    In Search of the Climate Change Filter Bubble : A Content-Based Method for Studying Ideological Segregation in Google.Emmanuel Genot, Magnus Jiborn, Ulrike Hahn, Igor Volzhanin, Erik J. Olsson & Ylva von Gerber - unknown
    : A popular belief is that the process whereby search engines tailor their search results to individual users, so-called personalization, leads to filter bubbles in the sense of ideologically segregated search results that would tend to reinforce the user’s prior view. Since filter bubbles are thought to be detrimental to society, there have been calls for further legal regulation of search engines beyond the so-called Right to be Forgotten Act. However, the scientific evidence for the filter bubble hypothesis is surprisingly (...)

  3. The Game of Inquiry: The Interrogative Approach to Inquiry and Belief Revision Theory.Emmanuel Genot - 2009 - Synthese 171 (2):271-289.
    I. Levi has advocated a decision-theoretic account of belief revision. We argue that the game-theoretic framework of Interrogative Inquiry Games, proposed by J. Hintikka, can extend and clarify this account. We show that some strategic use of the game rules generate Expansions, Contractions and Revisions, and we give representation results. We then extend the framework to represent explicitly sources of answers, and apply it to discuss the Recovery Postulate. We conclude with some remarks about the potential extensions of interrogative games, (...)

    The Dissemination of Fake Science : On the Ranking of Retracted Articles in Google.Emmanuel Genot & Erik J. Olsson - forthcoming - In S. Bernecker, A. K. Flowerree & T. Grundmann (eds.), The Epistemology of Fake News.
    Fake news can originate from an ordinary person carelessly posting what turns out to be false information orfrom the intentional actions of fake news factory workers,but broadly speaking it can also originate from scientific fraud. In the latter case, the article can be retracted upon discovery of the fraud. A case study shows, however, that such fake sciencecan be visible in Google even after the article was retracted, in fact more visible thanthe retraction notice. We hypothesize that the reason for (...)

    Strategies of Inquiry : The ‘Sherlock Holmes Sense of Deduction’ Revisited.Emmanuel J. Genot - 2018 - Synthese 195 (5):2065-2088.
    This paper examines critically the reconstruction of the ‘Sherlock Holmes sense of deduction’ proposed jointly by M.B. Hintikka and J. Hintikka in the 1980s, and its successor, the interrogative model of inquiry developed by J. Hintikka and his collaborators in the 1990s. The Hintikkas’ model explicitly used game theory in order to formalize a naturalistic approach to inquiry, but the imi abandoned both the game-theoretic formalism, and the naturalistic approach. It is argued that the latter better supports the claim that (...)

    How Can Questions Be Informative Before They Are Answered? Strategic Information in Interrogative Games.Emmanuel Genot & Justine Jacot - 2012 - Episteme 9 (2):189-204.
    We examine a special case of inquiry games and give an account of the informational import of asking questions. We focus on yes-or-no questions, which always carry information about the questioner's strategy, but never about the state of Nature, and show how strategic information reduces uncertainty through inferences about other players' goals and strategies. This uncertainty cannot always be captured by information structures of classical game theory. We conclude by discussing the connection with Gricean pragmatics and contextual constraints on interpretation.Send (...)

    Logical Dialogues with Explicit Preference Profiles and Strategy Selection.Emmanuel Genot & Justine Jacot - 2017 - Journal of Logic, Language and Information 26 (3):261-291.
    The Barth–Krabbe–Hintikka–Hintikka Problem, independently raised by Barth and Krabbe and Hintikka and Hintikka Sherlock Holmes confronts modern logic: Toward a theory of information-seeking through questioning. Indiana University Press, Bloomington, 1983), is the problem of characterizing the strategic reasoning of the players of dialogical logic and game-theoretic semantics games from rational preferences rather than rules. We solve the problem by providing a set of preferences for players with bounded rationality and specifying strategic inferences from those preferences, for a variant of logical (...)

    Extensive Questions.Emmanuel Genot - 2009 - Lecture Notes in Computer Science 5378:131--145.
    Olsson and his collaborators have proposed an extension of Belief Revision Theory where an epistemic state is modeled as a triple S=⟨K_,E,A_⟩ , where A_ is a research agenda, i.e. a set of research questions. Contraction and expansion apply to states, and affect the agenda. We propose an alternative characterization of the problem of agenda updating, where research questions are viewed as blueprints for research strategies. We offer a unified solution to this problem, and prove it equivalent to Olsson’s own. (...)

    From Reasonable Preferences, Via Argumentation, to Logic.Justine Jacot, Emmanuel Genot & Frank Zenker - 2016 - Journal of Applied Logic 18:105-128.
    This article demonstrates that typical restrictions which are imposed in dialogical logic in order to recover first-order logical consequence from a fragment of natural language argumentation are also forthcoming from preference profiles of boundedly rational players, provided that these players instantiate a specific player type and compute partial strategies. We present two structural rules, which are formulated similarly to closure rules for tableaux proofs that restrict players' strategies to a mapping between games in extensive forms and proof trees. Both rules (...)

