&gt; <i>but it strikes me as more than a little ungrateful to pretend that the experiment was scientifically worthless.</i><p>For better or worse, the amount of information you could extract from an experiment through Bayesian analysis is much larger than what would be allowed as &quot;kosher&quot; science. Regular scientific process is safer because it plays safe - but that&#x27;s also the reason why you aren&#x27;t organizing double-blind studies when your application crashes. You can move faster by careful inference and in case you get stuck or it leads you wrong, you can always revert to a &quot;by the books&quot; scientific method.
