Cognitive psychologist: The argument against IQ as a hereditary trait that is fixed throughout one's lifetime ignores the evidence of eye orientation  That is, there is a high correlation between the speed in which a person's eyes orient towards a stimulus and that person's IQ  Specifically, an experiment measured the number of milliseconds subjects required to orient their eyes to the where on a large screen a word was flashed
The study found that the more rapid the response the higher that person's IQ
The speed in which a person orients his or her eyes towards a stimulus is a skill that cannot be modified by experience.
