<p>There are currently 123 threads tagged with <a href="https://stats.stackexchange.com/questions/tagged/confidence" class="post-tag" title="show questions tagged &#39;confidence&#39;" rel="tag">confidence</a>.</p>

<p>In the next several days I plan to look through <a href="https://stats.stackexchange.com/search?tab=newest&amp;q=%5bconfidence%5d%20-%5bconfidence-interval%5d%20-%5binterval%5d%20-%22confidence%20interval%22%20-%22confidence%20intervals%22%20-%22confidence%20level%22%20-%2295%25%22%20is%3aquestion">all 30-40 that are not explicitly about CIs</a> via search</p>

<pre><code>[confidence] -[confidence-interval] -[interval] -"confidence interval"
-"confidence intervals" -"confidence level" -"95%" is:question
</code></pre>

<p>I will retag those that are not about confidence intervals. For the ones that are about "confidence" in an output of a classifier I am/will be using the <a href="https://stats.stackexchange.com/questions/tagged/uncertainty" class="post-tag" title="show questions tagged &#39;uncertainty&#39;" rel="tag">uncertainty</a> tag, as suggested in the @AdamO's answer.</p>

<p>UPDATE: the above search yields zero results. All the remaining [confidence] threads are about CIs. <strong>Hence, we can now make a synonym <a href="https://stats.stackexchange.com/questions/tagged/confidence" class="post-tag" title="show questions tagged &#39;confidence&#39;" rel="tag">confidence</a>$\to$<a href="https://stats.stackexchange.com/questions/tagged/confidence-interval" class="post-tag" title="show questions tagged &#39;confidence-interval&#39;" rel="tag">confidence-interval</a> and merge it straight away.</strong></p>

<p>Please vote for this synonym here: <a href="https://stats.stackexchange.com/tags/confidence-interval/synonyms">https://stats.stackexchange.com/tags/confidence-interval/synonyms</a> if you have >=2.5k rep and >=5 rep in the [confidence-interval] tag.</p>

<p><strong>UPDATE2 (Jan 26): Synonym implemented via voting without mod intervention.</strong></p>