    Semantic Games for Algorithmic Players.Emmanuel Genot & Justine Jacot - unknown
    We describe a class of semantic extensive entailment game with algorithmic players, related to game-theoretic semantics, and generalized to classical first-order semantic entailment. Players have preferences for parsimonious spending of computational resources, and compute partial strategies, under qualitative uncertainty about future histories. We prove the existence of local preferences for moves, and strategic fixpoints, that allow to map eeg game-tree to the building rules and closure rules of Smullyan's semantic tableaux. We also exhibit a strategy profile that solves the fixpoint (...)

    The Holmesian logician: Sherlock Holmes’ “Science of Deduction and Analysis” and the logic of discovery.Emmanuel J. Genot - forthcoming - Synthese:1-18.
    This paper examines whether Sherlock Holmes’ “Science of Deduction and Analysis,” as reconstructed by Hintikka and Hintikka The sign of three: Peirce, Dupin, Holmes, Indiana University Press, Bloomington, 1983), exemplifies a logic of discovery. While the Hintikkas claimed it does, their approach remained largely programmatic, and ultimately unsuccessful. Their reconstruction must thus be expanded, in particular to account for the role of memory in inquiry. Pending this expansion, the Hintikkas’ claim is vindicated. However, a tension between the naturalistic aspirations of (...)

    The Best of All PossibleWorlds: Where Interrogative Games Meet Research Agendas.Emmanuel Genot - 2011 - In Erik J. Olson Sebastian Enqvist (ed.), Belief Revision Meets Philosophy of Science. Springer. pp. 225--252.
    Erik J. Olsson and David Westlund have recently argued that the standard belief revision representation of an epistemic state is defective. In order to adequately model an epistemic state one needs, in addition to a belief set K and an entrenchment relation E, a research agenda A, i.e. a set of questions satisfying certain corpus-relative preconditions the agent would like to have answers to. Informally, the preconditions guarantee that the set of potential answers represent a partition of possible expansions of (...)

    Taking Problem-Solving Seriously.Emmanuel Genot & Justine Jacot - unknown
    Instructions in Wason’s Selection Task underdetermine empirical subjects’ representation of the underlying problem, and its admissible solutions. We model the Selection Task as an interrogative learning problem, and reasoning to solutions as: selection of a representation of the problem; and: strategic planning from that representation. We argue that recovering Wason’s ‘normative’ selection is possible only if both stages are constrained further than they are by Wason’s formulation. We conclude comparing our model with other explanatory models, w.r.t. to empirical adequacy, and (...)

    The Brain Attics: The Strategic Role of Memory in Single and Multi-Agent Inquiry.Emmanuel J. Genot & Justine Jacot - 2020 - Synthese 197 (3):1203-1224.
    M. B. Hintikka and J. Hintikka claimed that their reconstruction of the ‘Sherlock Holmes sense of deduction’ can “serve as an explication for the link between intelligence and memory”. The claim is vindicated, first for the single-agent case, where the reconstruction captures strategies for accessing the content of a distributed and associative memory; then, for the multi-agent case, where the reconstruction captures strategies for accessing knowledge distributed in a community. Moreover, the reconstruction of the ‘Sherlock Holmes sense of deduction’ allows (...)

    A Computational Model of Wason's Selection Task.Emmanuel Genot - unknown
    We apply an algorithmic learning model of inquiry to model reasoning carried by experimental subjects in Wason's _Selection Task_ that represents reasoning in the task as computation of a decision tree that supervenes on semantic representations. We argue that the resulting model improves on previous probabilistic and pragmatic models of the task. In particular, it suggests that subjects' selection could in fact be guided by sophisticated patterns of argumentative reasoning.

    In Wason’s Selection Task, subjects: process information from the instructions and build a mental representation of the problem, then: select a course of action to solve the problem,under the constraints imposed by the instructions. We analyze both aspects as part of a constraint satisfaction problem without assuming Wason’s ‘logical’ solution to be the correct one. We show that outcome of step may induce mutually inconsistent constraints, causing subjects to select at step solutions that violate some of them. Our analysis explains (...)

    Semantic Games for First-Order Entailment with Algorithmic Players.Emmanuel Genot & Justine Jacot - unknown
    If semantic consequence is analyzed with extensive games, logical reasoning can be accounted for by looking at how players solve entailment games. However, earlier approaches to game semantics cannot achieve this reduction, by want of explicitly dened preferences for players. Moreover, although entailment games can naturally translate the idea of argumentation about a common ground, a cognitive interpretation is undermined by the complexity of strategic reasoning. We thus describe a class of semantic extensive entailment game with algorithmic players, who have (...)

    The Fall of Reichenbach.Emmanuel Genot - unknown
    Reichenbach’s constraint is the methodological imperative formulated by Reichenbach in the following passage: “If we want to construct a philosophy of science, we have to distinguish carefully between two kinds of context in which scientific theories may be considered. The context of discovery is to be separated from the context of justification; the former belongs to the psychology of scientific discovery, the latter alone is to be the object of the logic of science.” Reichenbach’s constraint is usually understood as barring (...)
