People's knowledge of and attitudes toward abortion laws before and after the decision.

Although media response to the decision was widespread in the United States, the extent to which people were aware of the Mississippi law leading to the decision, the case, is unclear, as are the resulting effects of the decision on legal abortion. As such, we examined people's awareness of abortion legality prior to and after the decision announcement, as well as the potential implications associated with the decision (i.e. overturning of ). We also examined people's attitudes toward abortion legality, specifically focusing on 15 weeks' gestation to correspond with the Mississippi law that led to . Data were collected across two studies at different times. In Study 1, a 15-minute survey was administered to IPSOS' KnowledgePanel (= 1014) prior to the decision announcement. A shorter version of that survey was administered to a second sample using NORC's AmeriSpeak Omnibus panel (= 1002). Nearly half of that sample (42.2%) completed the survey prior to the decision announcement. People were generally unaware of the Mississippi law, the case, and implications associated with the decision (e.g. overturning ). People generally endorsed abortion being legal at 15 weeks or later, but this varied by circumstance. We did not find meaningful effects of the decision announcement on people's knowledge and attitudes. Our findings suggest that the intense response to the decision from the media and people involved in the abortion movement may not represent the general public's reaction.
