The target article ignores the crucial role of correlational methods in the behavioral and social sciences. Yet such methods are often mandated by the greater complexity of the phenomena investigated. This necessity is especially conspicuous in psychological research where its position in the hierarchy of the sciences implies the need for both experimental and correlational investigations, each featuring distinct assets.

Campbell (1960) proposed a “blind-variation and selective retention” model of creative cognition. Subsequent researchers have developed this BVSR model into a comprehensive theory of human creativity, one that recognizes that human creativity operates by more than one cognitive process. The question is then raised of how the BVSR model can be accommodated within the Hull et al. selectionist system.

The Simonton (1991) study of 120 classical composers may provide evidence for the existence of innate talent. A weighted multiplicative model of talent development provides a basis for evaluating the adequacy of Howe et al.'s conclusions.

Cultural evolution may be even more prolific in the generation of new forms than is biological evolution – especially when it takes the form of creative genius. Yet evolutionary theories have tended to overlook the factors that might select for outstanding individual creativity. A recent dual-inheritance theory is outlined and then integrated with the niche-construction theory of Laland et al.
