Why so bitter and angry? As far as I can see, his calculations make sense and lead to interesting results. Instead of philosophical nitpicking, why not help him improve his understanding by explaining how you would have calculated&#x2F;formalized&#x2F;modeled this thing, so the scare-quote data &quot;scientists&quot; can learn something?<p>By the way, we definitely don&#x27;t hear all words that these characters speak in their lives. It&#x27;s implied in the story that there are conversations that we don&#x27;t get to see in the actual episodes, but nevertheless these imaginary characters speak a lot more. For example we don&#x27;t see each and every breakfast, lunch and dinner discussion, we don&#x27;t hear all their words in the classroom etc.<p>Now of course the sampling isn&#x27;t random, because the creators obviously &quot;select&quot; the more interesting bits of the characters&#x27; lives, but in statistics we always make assumptions that simplify the procedure but are known to be technically wrong.
