Early theorists inferred the existence of a general intelligence factor, or g-factor, from the observation that performances across different intellectual skills tests were positively correlated. This means that individuals who performed well on one type of cognitive test tended to perform well on others, suggesting an underlying general intelligence that influences performance across a variety of cognitive tasks.
