The authors begin this brief rejoinder by thanking all the authors who took time to provide comments on their work, which appeared in "Measurement: Interdisciplinary Research and Perspectives" v14 n3 2016. All commentaries appear to suggest that causal indicators cannot be used for measurement but differ in how strongly this conclusion is stated; commentaries challenging our work and its conclusions are notably absent. In this article the authors outline some common themes across the commentaries, provide some thoughts on these themes, and outline areas they believe need further research.
