Peace and global security are human endeavors, and thus their attainment depends as much on psychology as it does on governance and technology. In this paper I outline 3 ways our evolved psychology is an obstacle to achieving international cooperation and peace. First, humans show strong evidence of adaptations for cooperation within groups, but equally clear evidence that this cooperative nature does not extend to members of other groups. Second, humans evolved to have a relative sense of fairness, and thus will often reject even mutually beneficial agreements if they benefit others more than themselves. Third, humans evolved to be self-deceptive and hypocritical, believing in the unique righteousness and inevitable victory of their own cause, which tends to exacerbate conflict. Nevertheless, these obstacles are not insurmountable and an awareness of them can help in the development of strategies to increase the chances of lasting peace and security.

和平与全球安全是人类的努力，因此它们的实现在很大程度上取决于心理，也取决于治理和技术。在本文中，我概述了我们进化的心理是实现国际合作与和平的障碍的三种方式。首先，人类表现出对群体内合作适应的有力证据，但同样明确的证据表明，这种合作性质不会扩展到其他群体的成员。其次，人类进化为具有相对公平感，因此如果他们对他人的好处多于对自己的好处，他们往往会拒绝甚至互惠互利的协议。第三，人类进化为自欺欺人、虚伪，相信自己事业的独特正义和必然胜利，这往往会加剧冲突。尽管如此，
