The clever title refers to the cold fusion delusion of 1989. Dewdney also takes apart the Biosphere 2 experiment in Arizona in 1991 where the roaches prospered while the people lost a lot of weight and would never have made it without some artificial help from a CO2 "scrubber." Freud, SETI, The Bell Curve believers and neural nets also come under attack as unscientific.
Well, Freud shouldn't even be suspected of being "scientific." In France Freud is read as literature, as is only right. And to attack SETI! Sure it's a long shot, probably a VERY long shot, but what else do we have to do that could possibly reveal anything near as interesting should it succeed? Shame on you, Dewdney. Otherwise, I tend to agree with him, especially about Biosphere 2 which ought to be done again with people who have something close to a clue as to the sort of Herculean dedication and commitment necessary. And bravo for going after the not-too-bright proponents of the antiquated notion of IQ, who think they can define "intelligence," but haven't the foggiest understanding of the real question, "Intelligence for what?" even if they could define it.
In other words, this is a fun book if your ox is not being gored.
