Racial resentment was a substantial "cause" of environmental policy preferences in 1986

Racial attitudes have substantially correlated with environmental policy preferences net of partisanship and ideology, such as here, here, and here. These results were from data collected in 2012 or later, so, to address the concern that this association is due to "spillover" of anti-Obama attitudes into non-racial policy areas, I checked whether the traditional four-item measure of racial resentment substantially correlated with environmental policy preferences net of partisanship and ideology in ANES data from 1986, which I think is the first time these items appeared together on an ANES survey.

I limited the sample to non-Hispanic Whites and controlled for participant gender, education, age, family income, partisanship, and ideology, and the race of the interviewer. The outcome variable concerns federal spending on improving and protecting the environment, which I coded so that 1 was "increased" and 0 was "same" or "decreased", with Don't Knows and Not Ascertaineds coded as missing; only 4 percent of respondents had indicated "decreased".

Other model variables at their means, the predicted probability of a reported preference for increased federal spending on improving and protecting the environment was 65% [54%, 76%] at the lowest level of racial resentment, but fell to 39% [31%, 47%] at the highest level of racial resentment. That's a substantial 26 percentage-point drop "caused" by racial attitudes, for anyone who thinks that such a research design permits causal inference.

NOTES:

1. Kinder and Sanders 1996 used racial resentment to predict non-racial attitudes (pp. 121-124), but, based on reading that section, I don't think KS96 predicted this environmental policy preference variable.

4. The post title is about 1986, but some ANES 1986 interviews were conducted in Jan/Feb 1987. The key result still holds if the sample is limited to cases with an "86" year for the "Date of Interview" variable, with respective predicted probabilities of 67% and 37% (p=0.002 for racial resentment). About 4 or so dates appear to be incorrect, such as "01-04-86", "12-23-87", and "11-18-99". Code:
