Recommender system algorithms typically personalize search results based on similarities to items recently watched, purchased or simply added to a shopping basket. More advanced recommenders suggest based on past history (well YouTube seems to). I don&#x27;t find personalization by similarity offensive. If I watched a Netflix movie starring Sidney Poitier, I&#x27;d expect recommendations to view movies from top Black actors of all time. I see this as ranking on similarity not on racial bias. <a href="http:&#x2F;&#x2F;www.imdb.com&#x2F;list&#x2F;ls051979184&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.imdb.com&#x2F;list&#x2F;ls051979184&#x2F;</a>
