Attitudes and Attraction: Optimism and Weight as Explanations for the Similarity-Dissimilarity Asymmetry
The positive link between attitude similarity and attraction is one of the fundamental outcomes in social psychology. However, attitude dissimilarity seems to be stronger driver of this relatioship than attitude similarity. The authors review the evidence on this similarity-dissimilarity asymmetry, and discuss two explanations. One is that people generally enter into interactions with optimism, and so supposedly neutral partners are often seen as mildly positive.
