I'm presupposing the contact card has their job position/title, and therefore still answers the question – also presupposing the original (odd) premise of wondering who someone already saved in your phone is.

The Venn overlap between the set of "contacts in your phone" and "people with Wikipedia bios" is likely rather small. Hence why I think it's a faulty premise to complain about Siri defaulting to contact card when these two sets do intersect.
