 Koenig et al. showed the correlation between g derived from the Armed Services Vocational Aptitude Battery (ASVAB) and the ACT in a sample of 1075 participants was 0.77.

It is generally accepted that a single underlying factor of cognitive abilities exists, known as the general intelligence factor or, simply put, the ‘g’ factor. This factor of measurement is believed to correlate to measurements of more specific forms of cognitive abilities like reasoning, language, memory, visual perception, auditory perception, creativity and speed.

Solving for ‘g’: Getting value from cognitive ability tests

General cognitive ability tests are used to assess a person’s learning ability and are among the best predictors of training success and job performance across all job levels and industries. People with higher scores on these tests tend to catch on quickly, figure things out on their own, and make sense of things in relatively short order.
