Re:p-Hacking and False Discovery in A/B Testing by paulddraper on Sunday July 22, 2018 @09:01PM (#17589773)
Agreed. The point of most A/B testing is not to find the best approach per se, but have the greatest number of successes.

If failures essential don't matter (e.g. number of bacteria killed in a petri dish), sure use frequentist p-value.

If failure do matter (e.g. number of patients killed), use Bayesian multi-armed bandit.
