 'statistics is pants' lecture that I have never given but really should write up so I can let the demons out at last. Just so many aspects of stats are historical baggage applied and reapplied to the wrong contexts and goals. Science before statistics.

Here's an item of English that Neyman got right over Fisher (using 'tested' instead of 'null hypothesis'), maybe because English was Neyman's 4th (?) language & he knew how to write clearly for non-native speakers. Yet the stat community ignored his wisdom amstat.tandfonline.com/doi/suppl/10.1…

'If the sample were made enormous enough, the CI would be almost a spike at the point estimate. Yet even modest systematic errors would offset that spike from the true value and ensure the CI would not contain it. Thus any confidence placed in the CI would be false confidence.'

'I think it is crucially important to underscore that compatibility ('confidence') intervals CI only capture uncertainty traceable to sample-size limitations in the form of 'random error'.'

Our new commentary: Discuss practical importance of results based on interval estimates and p-value functions, not only on point estimates and null p-values.

Old news that have apparently not yet spread very far.
