There are three options when you disagree with something on on HN.<p><pre><code>  It&#x27;s Wrong.
  It&#x27;s Correct, and you are mistaken.
  It&#x27;s Correct, but poorly communicated.
</code></pre>
IMO, the poorly communicated issue shows up far more than most people assume.  I have seen several discussion between two experts go X, that&#x27;s wrong Y, that&#x27;s not true X(1)... then after 10 posts they end up agreeing that X ~= Y if Z.<p>PS: This is also far worse on the softer ends of hard science.  Diet, Economics, Climate, Astronomy, and Evolution all suffer from studying complex things with limited ability to experiment.
