• ability to reproduce results by a peer
• requires data, methods, and procedures
• increasingly, science is supposed to be reproducible

Some opinions on whether reproducibility is needed:

• Ideally, yes but we don't have time for this.
• If it gets published, yes.
• If it gets published, yes; unless it is in PLoS One…
• No need: I work on my own.
• For others to copy us? You crazy?!
• No way! We rigged the data, the method does not work, and we ran the analyses in Excel.
