The importance of IQ for job performance increases dramatically with job complexity—nearly irrelevant for simple jobs, critical for complex ones.
Complex jobs require rapid learning, handling of novel problems, and integration of large amounts of information—all cognitive ability strengths.
A surgeon needs to process complex information under time pressure; a shelf stocker does not. IQ predicts performance to the extent that the job requires cognitive work.
Professional licensing exams (bar, medical boards) have minimum cognitive ability thresholds that predict who will succeed in practice.
Match career complexity to cognitive ability for optimal fit. High IQ individuals may be bored by simple jobs; average IQ individuals may struggle in highly complex roles.
