Is motivated partisan cognition bipartisan?The extent to which each side exhibits motivated partisan (or biased) cognition is a focus of ongoing debate. Some scholars argue for symmetry (SM). For example, a recent meta-analysis demonstrates equivalent levels of motivated partisan cognition across 51 experiments investigating the tenden cy to evaluate otherwise identical in-formation more favorably when it supports versus challenges one’s political beliefs or allegiances (14). In an illu strative experiment, liberals and conservatives viewed a film clip of a political demonstration in which protestors clashed with police. Despite view-ing the identical clip, liberals rated the protesters as more violent when they believed it was an anti-abortion protest (a conservative cause) rather than a gay-rights protest (a liberal cause), whereas conservatives exhibited the opposite pattern (SM). Other scholars argue for asymmetry. For example, some evidence suggests that, relative to Democrats, Republicans have a higher need for order and greater trust in their gut-level intuitions. Such tendencies appear to motivate them to favor explana-tions that are straightforward and intuitive rather than complex and abstract, even when the latter types of explanation might be more accurate (15) (SM). Such findings are representative of the existing evidence, but conclusions remain tentative.
This is classic material to add to that which i dug up in 2016 about non-attachment to views.
