ABSTRACT In many countries, a radical political divide brings several socially relevant decisions to a standstill.Could cognitive, affective and social Televisions (CAS) neuroscience help better understand these questions? The present article reviews the moral-psychological and neuroevolutionary basis of the political partisanship divide.A non-systematic literature review and a conceptual analysis were conducted.
Three main points are identified and discussed: 1) Political partisan behavior rests upon deep moral emotions.It is automatically processed and impervious to contradiction.The moral motifs characterizing political partisanship are epigenetically set across different cultures; 2) Political partisanship is linked to personality traits, whose neural foundations are associated with moral feelings and judgement; 3) Self-deception is a major characteristic of political partisanship that probably evolved as an evolutionary adaptive strategy to deal with the intragroup-extragroup Nail care kit dynamics of human evolution.
CAS neuroscience evidence may not resolve the political divide, but can contribute to a better understanding of its biological foundations.
