Two responses have now been published to the Vandenbroucke-Broadbent-Pearce paper on Potential Outcomes in IJE (Jan 2016).

• Tyler J. VanderWeele, Miguel A. Hernán, Eric J. Tchetgen Tchetgen, and James M. Robins. Letter to the Editor. Re: Causality and causal inference in epidemiology: the need for a pluralistic approach.
• Arnaud Chiolero. Letter to the Editor. Counterfactual and interventionist approach to cure risk factor epidemiology.

We have replied to these letters (open access).

• Broadbent, A., Pearce, N., and Vandenbroucke, J. Authors’ Reply to: VanderWeele et al., Chiolero, and Schooling et al.

As well as this exchange of letters, the IJE has asked for some fuller commentaries on our paper, as well as our response to these commentaries. The exchange is developing in an extremely useful way, in my view, and I look forward to being able to share the next “round”, perhaps later this year.

Our original paper is here.
