Much debate has surrounded the relative contribution of genetic inheritance and environment to human intelligence. In addition, fetal hormones may influence brain development and affect the qualitative nature of intellectual skills. Geschwind and Behan, Proc. Natn. Acad. Sci. 79, 5097-5100, 1982, have suggested that such hormones may also influence both the development of handedness and the development of the immune system. Members of the faculty of the University of Oxford participated in a survey investigating field of study; handedness and immune disorders. Even amongst right-handers, mathematical academics are significantly more susceptible to rare immune disorders and four times likely as verbal academics, to have suffered from a language related problem in childhood. In contrast to previous suggestions, the incidence of left-handedness is not found to be high amongst pure mathematicians but is significantly higher amongst scientists using mathematical applications.
围绕遗传和环境对人类智力的相对贡献存在诸多争论。此外，胎儿激素可能会影响大脑发育并影响智力技能的质性本质。格施温德（Geschwind）和贝汉（Behan）在《美国国家科学院院刊》79卷，第5097 - 5100页，1982年提出，此类激素可能还会影响用手习惯的发展以及免疫系统的发育。牛津大学的教员参与了一项调查，该调查涉及研究领域、用手习惯和免疫紊乱。即使在右利手人群中，数学领域的学者患罕见免疫紊乱的易感性也显著更高，且患童年期与语言相关问题的可能性是文科领域学者的四倍。与之前的观点相反，在纯数学家当中，左利手的发生率并未发现很高，但在使用数学应用的科学家中，左利手的发生率显著更高。
