Not everyone chosen by the lottery actually served, creating variation in both draft exposure and service status. \\nInterviews were conducted in wave 4 (prior to July 1, 1970 lottery) and wave 5 (spring 1974), allowing examination of attitude changes over time. Each row contains an individual's political preferences in a given wave. Focus on waves 4 and 5. \\nThe direct effect captures how lottery assignment affected political preferences independent of military service\u2014through heightened political awareness, life planning changes, or social identity shifts. The indirect effect operates through actual military service experience.\\n\\nVariables in the dataset:\\n\\nwave: phase when the political preferences were measured\\ntreatment1: whether the individual actually served in military\\nceiling: 1 if the individual was chosen by the draft lottery, 0 otherwise\\nid: person identifier (used for the estimating standard errors via bootstrap)\\nrepu: whether the individual describes themselves as a mild republican\\nsrepu: whether the individual describes themselves as a strong republican\\ndemo: whether the individual describes themselves as a democrat\\nsdemo: whether the individual describes themselves as a strong democrat\\npolalient: political alienation, how skeptical the individual is about the government\\nVietnam: how skeptical the individual is about the Vietnam war\\nERindex: preferences for civil rights interventions\",\n \"columns\": {\n  \"id\": \"float64\",\n  \"treatment1\": \"float64\",\n  \"V3\": \"float64\",\n  \"V4\": \"float64\",\n  \"yob\": \"float64\",\n  \"draftnr\": \"int64\",\n  \"ceiling\": \"float64\",\n  \"srepu\": \"float64\",\n  \"sdemo\": \"float64\",\n  \"repu\": \"float64\",\n  \"demo\": \"float64\",\n  \"polalient\": \"float64\",\n  \"Vietnam\": \"float64\",\n  \"ERindex\": \"float64\",\n  \"wave\": \"float64\",\n  \"mc_student\": \"float64\",\n  \"mc_avail\": \"float64\",\n  \"mc_notcl\": \"float64\",\n  \"mc_other\": \"float64\",\n  \"milknow\": \"float64\",\n  \"iqtest\": \"float64\",\n  \"spiq\": \"float64\",\n  \"collplan\": \"float64\"\n }\n}"}
