Do opposites attract? The fact and the fiction behind the myth
From Billy Joel crooning about an uptown girl wanting a downtown man, Pretty Woman, the star-crossed lovers Romeo and Juliet, Beauty and the Beast, the Cinderella fairytale, and many more, we have been told this story of opposite attraction across multiple mediums as varying as Shakespearean literature to Disney movies.
The irresistibly romantic tale of unlikely love beating the odds has become a beloved storyline and has turned into a widely held belief which explains this social and natural phenomenon. But that is also how we describe a myth1. The problem with a myth is that the facts are often unsubstantiated, based rather on populous opinion, easy to believe but lacking the evidence to validate it.
Magnetic appeal: do opposites really attract in relationships?
To get to the bottom of the mystery of do opposites really attract, we brought in some heavy-hitting experts. Speaking to EliteSingles, Dr. David Stillwell, Deputy Director of Psychometrics at the Cambridge Judge Business School at the University of Cambridge and Dr. Angela Bahns, Professor of Psychology at Wellesley College, unpack their insight from leading research studies in psychology and attraction in today’s world of dating and relationships.
Dr. Stillwell, co-author of the study Birds of a feather do flock together: behavior-based personality assessment method reveals personality similarity among couples and friends, investigated personality similarities, using behavior and language in romantic partners and friends on social media. He explains that up to this point there was evidence for similarity in partners across age, education and socio-economic level, intelligence and values; however, similarity had not yet been established in personality traits2.
Using the Big Five Model of Personality, the study tracked the digital activities of 295 320 participants on Facebook to measure their similarities and differences3. When answering our question do opposites really attract, looking at personality is a fundamental psychological construct in appeal and relationships.
The Big Five Model of Personality is the leading personality model in academic research, measuring traits across five dimensions: openness to experience, conscientiousness, extroversion, agreeableness, and neuroticism. The unique contribution of this study is that previous research relied on peer and self-reported questionnaires to measure and compare personality traits, whereas, in this study, the individuals’ behavior was analyzed, removing the ‘reference group effect’ of comparing oneself to other individuals in your environment. By circumventing this limitation, they were able to demonstrate a new and more accurate result.
What the study conclusively found is that opposites do not actually attract, rather that there was a significant similarity in personality between friends and romantic partners3, dispelling the myth that opposites attract with scientific research taken directly from today’s online social environment. Dr. Stillwell told EliteSingles, “Our unique contribution was to show that when you measure personality based on behavior (what people talk about online, or what they 'like' on Facebook), that personality is similar after all”2, concluding that birds of a feather do indeed flock together.
Taking a look at the question of opposite attraction in relationships from a different angle we also chatted to Dr. Bahns on the matter of do opposites really attract or not. She is a researcher and co-author in the study Similarity in relationships as a niche construction: Choice, stability, and influence within dyads in a free choice environment, which investigated similarity in interacting pairs across a range of factors, from values to recreational activity. The research showed that the pairs in the study largely shared similar views and confirmed that like-minded individuals are attracted to each other4. She explains “similarity-seeking in relationships is goal-driven, and for many people, choosing on the basis of similarity satisfies their goals of comfort, familiarity, and predictability”5.
Summing up the expert opinion and research findings, the legend of opposite attraction has been discredited. In reality, behavioral interactions and personality traits in attraction are not driven, like the positive and negative charges of a magnet by attracting the opposite, but rather in relationships differences can repel, making true the adage like attracts like.
