Note that his mistake was simply referencing the wrong paper, there are newer papers which do confirm what he said which he has referenced in this correction video.
And this is what honest people do when they've made a mistake. They don't just double down on it or just declare other people liars or wrong or having some ulterior motive without basis. You know it's without basis because when asked to elaborate they can't. They just change the subject, repeat the accusation, still without basis, or chuck around pop psychology terms.
