I notice that Sarsons&#x27;s paper says on the very first page:<p>&quot;NOTE: Very preliminary – please do not cite without permission. Comments welcome.&quot;<p>I wonder if Cowen sought permission or just ignored that sentence?  I am aware that linking to something from a blog isn&#x27;t exactly the same as citing it (presumably Sarsons is trying to discourage citations in other papers), but Cowen could have mentioned, but didn&#x27;t mention, the preliminary nature of the paper when quoting the abstract.
