 An attractor should not simply be equated with an idea that is psychologically attractive to individuals (Sperber 1996, Buskell 2017). Instead, it is a more abstract notion corresponding to any more-or-less stable outcome of processes of cultural reproduction. Very many different ‘factors of attraction’ can potentially underpin such stable reproduction. For example, if a widely-encountered engineering problem has only a few effective solutions, which are also easy to figure out, then we should expect those solutions to appear again and again, even if individuals are not attempting to copy the innovations of others in detail. In other words, factors of attraction need not be psychological at all, and can instead correspond to physical or ecological constraints. Shared bodies of information, shared preferences and shared emotional or inferential biases might also explain why some cultural variants re-appear with regularity. Some such attractors may be grounded in evolved cognitive dispositions shared by almost everyone. When drawing on these factors of attraction, Sperber and like-minded colleagues have often declared explicit debts to evolutionary psychology (Sperber 1996). Yet attractors can also be more local, corresponding to more narrowly shared cognitive dispositions or biases, common only to small communities. Such dispositions can explain reproduction that is only reliable across narrowly specified cultural contexts. Work in this tradition (e.g. Morin 2016) aims to answer the charge that the cultural evolutionary approach is vacuous via the detailed delineation of such factors of attraction, and their populational consequences, at various spatial and temporal scales.
