A little while ago, I got into a debate with Vipul Naik over the link between social conservatism and open borders. My hypothesis was that social conservatives would oppose open borders because they are defending in-group privilege. Also, being socially conservative correlates with Republican party identification, which correlates with negative views of immigrants. In contrast, Vipul thought that the opposite might be true. Social conservative ideas (e.g., anti-abortion) do not logically entail anti-immigrant views. Immigration attitudes might be decoupled from social attitudes.
Here is what I found out when I used the General Social Survey to explore this issue. First, you have to identify an immigration question. The GSS has a few. The most general is “527. Do you think the number of immigrants from foreign countries who are permitted to come to the United States to live should be increased a lot, increased a little, left the same as it is now, decreased a little, or decreased a lot?” 1 – increased a lot. 5 – Decreased a lot. Roughly speaking, 8% increase, 37% stay the same, 54% decrease immigration.
Ok, let’s crank through some measures of social conservatism:
* Ideology: “66 A. We hear a lot of talk these days about liberals and conservatives. I’m going to show you a seven-point scale on which the political views that people might hold are arranged from extremely liberal–point 1–to extremely conservative– point 7. Where would you place yourself on this scale?” Correlation? .094 – p-value <.001. n=2598.
* Abortion attitudes: “251. Do you think abortions should be legal under any circumstances, legal only under certain circumstances, or never legal under any circumstance?” 1 – Always. 3 – Never. Correlation? .016, not significant. N=1497.
* Gay Rights: “219. What about sexual relations between two adults of the same sex–do you think it is always wrong, almost always wrong, wrong only sometimes, or not wrong at all?” 1- Always wrong, 4 – not wrong at all. Correlation? -.138, p <.001. N=1702.
* Affirmative action for blacks/women: “153/552. A. Some people say that because of past discrimination, blacks/women should be given preference in hiring and promotion. Others say that such preference in hiring and promotion of blacks is wrong because it discriminates against whites. What about your opinion — are you for or against preferential hiring and promotion of blacks?” 1. strong support to 4 strong oppose. Correlations? .198/.091 . p<.001/p =.07. N= 383 (each).
* Biblical literalism: “120A. Which of these statements comes closest to describing your feelings about the Bible? a. The Bible is the actual word of God and is to be taken literally, word for word. b. The Bible is the inspired word of God but not everything in it should be taken literally, word for word. c. The Bible is an ancient book of fables, legends, history, and moral precepts recorded by men.” 1 – word of God, 3 – book of fables. Correlation? .071, p=.16. N=383.
Bottom line: Anti-immigration views are always positively correlated with what we’d consider indicators of being socially conservative. In some cases, the correlation is strong, in other cases not significant. However, there are no cases where being conservative is correlated with having pro-immigration views.
