Although the causal graphical model framework has achieved success accounting for numerous causal-based judgments, a key property of these models, the Markov condition, is consistently violated (Rehder, 2014; Rehder & Davis, 2016). A new process model—the causal sampler—accounts for these effects in a psychologically plausible manner by assuming that people construct their causal representation...

In this paper it will be argued that causal laws describe the actions of causal powers. The process which results from such an action is one which belongs to a natural kind, the essence of which is that it is a display of this causal power. Therefore, if anything has a given causal power necessarily, it must be naturally disposed to act in the manner prescribed by the causal law describing the ...

Causal explanation takes place in and takes the form of conversation. Explanations are selected by questions and are thus governed by general rules of discourse. A conversational model of causal explanation is introduced that explicates social aspects of the explanation process by postulating that good explanations must be relevant to the focus of a why question, as well as being true. The noti...

A ‘process theory’ is any theory of systems and processes which admits sequential and parallel composition. ‘Terminality’ unifies normalisation of pure states, trace-preservation of CP-maps, and adding up to identity of positive operators in quantum theory, and generalises this to arbitrary process theories. We show that terminality and non-signalling coincide in any process theory, provided on...

We propose a framework for building graphical decision models from individual causal mechanisms. Our approach is based on the work of Simon [Simon, H.A., 1953. Causal ordering and identifiability.
