If a student contracted and was asymptomatic, not shown here, etc.&lt;p&gt;A great many of the pro-mask papers in 2020 that claimed to &amp;quot;prove&amp;quot; that masks work started from self-reported data (the infamous &amp;quot;hairdressers&amp;quot; CDC report comes to mind...if a customer was asymptomatic, they were ignored; there was no control, so it&amp;#x27;s impossible to know what would have happened otherwise; etc.) The standards for &amp;quot;proof&amp;quot; across the pandemic have been dismally low, and tribalism and politics have supplanted science.&lt;p&gt;The difference here is that we actually have examples from across the globe where kids &lt;i&gt;weren&amp;#x27;t&lt;/i&gt; masked in schools, and no matter how you look at it, it doesn&amp;#x27;t seem to make much of a difference. If we&amp;#x27;re going to be skeptical (we should!) let&amp;#x27;s be skeptical of &lt;i&gt;every claim&lt;/i&gt;, and demand proof of effectiveness for our medical interventions before imposing them across all of human society.</text><parent_chain><item><author>hackersword</author><text>Have you looked at the actual report and not the anti-vax site summation of the report?&lt;p&gt;&amp;gt;.
