Science of Love: Do Opposites Attract, or Are We Drawn to Likeness?

wikitree Views  

Results of a study involving more than 8,000 couples
Similarity between male and female partners: 82% to 89%

Regarding attraction between the sexes, do we tend to be drawn to someone different from ourselves or someone similar?

On the 6th, according to a report from The Guardian on the 4th (local time), Comedy.com reported that, based on a study of over 8,000 couples, the latter was stronger.

This information is based on a paper published in “Nature Human Behaviour” by University of Colorado Boulder researchers.

The researchers analyzed how 22 characteristics among couples were shared in 199 papers related to male-female partnerships from 1903 to August 2022. Then, they expanded their analysis to 133 characteristics, including the original 22, for 79,074 heterosexual couples registered in the UK Biobank Project. Same-sex couples were excluded from the study due to differences in behavior and characteristics.

As a result, both studies found that the similarity between male and female partners ranged from 82% to 89%, with only about 3% classified as significantly dissimilar.

Most couples showed high similarity in various characteristics, including political and religious beliefs, educational levels, and specific IQ scales. It was observed that people who smoked a lot, drank heavily, or abstained from alcohol tended to have the same habits in their partnerships.

However, factors like height, weight, health issues, and personality traits vary from couple to couple.

For example, extroverted individuals were less likely to partner with introverted individuals compared to other extroverted individuals, as explained by the media.

Concerning this, researcher Horvitz concluded, “The principle of ‘birds of a feather flock together’ also applies to matchmaking,” and added, “Even in situations where we feel we have a choice in our relationships, there may be underlying mechanisms at work that we are not fully aware of.”
