I believe this point on social theory was discussed during Mahendra Prasad talk at 2019’s EA Global London (I didn’t attend it but Mahendra sent me the slides). This hypothesis that deliberation could shift individual preferences toward single-peakedness appears to be lent support in deliberative poll experiments (e.g. Farrar et al. 2010). I did not see a neat way to explain this point in the essay, but have included a small mention of it instead. Thanks for offering this useful summary!
