Wikipedia is an amazing wonder of the internet. I could spend ten hours a day reading deep into topics and related topics I only learned because of the initial curiosity I had. But that's beside the point. There is such thorough coverage of all topics of every field so I would indeed expect that judges are using it to look things up because of how convenient it is.
The problem is that in certain subjects (especially those with a potential ethical dimension like social and cultural pages) there is significant bias towards the left (I say that as a left-leaning person).
That's not healthy at all when being used as a resource without awareness and significant caution.
