I do understand what you mean with bias.. some models where quite stubbornly ignoring things like "I want made in EU - not GDRP compliant - not one office or data center in the EU". I remember this being especially painful for TEM and market email providers. Usually they suck at finding the right pricing data at first try.. so I ended up throwing screenshots of pricing pages. Now that I am writing this up, in some instances manually comparing them would have been faster :D ... The bias might come from the huge amount of US dominance in training data and might not even be intentional. In some niches you don't have many options, that's what I tried leaning on in the article.
