Public Domain Intelligence Tests: Psychometric properties of the Cog15 and ICAR16 cognitive ability scales
The current paper aims to explore the psychometric properties of two public domain cognitive ability scales, Cog15 and ICAR16, and investigate how well they each capture the g-factor in a Swedish sample (N = 428). The motivation for choosing these aims is that public domain, free, and easily accessible intelligence tests are needed for measuring the g-factor. Principal components analysis (PCA), c
