A study published by scientists at Oregon State University and the University of California has revealed that a single variation in our genetic make-up can influence how we react to stress and empathize with others, reported The LA Times.

The chemical they looked at was oxytocin – found in the OXTR gene and known by scientists as the chemical of bonding and nurture. Having a calming effect, it reacts to warm human interaction, falling in love, and skyrockets after sex.

To determine how levels of oxytocin in our body affect behaviour, 192 college students were put to the test. Measuring their ability to read other’s emotions through looking at their facial expressions, the research revealed that students who had inherited the OXTR gene from both parents had an increased ability to empathize. 

While it appears to be one more victory for nature over nurture, genetic inheritance is by no means the sole determinant of our personalities. With our environment and experiences playing an important role in our behavioural patterns, don’t blame the ‘rents just yet!
