Eat well and take care of yourself. Neurophysiologist Michelle Braun states that one theory for the rise in global IQ is the effects of better nutrition and care in the modern world, especially in the young. Given this possibility, eating properly and good self-care may have a similar effect on you.
Study. According to both neurophysiologist Michelle Braun and James Flynn, Emeritus Professor of Political Studies at the University of Otago in Dunedin, New Zealand, another reason for the rise in global IQ may be an increase in worldwide education, and so, study itself may prove to boost IQ.
Practice problem-solving skills. Clinical psychologist Mikhail Lyubanski at the University of Illinois in Champagne-Urbana states that 97.7 percent of experts on intelligence defined it as problem-solving ability, and so tests of intelligence are likely to measure that ability to at least some degree. Given this idea, then, increasing your problem-solving skills should also increase your score.
Concentrate on solving visual problems, such as those in a video game. According to Dr. Sandra Azar at Pennsylvania State University, the largest increase in global IQ has been on the Ravens test, a test specifically for such visual intelligence. She concludes, therefore, that visual intelligence may rise more easily than other forms of intelligence. Concentrating on this specific type of intelligence may give you the best results for your efforts.
Practice mental tasks with time limits. Psychologist Christopher Richard Brand says that the current rise in global intelligence scores is due to modern people's greater ability to handle mental tasks in a limited time. According to him, prior generations did not learn to do such tasks within a specified time, and so they scored poorly on IQ tests with time limits. However, later generations, again according to Brand, learned to handle time limits and so scored better. Given this idea, you might be able to raise your IQ score simply by learning to work faster.
Listen to Mozart or Yanni before the test. Researcher Christopher F. Chabris has found that the sound of Mozart's music raises IQ scores. Also, in his overview of research into intelligence, Indiana University researcher Martin Jones found that tests with the music of Yanni had a similar effect, but other forms of music did not.
