Cultural attractor theory focuses on how ideas being modified as they are transmitted between humans effects cultural evolution. In cultural attractor theory, a cultural attractor is a "destination" that cultural ideas tend to go towards over time. To say that there is an attractor is just to say that, in a given space of possibilities, transformation probabilities form a certain pattern: they tend to be biased so as to favor transformations in the direction of some specific point, and therefore cluster at and around that point. Cultural attraction theory explains why some representations, practices and artifacts are more prevalent and robustly transmitted than others by looking at the micro-mechanisms involved in their transmission.
