I think you are missing the point. With academic publication bias, sometimes an unbiased coin gets heads 600 times by chance. Those studies get published. But, if you ran the test again, you might only get 525. That study won’t get published.

And, in opposition to your assumption: there is nothing to prevent A/B tests being published with high academic standards— like a low p value and tons of n. In an academic context, that’s just fine— it’s a small but significant effect.

A/B tests are simply controlled experiments—which are the gold standard of scientific evidence generation in psychology. My point is that the main generators of this evidence are only permitted to use this evidence to inform commerce not public knowledge. That is a loss for science and public policy, in my opinion.
