This explains a lot about what is going on in here.
Hugo Mercier and Dan Sperber are two evolutionary psychologists who proposed that humans have evolved to prioritize winning arguments over seeking truth. Their "argumentative theory of reasoning," outlined in works like The Enigma of Reason (2017 French edition), posits that human reasoning developed primarily for social persuasion and debate, not solitary truth-finding. This explains why reasoning often falters individually but improves in group discussions, as evolution favored skills that helped convince others in collaborative ancestral environments. Their theory has gained traction in discussions of why people cling to flawed beliefs during arguments.
