A new study from an international team of psychologists and neuroscientists suggest that humans are hardwired to favour leaning to the right while kissing romantic partners, which may have wider implications for neuroscience and cognitive sciences. Building on previous work from Western countries, a new academic paper just published in the journal Scientific Reports , is the first to investigate an inherent bias for turning the head to one side while people kiss in a non-Western context, in Bangladesh, where romantic kissing is not typically observed in public. For the study, the researchers from our Department of Psychology along with colleagues at the universities of Bath Spa and Dhaka Bangladesh , invited 48 married couples to kiss privately in their own homes, and after kissing they were asked to go to different rooms, open an envelope and then report on various aspects of the kiss independently of each partner. Their results highlight a bias to turn heads to the right when kissing for both the initiator and the recipient of the kiss, and also that men were about 15 times more likely than women to initiate kissing. Over two-thirds of the kiss initiators and kiss recipients turned their heads to the right.

People are hard-wired to tilt their heads to the right when kissing a romantic partner, an international study has found. Building on work from western countries, the universities of Dhaka, Bath and Bath Spa set out to investigate kissing behaviours, including a bias for turning the head to one side. The research, published in the journal Scientific Reports, studied 48 married couples in Bangladesh, where kissing is not generally observed in public. The couples were asked to kiss privately in their homes and independently report on different aspects of the kiss. It found that men were about 15 times more likely to initiate kissing than women, and that both partners preferred to lean their heads to the right.
