Several meta-analyses demonstrate that general mental ability is an accurate predictor of not only job performance, but also with regards to training success. GMA is considered to be a very general mental capability that, among other things, involves the ability to reason, plan, solve problems, think abstractly, comprehend complex ideas, learn quickly, and learn from experience (Gottfredson 1997). Recent developments concerning the correction of indirect range restriction within meta-analyses suggest that reported operational validities of GMA have been underestimated by about 25%.
Gottfredson’s view on what general mental ability is correlates with the fact that GMA will lead to greater success in employee training. A study found that GMA is very closely related to both verbal and numerical ability. This study included results of specific cognitive avility test, supplementary tests as well as structured/unstructured interviews. The same study (that came from primary data) revealed that there GMA is the leading predictor for training success with an operational validity of .65. Also, there appears to be no significant difference between genders.
Time is on my side: GMA, Human Capitlal and Extrinsic Career Success
Generally speaking, no matter what job or culture a certain employee finds themselves in, there is a positive correlation with general mental ability and actual job performance. General mental ability has been shown to predict several work-related criteria and they are as follows: leadership, job satisfaction, creativity, and counterproductive behavior.
Unfortunately there have been relatively few studies that actually link GMA to career success and there have been some studies that credit education with GMA and career success. Others argue that there are several other things other than GMA that have an effect on career success and it’s hard to prove that GMA is the most important. In...
