This article is a commentary on the Focus Article, "Interpretational Confounding or Confounded Interpretations of Causal Indicators?" and a commentary that was published in issue 12(4) 2014 of "Measurement: Interdisciplinary Research & Perspectives". The authors challenge two claims: (a) Bainter and Bollen argue that the latent variable defined by causal indicators (possessing conceptual unity) do not suffer from instability of the formative measurement model. Bainter and Bollen performed simulations to justify their claim. Guyon and Tensaout applaud Bainter and Bollen's work here because it seems that these Monte Carlo simulations are the first simulations published for the purpose of discussing the stability of formative measurement models; (b) in contrast, Howell considers that the causal indicators do not explain the meaning of the formative latent variable because this meaning "is entirely in the ys" (p. 142).
