Correction to: Palgrave Communications (2017) 3 Article number: 17032 doi:10.1057/palcomms.2017.32; Published 2 May 2017; Updated 16 May 2017

The article previously lacked some information in the Acknowledgements section.

The original text read:

Acknowledgements

The authors thank all participants for filling out our online questionnaire, and for personal feedback. They further thank the mail list administrators and societies for posting our questionnaire. Specifically we would like to thank colleagues who participated in trial runs of the questionnaire and helped to improve the survey.

This has now been updated to read:
