I've tried over and over to get him to read Dr. Risch's paper and it's extremely bizarre he refuses to do so. He makes all sorts of nonsensical excuses for not doing so but it's obvious he's fearful because it will show he's been wrong the whole time. The paper is air tight. So since he has a problem we with admitting he's wrong, he puts his fingers in his ears and hums loudly until I go away.
