The Flynn Effect

IQ scores have been shown to be associated with such factors as morbidity and mortality, parental social status, and to a substantial degree, parental IQ. While its inheritance has been investigated for nearly a century, controversy remains as to how much is inheritable, and the mechanisms of inheritance are still a matter of some debate.

Environmental factors play a role in determining IQ. Proper childhood nutrition appears critical for cognitive development; malnutrition can lower IQ. For example, iodine deficiency causes a fall, in average, of 12 IQ points. It is expected that average IQ in third world countries will increase dramatically if the deficiencies of iodine and other micronutrients are eradicated.
The average IQ scores for many populations have been rising at an average rate of three points per decade since the early 20th century with most of the increase in the lower half of the IQ range: a phenomenon called the Flynn effect.

The Flynn effect can be explained by a generally more stimulating environment for all people. Aiming to increase IQ would be most likely to produce long-term IQ gains if they taught children how to replicate outside the program the kinds of cognitively demanding experiences that produce IQ gains while they are in the program and motivate them to persist in that replication long after they have left the program.
To rediscover what it means to adapt, could radically change our idea about how to fit in intellectually, emotionally and socially in groups.

Some researchers believe that modern education has become more geared toward IQ tests, thus rendering higher scores, but not necessarily higher intelligence. Perhaps higher intelligence frightens us as we´re headed towards a future of instability, and IQ testing is only challenging our right hemisphere, a neglect in our left wing intellectual hemisphere; sound, creativity and rythm. A test for our literate and linear occidental realm which separates us with vague implications about society´s standard of intelligence. Nonetheless, we´re adapting a layered intelligence based on referances, our database of information, connected to previous impressions which connects through form, feeling, smell and sound. Words are being taught to us through repetition, just as images are repeated to us in a fluctuation, which evidently will lead to a path of destruction, a space shuttled climax of our idea about intelligence. Or it will take on a new form, a transforming intelligence which never reaches a climax, but steadily moves along societies and removes cultural filters and bias.
