I&#x27;ve always found the &quot;extraordinary claims require extraordinary evidence&quot; meme ridiculous. It defies reason and the scientific method. Extraordinary claims simply need evidence they&#x27;re true. That&#x27;s it. Then, analysis and experiments should be conceived to determine why they contradict the &quot;ordinary&quot; model plus look for sources of error. If error or deceit are found, then the extraordinary claim is rejected. If not, the &quot;ordinary&quot; model is amended or rejected with data from new.<p>That simple. The need for extraordinary evidence seems to just promote orthodoxy. Better to focus on data and methods.
