**Purpose of this page** This OSF project page describes our procedures as part of the *Perspectives on Psychological Science* Registered Replication Report of the following study: - Rand, D. G., Greene, J. D., & Nowak, M. A. (2012) Spontaneous giving and calculated greed. Nature, 489, 427–430. Please consult the official [protocol][1] and [RRR project page][2] for details of the experiment's methodology, all of the materials necessary for the project, and detailed instructions. This project page describes our implementation of this protocol, with details provided in the Implementation component. Inadvertently, we didn't pre-register the protocol, although we did follow exactly the protocol described in the OSF page protocol and it was not modified during data collection. **Contributors** - Thorsten Chmura, University of Nottingham Business School - Roberto Hernán-González, University of Nottingham Business School [1]: https://osf.io/ypd78/ [2]: https://osf.io/scu2f/
