   PThe foregoing findings on g's effects have been drawn from studies conducted under a limited range of circumstances--namely, the
   lsocial, economic and political conditions prevailing now and in recent decades in developed countries that allow considerable personal
   afreedom. It is not clear whether these findings apply to populations around the world, to the extremely advantaged and disadvantaged
   gin the developing world or, for that matter, to people living under restrictive political regimes. No one knows what research under
   idifferent circumstances, in different eras or with different populations might reveal.
   
   aBut we do know that, wherever freedom and technology advance, life is an uphill battle for people who are below average in proficiency
   rat learning, solving problems and mastering complexity. We also know that the trajectories of mental development are not easily
   ideflected. Individual IQ levels tend to remain unchanged from adolescence onward, and despite strenuous efforts over the past half a
   scentury, attempts to raise g permanently through adoption or educational means have failed. If there is a reliable, ethical way to
   mraise or equalize levels of g, no one has found it.
   
   LSome investigators have suggested that biological interventions, such as dietary supplements of vitamins, may be more effective than
   oeducational ones in raising g levels. This approach is based in part on the assumption that improved nutrition has caused the puzzling
   lrise in average levels of both IQ and height in the developed world during this century. Scientists are still hotly debating whether
   othe gains in IQ actually reflect a rise in g or are caused instead by changes in less critical, specific mental skills. Whatever the
   ltruth may be, the differences in mental ability among individuals remain, and the conflict between equal opportunity and equal outcome
   opersists. Only by accepting these hard truths about intelligence will society find humane solutions to the problems posed by the
   lvariations in general mental ability.
