**Target of replication:** The key analyses in support of this focused on differences in cheating rates between conditions, and on correlations between the manipulation check (the free will scale by Paulhus & Margesson, 1994) and the cheating outcome.
**Summary of differences between RP:P & ML:5:**
1. ***Free-Will Manipulation***
The original study and the RP:P replication used passages from Francis Crick’s The Astonishing Hypothesis which may have been too difficult for participants to understand. We therefore will use the free-will manipulation of Alquist, Ainsworth, and Baumeister (2012), which is based on the same Crick passages, but which may be more convincing to a broader range of participants.
2. ***Free-Will Measurement*** The original study and the RP:P replication used an unpublished scale by Paulhus & Margesson (1994) to measure belief in free will, which turned out to have questionable reliability. More recently, Paulhus & Carey (2011) have further developed and refined the scale, creating a more psychometrically-stable measuring tool, which we will use instead.
