Drivers of cars that are newer (and hence safer), bigger, and with better high-speed characteristics, prefer higher speed limits, as do those who believe they drive better than average, whereas elderly people prefer lower limits. Furthermore, people report that they themselves vote more sociotropically than they believe others to vote, on average. Self-serving biases are proposed as a bridge between subjectively perceived expressive and sociotropic voting behavior, versus objectively self-interested voting behavior.17 pages164729 bytesapplication/pdfenSpeed limits; self-interested voting; expressive voting; sociotropic voting; selfserving biasadaptive political preferencesReportEconomics
