Psychological Science 19.3 (2008): 249-254. For files from the original study, see osf.io/ug9fx **Target of replication:** This replication sought to reproduce two of the original findings. To be successful, both must replicate: 1) On the explicit measure, a significant difference in person preference when rating the immediate-original pair versus the immediate-new pair (i.e., at least a partial lack of attitude generalization) AND 2) On the implicit measure, no significant difference in person preference when rating the immediate-original pair versus the immediate-new pair (i.e., immediate generalization of attitudes). As the RPP can only use one effect in the meta-analysis, the implicit measure was chosen to be included as the "key effect" to be reported. Both the implicit and explicit measures are needed to fully embody the important points of the original study, but as the original explicit measure's prediction and result in the original study were completely in line with naive expectations, the implicit measure—with its slightly more unexpected results—was chosen to be included in the meta analysis. **Note:** The protocol available here replaces the one that was pre-registered prior to data collection (visible in on the registrations page). Due to unexpected time constraints, it was not possible to test the results we originally intended to replicate. We chose a different set of target results following consultation with Reproducibility Project staff and the authors of the original paper. We have also added some clarifications regarding the Implicit Association Test scoring algorithm, following further conversations with the original authors. The current protocol was written and registered after data collection was complete, but before testing or examining any results and after conferring with the original authors.
