If you read the article there is still plenty of room for those effects to hide in, just like there was before these experiments were done. No one has changed their minds because of this.

You mean the bit where he's working on a version of Orch OR that doesn't cause bremsstrahlung? That's coming up with a new theory. You can always go away and change the theory. This isn't one of those overparameterised theory generators that can trivially explain every possible observation. He will have to materially change it to accommodate this.

And why shouldn't he explore what changes would be needed to accommodate the new evidence? That's not the behaviour of a crank convinced his theory must be right regardless of any evidence. It's just a natural thing to think about when a theory is falsified. He's never described Orch OR as anything more than speculative.

And frankly, what else would you expect him to do? He's 91. It's astonishing that he's still doing this sort of work at all. He's hardly going to start from scratch with a completely fresh theory at this stage, although if anybody could it would be Penrose.
