The Accelerated CREP partnership study will attempt to replicate Turri et al (2015). https://psysciacc.org/2018/04/08/the-accelerated-crep/ - Turri, J., Buckwalter, W., & Blouw, P. (2015). Knowledge and luck. *Psychonomic Bulletin & Review, 22*(2), 378-390. **Chief Researcher**: Dr. Jennifer Beaudry <br> **Student Researcher**: Elian Thiele-Evans <br> **Project Number**: AC 2055 <br> **Overview** We completed this replication of Turri et al. (2015) Experiment 1 at Swinburne University of Technology in Melbourne, Victoria, Australia. The study is running as a large-scale, multi-site replication under the [Accelerated CREP][1]. We are not extending this study; we will follow the procedure detailed in the Stage 1 Registered Report by Hall et al. (2019). **Methods** Participants read three vignettes (Darryl, Emma, Gerald), randomly assigned and counterbalanced into one of the three belief conditions (the ignorance control, the Gettier case, and the knowledge control). The three vignettes were presented in random order. After each vignette, participants completed the knowledge attribution question, a comprehension question, and then a reasonableness question. After completing the three vignettes, participants were asked to complete demographic questions. **Sample** Participants (N = 165) students enrolled in first-year Psychology units were recruited from the Swinburne University of Technology undergraduate student pool (known as the Research Experience Program or REP). Participants received 0.5 REP credits for participating in this study. **Data** To anonymise the data, we deleted the IP address column from the raw data files. We have not analysed the data (as per a discussion with Jordan Wagge in February 2020), but it appears as though all but 2 participants completed the key variables in the study (i.e. Qualtrics progress rates of => 98%). As such, we estimate that our final sample is 163 participants. We do not include a codebook of our results because we used the same Qualtrics survey provided to us by the CREP team. We did not edit the Qualtrics survey except to include the consent and debriefing details required by our university's ethics review board. >**Turri et al. (2015)** **Abstract**: Nearly all success is due to some mix of ability and luck. But some successes we attribute to the agent's ability, whereas others we attribute to luck. To better understand the criteria distinguishing credit from luck, we conducted a series of four studies on knowledge attributions. Knowledge is an achievement that involves reaching the truth. But many factors affecting the truth are beyond our control, and reaching the truth is often partly due to luck. Which sorts of luck are compatible with knowledge? We found that knowledge attributions are highly sensitive to lucky events that change the explanation for why a belief is true. By contrast, knowledge attributions are surprisingly insensitive to lucky events that threaten, but ultimately fail to change the explanation for why a belief is true. These results shed light on our concept of knowledge, help explain apparent inconsistencies in prior work on knowledge attributions, and constitute progress toward a general understanding of the relation between success and luck.
