This is something the right leaning groups have always been saying, but it is exciting that the article manages to come up with an empirical way to determine the "belief system" of the AI model. People on the left shouldn't rejoice either. The left and the right wing are mostly the same, and both follow similar approaches to marginalize people who they feel are undesirable, so it'll eventually come back to bite the l…
Maybe "thats right-wing rhetoric" has been the method of suppressing what we found uncomfortable.
I'm not sure what you have in mind, but there is definitely a propensity on the left to try to shut down any argument with "that's a right wing position". For example, opposition to CRT was largely a moderate/liberal thing before your average conservative even heard the term, but even then criticism was dismissed with "people who criticize CRT just want to say the N word / get their slaves back / etc". Similarly, conservatives were pretty quick to coin the term "Ferguson Effect" for the pattern of increasing violent crimes in areas that saw large-scale anti-police protests, so naturally academics and the media reflexively dismissed the notion out of hand, but now it seems like crime researchers have largely come around to that viewpoint (to be clear, I'm not criticizing skepticism of conservatives' initial claims, but rather the incurious, out-of-hand dismissal).
