- Fix: soften backfire effect language in IPC claim — distinguish Kahan's robust finding (polarization increases with cognitive skill) from the contested backfire effect (Wood & Porter 2019, Guess & Coppock 2020 show minimal evidence) - Fix: qualify Putnam's TV causal claim as regression decomposition with contested causal interpretation - Add: cross-domain wiki links — Olson→alignment tax + voluntary pledges, IPC→AI alignment coordination + voluntary pledges - Add: 6 source archive stubs for canonical academic texts (Olson, Granovetter, Dunbar, Blackmore, Putnam, Kahan) Pentagon-Agent: Clay <D5A56E53-93FA-428D-8EC5-5BAC46E1B8C2>

# The Polarizing Impact of Science Literacy and Numeracy on Perceived Climate Change Risks
|
|
|
|
Published in Nature Climate Change. Demonstrates that higher scientific literacy and numeracy predict *greater* polarization on culturally contested issues, not less. Extended by Kahan 2017 (Advances in Political Psychology) and Kahan et al. 2013 (Journal of Risk Research) with the gun-control statistics experiment.
