Previous research has associated both biological and psychological factors with procrastination. The results of a 2018 studyshowed that people with a tendency to procrastinate had a bigger amygdala — the section of the brain that processes emotions.

The same research team has now studied whether there is an association between the trait and genetics.

After examining identical and fraternal twins, the authors of a previous study, which featured in Psychological Science, concluded that 46% of the tendency to procrastinate might be down to genes. However, researchers still do not know the specific genetic difference that could result in this trait.

Dr. Erhan Genç, from Ruhr-Universität Bochum in Germany, believes that he may now have the answer. But, there is a catch: it only relates to women.
