That is a non sequitur. He&#x27;s talking about grouping countries by specific criteria. To make a code parallel, if you ran<p><pre><code>  select from countries group by police_score;
</code></pre>
and<p><pre><code>  select from countries group by freedom_of_press_index; 
</code></pre>
You&#x27;d expect different results. Maybe there would be a correlation, and the US would be an outlier.
