尽管有大量关于人格特质与血型之间联系的研究，但在文献中找不到关于道德与血 型之间联系的研究。
我们进行了研究，根据Haidt（Science 316：998-1002，2007）的说法，血型是否对道德基础在个人中可观察到的程度有任何影响。
我们的研究集中在240名成年男性和女性受试者，平均年龄为43.47岁;每组基于ABO血型系统，总共由60名受试者组成。
根据获得的数据，我们可以得出结论，伤害和纯洁的道德基础与血型之间存在联系。

In order to find possible correlations between moral foundations and blood types, we performed analysis of variance (ANOVAFootnote5) on our data.
ANOVA (Table 2) shows that our respondents’ scores on the foundations of Harm (F=4.300 p=0.006, η 2=0.05) and Purity (F=4.653 p=0.004, η 2=0.06) significantly differ statistically by the various blood types.
According to Cohen [26], we can say that all our effect sizes are about medium.
Post hoc analysisFootnote6 (see Table 3) has shown the following: The Harm dimension was significantly more pronounced within B type subjects than within O and AB blood types.
A blood type subjects have a more pronounced Purity dimension than AB blood type subjects. Also, B blood type subjects scored significantly higher on this dimension than AB types.
