Dr. Rob Whitfield pushes back on experts making overconfident claims about immunity. He walks through how T-cells mature in the thymus and learn to distinguish self from non-self, then argues that many aspects of immune function remain uncertain and deserve more humility in scientific discussion.
it just highlights it. We just don't know enough. Yeah, it's very— I think it's just super, like, when I hear people talk about the immune system, I just, I'm baffled by, like, the certainty with which they say things, which, you know, is not— like, you can't prove it. Yeah. And each— the paper I, I commented on, uh, from Denmark, somebody wrote a commentary about it, said you can't say this. Yeah. And I'm like, well, why? Yeah, what is your interest in saying that they can't say that? And it was somebody who was a composite tissue— I'm sorry, composite tissue allograft transplantation expert. And I was like, okay. So your body has T cells that go through training in your thymus. You recognize self versus not. Everything, you know, that's what protects you. And these things, T cell receptors, are all over the body on our cell types and they protect us.
