Experimental research focusing on consensually non-monogamous relationships is lacking. This study examined perceptions of relationship satisfaction of participants (N = 321) randomly assigned to conditions in which they were presented with either a passage depicting a monogamous, open, or polyamorous couple. Results demonstrated that there was a significant difference between the groups exposed to the various relationship configurations in terms of the perceptions of the hypothetical couples’ relationship satisfaction, F(2,318) = 3.12, p = .045. Specifically, the monogamous couple was rated as having higher relationship satisfaction than the open couple. Such a study has implications for garnering a better understanding of the preconceived notions we hold about the lifestyles of others. As this area warrants further investigation, exploration is still ongoing.
