Hmm Artificial Stupidity haha, I am actively studying for a masters in the artificial intelligence field and never came across that word but I do understand the explanation and it's application. It's all about making machines as human like as possible, like you rightly hinted ,a large percentage of human beings are not perfectly intelligent. There are some elements of stupidity in everyone haha, so it makes sense to try and teach a machine to do that as well.
