Em, you say you can't locate it, and post a link to it!
I have been perusing Donald Hoffman's various papers and video interviews. There's a really nice journalistic piece on him in The Atlantic Monthly
Actually, the anti-realist aspect of his philosophy is much more like Yogācāra than Theravada. But, the issue is that all of Hoffman's work is predicated on evolutionary theory, i.e. that perception is conditioned in such a way as to promote the transmission of the genome. Or at least, that's my reading of it. So it's anti-realist, but I don't think in such a way that has much relevance for Buddhism.
