A previous experiment showed that there was a strong correlation between conservatism/liberalism and brain activity, linked to an error response ( = 0.59, < 0.001) in the USA political environment. We re-ran the experiment on a larger and age-homogeneous group ( = 100, 50 females and 50 males, aged 20-26 years) in the Czech Republic; a European country with a different sociocultural environment and history. We did not find a relationship between the brain activity connected to conflict monitoring and self-reported conservatism/liberalism orientation (ρ = -0.11, = 0.297) or conservatism/liberalism validated for the USA agenda (ρ = -0.01, = 0.910). Instead of replicating the previous study, we decided to test the hypothesis under a different socio-cultural context. Our results support a view of self-reported or validated, conservative or liberal attitudes as a complex behavioral pattern. Such a behavioral pattern cannot be determined with statistical significance, using a simple Go-NoGo detection task, without accounting for confounding factors such as age and socio-cultural conditions. Sufficiently powered studies are warranted to evaluate this neuro-political controversy.
先前的一项实验表明，在美国的政治环境中，保守主义/自由主义与大脑活动之间存在很强的相关性，这种相关性与错误反应相关（= 0.59，< 0.001）。我们在捷克共和国一个更大且年龄分布均匀的群体（= 100人，50名女性和50名男性，年龄在20至26岁之间）中重新进行了该实验；捷克是一个具有不同社会文化环境和历史的欧洲国家。我们没有发现与冲突监测相关的大脑活动与自我报告的保守主义/自由主义倾向（ρ = -0.11，= 0.297）或针对美国议程验证的保守主义/自由主义之间存在关联（ρ = -0.01，= 0.910）。我们没有重复先前的研究，而是决定在不同的社会文化背景下检验该假设。我们的结果支持将自我报告的或经验证的、保守或自由的态度视为一种复杂行为模式的观点。在不考虑年龄和社会文化条件等混杂因素的情况下，使用简单的Go-NoGo检测任务无法以统计学显著性确定这样一种行为模式。有必要进行有足够效力的研究来评估这一神经政治争议。
