美国的研究团队调查了180个年轻的男性与女性，经过详细了解了他们以往的感情史与
爱情观之后，对他们做名为 DRD4的基因检测，据悉，这种基因能够影响大脑中多巴胺
的含量。研究发现，大约25%的人拥有“偷情基因”，而拥有这种基因的人更容易对伴
侣做出不忠的行为、发生一夜情的几率比普通人要高出两倍。
Last month, scientists found that the same strain of the DRD4 gene can
also make people have more liberal views. Because the genetic variant drives
people to seek out ‘novelty’, it can also make people more likely to seek
out less conventional political views, the U.S. study found。
科学家还发现，“偷情基因”并非只具有负面作用，它还具有一些正面影响呢。据
调查，具有这种基因的人更能接受新奇的事物，包容性更强。如果对于政治家来说，具
有这种基因的政治家往往属于革新派、改革派类别。

这不就是德州大叔上次那个贴子的科学论据吗

1996年的冷饭再炒一遍？
from wiki
The dopamine receptor D4 is a G protein-coupled receptor encoded by the DRD4
gene.[1] As with other dopamine receptor subtypes, the D4 receptor is
activated by the neurotransmitter dopamine. It is linked to many
neurological and psychiatric conditions including schizophrenia, Parkinsons
disease, bipolar disorder, addictive behaviors, and eating disorders such as
anorexia nervosa, bulimia nervosa and binge eating.
Novelty seeking
Despite early findings of an association between the DRD4 48bp VNTR and
novelty seeking (a characteristic of exploratory and excitable people),[12][
13] a 2008 meta-analysis compared 36 published studies of novelty seeking
and the polymorphism and found no effect. The meta-analysis of 11 studies
did find that another polymorphism in the gene, the -521C/T, showed an
association with novelty seeking.[14] In any case, novelty-seeking behavior
is probably mediated by several genes, and the variance attributable to DRD4
by itself is not particularly large.

不是专业的，不过“偷情”这种大脑高级行为被单一基因控制而不是多个基因共同作用
的结果，这个结论确实需要比较强的实验让人接受
