It’s simple: Assume that Braintropolis has put in ZERO effort to fact-check any articles on this site, particularly those that have been contributed or reprinted. You’ve got access to Google the same as I do — look it up. If the info published here is clearly bad, post a comment.
Different story for posts/articles I write myself. If it’s not already indicated in the piece, contact me for source info on any “fact” I’ve presented.
