You&#x27;re asserting a nocebo effect, not a placebo effect, so I don&#x27;t believe your links are relevant. Further, this person is talking about a perceived correlation between an experience and a natural change, not an intervention, which means it may not even be a nocebo effect, but a different category of issue altogether. Given that, I again suggest you cannot actually demonstrate any math on your claim of probability. Again, I think you&#x27;re dressing up your feelings in sciencey talk.<p>Further, your request is nearly tautological. The way that one gets to a big, statistically robust test of a hypothesis is via small stepping stones. E.g., this sort of self-experimentation. If you scoff at everybody doing something small and say, &quot;you&#x27;re probably wrong because there&#x27;s no big evidence&quot;, you decrease the chances of getting the sort of proof that you claim to want.<p>I don&#x27;t think there&#x27;s anything wrong with saying, &quot;personally, I&#x27;d like to see convincing measures of the effect of bright light therapy on mood and intelligence before I adopt this.&quot; But that&#x27;s frustratingly different than your apparent attitude that in 2 minutes of thought you know more about this guy&#x27;s experience than he does.
