<p>I think for <em>statistical</em> questions, only when risk is an expected loss does it make sense to tag in a question. To enhance the browsing and tagging experience, it would be useful to rename <code>risk</code> to <code>risk-function</code>.</p>

<p>In the other settings, "risk" tends to be specific to the field and not of particular statistical interest. I would advocate for deleting the risk tag on questions where it is application specific as it is a conflicting use of terms. In some applied questions, people have gotten away with using a tag like <code>finance</code> or <code>biostatistics</code>, so that would seem a better option instead.</p>
