Do you Display this Common Behavioural Bias when you Kiss?

Psychological research has suggested that humans tend to engage in a particular behaviour when they kiss. Grab your loved one now and see if you do too.

Have you ever considered how you kiss your loved one? Well, before you read this column, I’d like you to do it, right now – visualise the last time you kissed someone on the lips.

Done that? OK let’s continue…

The reason I asked was to allow you to see if you conform to the fascinating behavioural insight that psychologists have uncovered related to how you tilted your head. It added to well-known research that suggests infants have a bias to tilt their head to the right and suggested that when we adults kiss, we are likely to do the same.

Interestingly this behaviour seems to cross cultures too as it was also observed in parts of the world where kissing in public is forbidden and suggests that even when behind closed doors people did the same thing.

So, when you have the opportunity, ask your partner to give you a kiss and see whether, in real life, he or she backs up this research.

Enjoy it!

See you next week, until then take care,
