>bold claim that humans are fundamentally irrational

That's bold? Didn't Kahneman and Tversky demolished the idea of humans being rational, empirically, in the 70s? Is there any solid evidence of humans being rational, or even an evolutionary explanation of why that'd happen?

Do we expect other animals to have accurate probability processing psychology, too?

It's bold in a sense that most economic models regarding consumers as rational actors becomes irrelevant or plain wrong. Everyone knows it is a simplification and only partly true, but claiming its dead wrong really often was quite bold.
