<p>Turns out that we have a <a href="https://stats.stackexchange.com/questions/tagged/theory" class="post-tag" title="show questions tagged &#39;theory&#39;" rel="tag">theory</a> tag. Its wiki excerpt says </p>

<blockquote>
  <p>For questions about statistical theory. Always include a more specific tag as well.</p>
</blockquote>

<p>This means that it is a meta tag by definition. And so <a href="https://stats.meta.stackexchange.com/questions/264">it should go</a>. It does not seem to add any value, is used inconsistently, and is only causing confusion.</p>
