What is the purpose of the IQ test?
The purpose of the IQ test is to give an overall impression of the conscript's general ability to assimilate military education (Ross, 1988). The IQ test used in our study had 4 different parts: (A) instructions—testing verbal ability to follow instructions, where logical inductive ability is also tested (40 items), (B) concept discrimination—testing both logical inductive and verbal ability by selecting which 1 of 5 words that does not agree with the others conceptually (40 items), (C) paper form board—testing spatial ability by choosing which group of geometric figures make up a presented figure (25 items), and (D) technical comprehension—testing technical ability by selecting 1 of 3 options that to answer a question related to a picture illustrating a basic technical or physical property (52 items) (Carlstedt and Mårdberg, 1993). Optically readable response sheets were used and slight time pressure was applied (Rönnlund et al., 2013). Instructions were given to the conscript prior to each subtest. Scrutiny of the different subtests has shown high intercorrelations, which is why interpretations of differences in results should be made with caution. Test–retest reliability has been estimated at 0.81, with a time interval of 1 to 3 years, and there is acceptable predictive validity for being educable within the military (Ross, 1988).
How does intelligence affect health?
One suggested explanation for the association between intelligence and health is that cognitive skills enhance possibilities to make healthy lifestyle choices. Cognitive ability has been found to be associated with several health-related behaviors, such as smoking, food intake, and physical activity (Batty et al., 2007b,c; Hemmingsson et al., 2008). The scientific literature on intelligence and alcohol consumption in adolescence, measured as total intake and type of drinking, is scarce. A twin study from the United States showed that a high IQ assessed at age 17 was associated with heavier alcohol use as measured by an alcohol use composite, taking into account symptoms of alcohol abuse/dependence, number of intoxications, frequency of use and number of drinks during a year, and maximum number of drinks within 24 hours (Johnson et al., 2009). A study from Switzerland investigated how IQ test results from conscription were associated with frequency of drinking, defined as nondrinking, rare drinking (1 to 5 times/y), occasional drinking (1 to 5 times/month), moderate drinking (1 to 5 times/wk), and daily drinking. It showed that high performance on IQ tests had a positive association with moderate drinking (Muller et al., 2013). In the 1970 British Cohort Study, it was found that higher childhood mental ability was associated with higher alcohol intake as an adult (Batty et al., 2008). Another study from the United States, of a population 14 to 21 years of age, showed, on a measure of verbal intelligence, that lower verbal intelligence was associated with lower alcohol consumption, but also with a higher risk of alcohol-related problems among those who consumed alcohol (Windle and Blane, 1989).

Why is my IQ lower than my actual IQ?
The reason why scores might be lower is that the brain is not yet fully developed (for males until they are 25!) and that environmental factors have not yet had time to express themselves fully.
How reliable are IQ measurements?
IQ scores obtained through rigorous tests delivered by a trained psychologist or psychometrician are usually the most reliable and will provide with information about on how your cognitive abilities compare to the general population other than the IQ score (e.g. spatial reasoning, verbal skills, auditory processing, short and long-term memory, etc. Standardized tests taken as part of a high-IQ society exam (e.g. Mensa) are also quite reliable. Finally, there are different kinds of free and paid online tests with varying degrees of reliability. In all cases you have to assume some measurement error, usually a 3-point measurement error is considered, so if your obtained score is 115 it is very likely that your true score is between 112 and 118. Taking several different tests at different times and taking their average is usually the best way to get a more reliable estimate of your general intelligence.
What is IQ?

What is the standard deviation of IQ test?
Most tests are standardized so that their mean score is 100 and their standard deviation is 15 making the calculation of a percentile trivial through the use of the normal distribution CDF. Some tests use a different standard deviation: 16, 24, etc. which is why our IQ calculator allows you to specify the standard deviation of the test that produced the intelligence quotient score.
