People often assume that procrastination is a choice and that the personality trait — which sees people delay necessary tasks — is a sign of laziness. 人们通常认为拖延症是一种选择，而且这种让人推迟必要工作的人格特点是懒惰的表现。 However, new research suggests that genes may play a role. 但有新研究表明这是受基因影响的。 Previous research has associated both biological and psychological factors with procrastination. 此前的研究分析了导致拖延症的生理和心理因素。 The results of a 2018 study showed that people with a tendency to procrastinate had a bigger amygdala — the section of the brain that processes emotions. 2018年一项研究的结果显示有拖延症倾向的人杏仁核更大，杏仁核是大脑中负责处理情绪的部分。 The same research team has now studied whether there is an association between the trait and genetics. 该研究团队现在研究了这个性格特点和遗传学之间的联系。 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. 此前发表在《Psychological Science》杂志上的一项研究研究了同卵双胞胎和异卵双胞胎，其作者得出的结论是46%的拖延倾向都是由基因决定的。 |
