Editing Matching hypothesis (section)

=== Murstein (1972) ===
Murstein also found evidence that supported the matching hypothesis. Photos of 197 couples  in various statuses of relationship (from casually dating to married), were rated in terms of attractiveness by eight judges. Each person was photographed separately. The judges did not know which photographs went together within romantic partnerships. The ratings from the judges supported the matching hypothesis.<ref name="Murstein 1972">{{cite journal|last=Murstein|first=Bernard I.|title=Physical attractiveness and marital choice.|journal=Journal of Personality and Social Psychology|date=1 January 1972|volume=22|issue=1|pages=8–12|doi=10.1037/h0032394|pmid=5013362}}</ref>

Self-perception and perception of the partner were included in the first round of the study; however, in the later rounds they were removed, as partners not only rated themselves unrealistically high, but their partners even higher.<ref name="Murstein 1972" />
