That is not an argument that intuition or emotion, i.e., subjectivity or personal bias, is always bad or needs to be completely removed from politics. That is impossible. Human memory (facts), emotion and decision-making are processed together in a brain structure (the amygdalae). It is not possible to fully separate objective fact and logic from subjective ideology, faith or values. Basic human biology precludes that kind of operation - people can strive be close to objective and rational, but they can never be perfect.
The two-party political system fully understands this aspect of human biology. It ruthlessly plays on the biology personal ideology as a means to distract, deceive, misinform and polarize the American people into irrational status quo support. Meanwhile, the two-party system quietly serves its own ends, primarily sustained political power with minimal meaningful opposition, with little or no regard for the public interest as Dissident Politics argued before.
Being rational is affected by human physiology, e.g., blood sugar levels, physical fatigue and being sleepy. Perceptions of reality and logic are subject to an astonishing array of unconscious biases, e.g., priming effects, framing effects, halo effects, anchoring effects, confirmation bias and the powerful but easy to invoke “what you see is all there is” (WYSIATI) bias.
The same is true for politicians and partisan pundits - they need to when personal bias distorts laws facts and logic. Unfortunately, they rarely know bias because seeing it is uncomfortable and requires moral courage.
