Abstract

Introduction With the recent changes to the composition of the Supreme Court in the USA, speculation that Roe v. Wade may be overturned abounds. Research assessing people’s knowledge and sentiment toward Roe v. Wade is limited. As such, we assessed the relationship between knowledge and sentiment regarding Roe v. Wade and whether the relationship is moderated by political affiliation and abortion identity (e.g., “pro-life,” “pro-choice”).

Method In 2018, after Justice Brett Kavanaugh was nominated to the Supreme Court, we distributed an online survey to a quota-based sample of English- and Spanish-speaking adults in the USA.

Results Roe v. Wade knowledge was significantly related to sentiment; higher knowledge was generally associated with greater support for upholding Roe v. Wade. However, both political affiliation and abortion identity moderated this relationship. Specifically, higher baseline knowledge was associated with lower sentiment scores among those identifying as Republican and “pro-life.” Those who identified as neither or both “pro-life” and “pro-choice” and Independents responded similarly to those who identified as pro-choice and Democrats, respectively.

Conclusion Roe v. Wade knowledge is associated with sentiment; this relationship is moderated by political affiliation and abortion identity. People in subgroups without a clear stance on abortion (e.g., Independents; people who identify as neither or both “pro-life” and “pro-choice”) seem to hold sentiments similar to those more supportive of abortion (e.g., Democrats, “pro-choice”).

Policy Implications In addition to other data, policymakers should consult comprehensive assessments of constituents’ attitudes toward Roe v. Wade when making decisions about abortion and reproductive health issues.
