The book was written in 1987, which is before Kahneman and Tversky's experiments were popularized (at least outside of academic Psychology.)

That said, bias is a general term, and "intellectual phase lock" as described here is a more specific example. The modern terms would probably be "anchoring", "confirmation bias", "courtesy bias", which slice up the space in a slightly different way.

It is a particular type of bias with an identifiable cause and specific remedies -- remedies that, despite what this exerpt might suggest, are widely known and practiced. On the other hand, Alvarez's term is idiosyncratic (possibly inspired by his WWII work on radar?) and not, apparently, widely used. Related terms: doctrine, received wisdom?
