<p>I did this on Math.SE yesterday.</p>
<p>My question was (correctly) closed as a duplicate. Because I had made some incorrect assumptions in the question, I decided that it would be best to delete it and keep newcomers from reading the incorrect information and skipping the comment pointing out the mistake (without giving a correction).</p>
<p>I would expect Math.SE to respect my decision to delete, and I expect the same from Cross Validated.</p>
