Trainability:

Linda S. Gottfredson, Why g matters:

>Even up to Wonderlic score 17 (IQ 95), workers tend to need explicit teaching of most of what they need to know, and they do not benefit much from “book learning” training.<

>Employers understandably seek individuals with a greater capacity to learn independently and to work without close supervision, especially for more complex jobs. Indeed, the job descriptions of managerial, executive, and professional workers themselves suggest that high-IQ, self-trainable individuals are essential: that is, individuals who are better able to “learn much on their own” and from the “typical college format” (WPT 26-30, IQs over 110) and to “gather and synthesize information” and “infer information and conclusions from on-the-job situations” (WPT 28 and above, IQs over 116). This roughly 30% of the working population above IQ 110 (25% of the total adult population) would also be essential for training and supervising even the next lower third of the working population, which is “able to learn routines quickly” and with a “combination of written materials and actual job experience” (WPT 20-26, roughly IQ 100-113).<
