English: The ladder of inference is metaphorical model, created by Chris Argyris (1923–2013), of how people take action based on an often unconscious process of inference from the flux or pool of observable "data". Argyris's original ladder had fewer rungs with different names.
Judea Pearl defines a causal model as an ordered triple ,, , where U is a set of exogenous variables whose values are determined by factors outside the model; V is a set of endogenous variables whose values are determined by factors within the model; and E is a set of structural equations that express the value of each endogenous variable as a function of the values of the other variables in U ...
Chris Argyris (July 16, 1923 – November 16, 2013 [1]) was an American business theorist and professor at Yale School of Management and Harvard Business School.Argyris, like Richard Beckhard, Edgar Schein and Warren Bennis, [citation needed] is known as a co-founder of organization development, and known for seminal work on learning organizations.
This chapter looks at the 'second rung' of the ladder of causation introduced in chapter 1. The authors describe how to use causal diagrams to ascertain the causal effect of performing interventions (eg. smoking) on outcomes (such as lung cancer). The 'front-door criterion' and the 'do-calculus' are introduced as tools for doing this.
A standard representation of the pyramid form of DIKW models, from 2007 and earlier [1] [2]. The DIKW pyramid, also known variously as the knowledge pyramid, knowledge hierarchy, information hierarchy, [1]: 163 DIKW hierarchy, wisdom hierarchy, data pyramid, and information pyramid, [citation needed] sometimes also stylized as a chain, [3]: 15 [4] refer to models of possible structural and ...
An influence diagram (ID) (also called a relevance diagram, decision diagram or a decision network) is a compact graphical and mathematical representation of a decision situation. It is a generalization of a Bayesian network , in which not only probabilistic inference problems but also decision making problems (following the maximum expected ...

Causal graphs can be used for communication and for inference. They are complementary to other forms of causal reasoning, for instance using causal equality notation . As communication devices, the graphs provide formal and transparent representation of the causal assumptions that researchers may wish to convey and defend.
