It&#x27;s a common misconception that &quot;algorithmically selected&quot; implies a certain non-bias.  Perhaps this myth stems from examples used to explain simple algorithms (e.g. drawing straws, or pulling names from a hat).<p>Complex algorithms certainly do exhibit bias, and not only that - it&#x27;s intentional.  The whole point of a &quot;trending&quot; topic is to discriminate (i.e. inject bias) trendy topics from less trendy topics.<p>So you&#x27;re talking about only adding the bias you want it to add - but I hope you can imagine that&#x27;s an impossible cause to get 100% correct.  There&#x27;s no rigorous definition of trending; nor is there a rigorous definition of the topics to be selected from, nor are lots of other matters here rigorously defined.  There&#x27;s no way you&#x27;re going to do better than some fuzzy algorithms trained on real data.
  Critically, that tends to mean real data generated by... biased humans.
