An all-positive correlation matrix is not evidence of domain-general intelligence

  • Rosalind Arden (a1) and Brendan P. Zietsch (a2)


We welcome the cross-disciplinary approach taken by Burkart et al. to probe the evolution of intelligence. We note several concerns: the uses of g and G, rank-ordering species on cognitive ability, and the meaning of general intelligence. This subject demands insights from several fields, and we look forward to cross-disciplinary collaborations.
