Based on [[cognitive consistency]] theories, difference in attitudes and interests can lead to dislike and avoidance whereas similarity in attitudes promotes social attraction.<ref name=singh2000>{{cite journal | doi = 10.1348/014466600164426 | last1 = Singh | first1 = R. | last2 = Ho | first2 = S.

The studies by Jamieson, Lydon and Zanna (1987–88) showed that attitude similarity could predict how people evaluate their respect for each other, and also predict social and intellectual first impressions – the former by activity preference similarity and the latter by value-based attitude similarity.<ref name=jamieson1986>{{cite journal | doi = 10.1037/0022-3514.53.6.1052 | last1 = Jamieson | first1 = D.

Although attitude similarity and attraction are linearly related, attraction may not contribute significantly to attitude change.<ref>{{cite journal | doi = 10.1037/h0028429 | last1 = Simons | first1 = H.
