I agree we know certain types of masks (N95) are highly effective at preventing spread of airborne illness &lt;i&gt;if&lt;/i&gt; worn properly.&lt;p&gt;But... in the context of the article you referenced, are you prepared to defend the claim that cloth masks which haven&amp;#x27;t been washed for months and are frequently touched, adjusted, and worn incorrectly by kids and teens are &amp;quot;highly effective at preventing spread of airborne illness&amp;quot;?</text><parent_chain><item><author>godelski</author><text>I think what many here and the writers of the article are missing is that you can both be truthful and misleading.

You seem to be basing your analysis that we &amp;quot;know&amp;quot; masking is highly effective. That is not true. The evidence used to justify this policy is low quality(don&amp;#x27;t you remember the CDC hair salon study) and dependent on the precautionary principle. High quality evidence on masking has either low effect sizes or is inconclusive. It is certainly not settled science.</text><parent_chain><item><author>godelski</author><text>I think what many here and the writers of the article are missing is that you can both be truthful and misleading.
