The two present nomothetic studies focused on the period from 1996 to 2012 to determine relations between handedness and political orientation using the 48 contiguous American states as analytical units. The estimated percentage of left-handers in each state operationally defined handedness. A composite measure of Conservative-Republican preference was created from CBS/New York Times/Gallup polls of state resident conservatism and the percent in each state voting Republican in each presidential election from 1996 to 2012. Study 1 showed that state levels of left-handedness correlated to an extremely high degree with Conservative-Republican preference (r = −.80). As well, with common demographic differences between states reflected in socioeconomic status, White population percent, and urban population percent controlled through multiple regression, handedness still accounted for an additional 37.2% of the variance in Conservative-Republican preference. Study 2 found that each of the Big Five personality variables correlated significantly with handedness and with Conservative-Republican preference, but in the opposite direction. Furthermore, Study 2 demonstrated quite surprisingly that all Big Five personality relations to Conservative-Republican preference were eliminated when handedness was controlled in multiple regression equations. For all regression equations, the global Moran’s I test specifically developed for detecting residual spatial autocorrelation indicated no significant spatial autocorrelation.

当前的两个非自然运动研究集中在1996年至2012年这一时期，以美国48个连续州作为分析单位来确定惯性与政治取向之间的关系。在每个州中，左撇子的估计百分比在操作上定义为惯用惯性。根据CBS /《纽约时报》 /盖洛普（Gallup）对州居民保守主义的调查以及1996年至2012年每次总统选举中各州投票的共和党人的百分比，得出了保守党和共和党人偏好的综合量度。研究1显示，州的左撇子水平与保守党和共和党的偏爱高度相关（r = -.80）。同样，由于各州之间的共同人口差异反映在社会经济地位，白人人口百分比和城市人口百分比通过多元回归控制的情况下，在保守党和共和党人的偏爱中，手感仍然占差异的37.2％。研究2发现，五个大人格变量中的每个变量都与惯用性和保守共和党偏爱显着相关，但方向相反。此外，研究2出乎意料地证明，在多重回归方程式中控制手性时，所有与保守党-共和党人偏爱的大五人格关系都被消除了。对于所有回归方程，全局Moran's I 专为检测残留空间自相关而开发的测试表明没有明显的空间自相关。
