Some things should sound absurd (because they aren't true), and some shouldn't. Absurdity bias is where this judgment fails, but if you see absurdly wrong things as non-absurd, that would be the opposite, non-absurdity bias, also a problem.
So, I agree with your main point, but at the risk of being pedantic: absurdity bias is the tendency of a system to judge absurd-sounding statements as false.
Judging as false an absurd statement that turns out to also be false might not be a case where "the judgment fails," but it's just as good an example of absurdity bias as judging as false an absurd statement that turns out to be true.
