<p>When you ask how to respond you already close the option for the answer to say they disagree with the notion and in fact think frequentism is intrinsically flawed. It doesn't get to the point that it's opinion based, but I find it's easier to ask: &quot;Is frequentism flawed?&quot; or &quot;Why is frequentism valid?&quot; - answers naturally come up with arguments to why frequentism is or isn't invalid.</p>
