Concerns with the SDT approach to causal conditional reasoning: a comment on Trippas, Handley, Verde, Roser, McNair, and Evans (2014).

The author reflects on a study that utilized signal detection theory (SDT) approach to causal conditional reasoning, and mentions that SDT model is often unable to provide an informative characterization of data in, as it fails to separate argument strength and response bias. The authors further opine that reliance on receiver operating characteristics (ROC) shape in the study, to justify a separation between affirmation and denial problems, is unnecessary and misguided.
