Jeff Kline is a game theorist who studied economics and game theory at Virginia Polytechnic Institute receiving his PhD for work on games of imperfect recall in 1994. Since then, has be teaching economics and game theory in Australia at the Australian National University, Bond University and currently at the University of Queensland. His research areas include decision theory and game theory with applications to industrial organization, contract theory, inductive game theory, ambiguity and unawareness. Jeff Kline has been developing the Inductive Game Theory (IGT) with collaborators in Australia, Belgium, China and Japan over the past 10 years. It is a theory about the experiential foundations of individual beliefs on a social situation. The theory initiated by Kaneko-Matsui (1999), aims to study the emergence of the subjective views of individuals in a recurrent social situation. It provides an experiential source for a player's knowledge about the rules of the game. This can be contrasted to the classical game theory assumption that each player is fully cognizant of the rules of the game (Luce-Raiffa (1957, p. 49)). Kaneko-Matsui explored general issues and potential difficulties with emerging individual views in IGT due to limited experiences. Kaneko-Kline (2008, 2013) considered experiential learning in general extensive games with limited experiences and bounded memory. They explored a general scenario of interactive evolutions of individual views on a social situation and the associated behaviour. The term induction in IGT is used in the sense of science and philosophy. The term mathematical induction looks similar, but it is actually a deductive principle (Mendelson (1987)). Scientific and philosophical induction means that general properties are derived from a finite number of pieces of evidence. This method is applied by scientists to natural and social phenomena. IGT applies the same idea to an ordinary person's understanding of a social situation. This induction gives the source for each player's knowledge about the rules of the game. The induction of IGT involves several different aspects such as the accumulation of memories and the process of cooking (or combining) those memories to construct a view. Because of multiple research targets, the above papers did not discuss the induction process of constructing a view itself; instead, they adopted coherency conditions on the resultant outcome of the process. In the more recent developments of Kline-Lavendhomme-Waltener (2018), the inductive process itself becomes a target.
