Return of the ego--self-referent information as a filter for social prediction: comment on Karniol (2003).

The protocentrism paradigm of social prediction (R. Karniol, 2003) challenges the egocentrism paradigm tacitly accepted by many researchers. The author reviews the 2 paradigms comparatively by focusing on 3 conceptual and 3 empirical issues. On conceptual grounds, the author suggests that the egocentrism paradigm has been proven useful because of (a) its greater breadth and parsimony, (b) the difficulties in documenting the origin of protocenters, and (c) the indeterminate nature of self-as-distinct tags (which are crucial to protocentrism). On empirical grounds, the author argues that in research on perceptions of self-other similarities, the egocentric process of social projection is well-established. Self-referent knowledge (a) is most readily accessible, (b) receives greater weight in prediction tasks than does other-referent knowledge, and (c) tends to be suppressed only temporarily, with effort, and incompletely.
