Parsimony and the triple-system model of concepts

Abstract

Machery's dismissive position on parsimony requires that we examine especially carefully the data he provides as evidence for his complex triple-system account. We use the prototype-exemplar debate as an example of empirical findings which may not, in fact, support a multiple-systems account. We discuss the importance of considering complexity in scientific theory.

However, it is worth keeping in mind that, even if the heterogeneity hypothesis is true, many people may associate words with one of several existing concepts (e.g., 'fish' with a theory of fish instead of a prototype of fish).…”
