Why the #%!@ do we Swear? The Neuroscience Behind Sex Differences in Expletive Language

Swear words in everyday life appear a somewhat concerning, though almost essential occurrence. As most people can attest to, these choice expletives serve a variety of functions, from expressing anger, reacting to injury, promoting aggressiveness, or simply emphasizing a point. Taboo language is a widely and passionately discussed topic, often in terms of censorship and minimizing its negative impact. However, conversations in the scientific community focus on the evolutionary and biological development of swearing, and interestingly on its positive impact. A blog post titled "The Science of Swearing" suggests that swear words can achieve a number of desirable outcomes, such as joking or storytelling, stress management, group cohesion, or as a replacement for potential physical aggression.

With this multi-faceted approach to swear words, an interesting question remains: how has swearing become associated with differences between males and females. Sex differences in swear words have been reported across cultures and over time. In general, males use more frequent and more forceful obscene language than females. A review conducted by Ginsburg et al. (2003) gives an overview of past research conducted on sex differences in vulgar language, in terms of types of usage, attributions and perceptions, and why these sex differences occur.[1] They explain that there are several theories accounting for why males may swear more than females. Evolutionarily, profanity may have originally been used during male combat as a means to shock and awe opponents. Additionally, it may contribute to destructive aggressive and sexual urges in males. Comparatively, from a socialization perspective, females may be taught to use more polite and less forceful words, thus swearing less.

Studies on neurolinguistic perspectives on swearing have also contributed to knowledge of sex differences. A study by Lancker and Cummings (1999) found that use of expletives is increased in adults with Gilles de la Tourette syndrome (GTS), a condition estimated to have a 9:1 male to female sex ratio.[2] Further studies of the physiological impact of swearing on the brain have revealed some important insights. A different blog with the same title "The Science of Swearing" describes that our brains are hard-wired to react to taboo words. The amygdala, an emotion-processing center in the brain is activated in response to reading a swear word.  A potential explanation for this might be that swearing can communicate strong emotions better than non-taboo words. A sociocultural sex difference explanation relating to this could be that males are encouraged to swear to release feelings of anger and aggression while females are taught to suppress these emotions.

In addition, a fascinating role of swearing can actually be to lessen the effects of physical pain. A study conducted by Richard Stephens and Claudia Umland[3] in 2011 asked participants to stick their hand into freezing cold water and repeat either a favorite expletive or a neutral word. Perhaps unsurprisingly for anyone who’s ever smashed their toe into a piece of furniture, swearing increased pain tolerance and heart rate compared to not swearing. This study also examined sex differences between subjects. As shown in the figure below, in comparison between swearing and not swearing, males showed slightly greater differences in pain tolerance and heart rate increase compared to females.


Taken together, these findings on sex differences in swear words present several interesting implications. Since the literature on the neurological differences between men and women in swearing is relatively sparse, speculation is far more prevalent than definitive conclusions at this time. A clear finding is that males appear to swear more than females, as evidenced by attributions and stereotypes in society. However the primary inconclusive debate concerns whether this difference is due to biological factors, sociocultural learning, or a combination of the two. One biological possibility, considering the clear relationship between swearing and aggression, and higher levels of aggression in males, is that prenatal exposure to androgens and higher levels of testosterone are the mediating factors that contribute to both increased swearing and aggression in males. As Ginsburg suggests, the cultural universality of greater male expletive language suggests some sort of biological predisposition. Of course, cultural norms and rules certainly contribute to exaggerate these differences by inflicting harsher societal penalties on females for swearing than males.

The bottom line of the science of swearing appears to be that regardless of male or female, taboo words can actually benefit the speaker (not suggesting that a child uses this argument in front of their furious parent after letting an f-bomb fly) but the study of swear words undoubtedly reveals an interesting and nuanced side of human nature.

  1. Could it even be possible that since society identifies certain words as expletive, men are just more comfortable swearing, because it is more socially acceptable? So that because of the society's expectations of gender-specific language, men are more socially encouraged to use certain words.
