ABSTRACT
To many students of psychology today, nothing better represents the cold hand of psychological determinism than does IQ (e.g. Rose, Kamin and Lewontin, 1984). In the 1980s we can all smile quite genially at the Freudian idea that selfeontrol depends on potty-training, and at any behaviourist notion that our persistent loyalty to our friends might be traced to the partial-reinforcement schedules upon which they had once put us. Yet IQ still represents a hurdle to be surmounted as we try to insist that psychology (with whatever assistance from radical politics) can readily make Utopian change possible in human affairs.
