This is the personal academic homepage of Dr. Roland Poellinger, researcher in the project group Philosophy of Pharmacology (ERC grant 639276) at the Munich Center for Mathematical Philosophy (MCMP/LMU) and associate faculty member of the Doctoral School of Philosophy at the University of Pécs, Hungary (PTE). His main research interests center around philosophy of science (causal modeling and probabilistic reasoning in Bayesian networks) and logic (algorithmic methods and computability). In 2016 he is teaching formal epistemology as well as topics from the philosophy of causality at LMU Munich and will give a course on causal inference in Bayesian networks at the Forum for Artificial Intelligence Research, University of Stellenbosch (South Africa). He is exploring ways of communicating science across audiences to shape new channels for mathematical philosophy. [More in About]

Abstract: Listing The Nonreductivist’s Troubles with Mental Causation (1993) Jaegwon Kim suggested that the only remaining alternatives are the eliminativist’s standpoint or plain denial of the mind’s causal powers if we want to uphold the closure of the physical and reject causal overdetermination at the same time. Nevertheless, explaining stock market trends by referring to investors’ fear of loss is a very familiar example of attributing reality to both domains and acknowledging the mind’s interaction with the world: "if you pick a physical event and trace its causal ancestry or posterity, you may run into mental events" (Kim 1993). In this talk I will use the formal framework of Bayes net causal models in an interventionist understanding (as devised, e.g., by Judea Pearl in Causality, 2000) to make the concept of causal influence precise. Investigating structurally similar cases of conflicting causal intuitions will motivate a natural extension of the interventionist Bayes net framework, Causal Knowledge Patterns, in which our intuition that the mind makes a difference finds an expression.

Auf Du und Du mit Statistik und Co. (Oktober 2016)

Im Wintersemester 2016/17 veranstaltet das Studienbüro Statistik zusammen mit dem Center for Mathematical Philosophy (MCMP) der LMU erneut das Propädeutikum "Auf Du und Du mit Statistik und Co." als Einführung in formal(isiert)es Denken und empirisches Argumentieren.
Idee und Motivation: Formale Techniken und Argumentationen besitzen auch in den Sozial-, Geistes- und Wirtschaftswissenschaften eine große, und immer weiter wachsende, Bedeutung, stellen aber für viele, darauf nicht so gut vorbereitete Studierende eine sehr große Hürde dar. Im Rahmen eines fachübergreifenden Propädeutikums sollen nichtmathematikaffine Studierende der LMU sanft in die Formalisierung eingeführt und mit wesentlichen Techniken (wieder) vertraut gemacht werden.
Seminar on the Probability of Game-Theoretic Probability (March/April 2016)

In March, 2016, Roland Poellinger will teach topics from the “Philosophy of Game-Theoretic Probability” (co-teaching with Barbara Osimani and Jürgen Landes; co-organized with Prof. Dr. Thomas Augustin from LMU’s department of statistics). The core of the seminar will consist of a lecture series on the philosophy of game-theoretic probability by guest lecturer Glenn Shafer (Rutgers). Students of LMU Munich can sign up for this course through LMU’s LSF system and earn ECTS credit points for participation plus essay.
"Formal Informal: Imprecise Probabilities" | MCMP joint event with Foundations of Statistics (4 Feb, 2013)

On Monday, 4 February, 2013, the MCMP is meeting the LMU Stats Department once again: The third edition of our series "Formal Informal" will center about "Imprecise Probabilities" this time. Join us for the discussion in an open round at 6:00pm, Alte Bibliothek, room 245 (Ludwigstraße 33). Presenters will be Thomas Augustin (Statistics/LMU), Radin Dardashti (MCMP/LMU), Marco Cattaneo (Statistics/LMU), Seamus Bradley (MCMP/LMU), and Stephan Hartmann (MCMP/LMU).
From the manifesto: Probability plays a fundamental role in our attempt to grasp and quantify uncertainty. However, considering the common case of limited knowledge about an event, the assignment of precise probabilities can be regarded as a limitation of the approach. Generalising probability theory to imprecise or interval probabilities offers a broader framework within which to discuss uncertainty. This approach has recently become quite popular due to its successful applications in many areas, ranging from social epistemology to econometrics and artificial intelligence.
This edition of Formal Informal will discuss foundations, applications, and problems of Imprecise Probabilities within statistics, philosophy, and physics.

Imprecise prediction and reliability in intervals - talk at WPMSIIP'12 (13 September, 2012)

On 13 September, 2012, Roland Poellinger gives a talk at the Fifth Workshop on Principles and Methods of Statistical Inference with Interval Probability (WPMSIIP'12) in Munich, the title: "Superimposing Imprecise Evidence onto Stable Causal Knowledge: Analyzing ‘Prediction’ in the Newcomb Case". The talk sketches a possible extension of the CKP framework and outlines an agenda for introducing interval probabilities into causal reasoning, where specific concepts need to be formalized in an imprecise way – (un)reliability as quality of prediction in the Newcomb case. From the abstract:
In this talk I will prepare the ground for a understanding of causality that enables the causal decision theorist to answer Nozick’s challenge with the solution of one-boxing by drawing on the framework of causal knowledge patterns, i.e., Bayes net causal models built upon stable causal relations (cf. Pearl 1995 and 2000/2009) augmented by non-causal knowledge (epistemic contours). This rendition allows the careful re-examination of all relevant notions in the original story and facilitates approaching the following questions:
- How may causality in general be understood to allow causal inference from hybrid patterns encoding subjective knowledge?
- How can the notion of prediction be analyzed – philosophically and formally?
- If all relations given in the model represent stable causal knowledge, how can imprecise evidence be embedded formally? Or in other words: How can the unreliable predictor be modeled without discarding the core structure?
Finally, in what way could unreliable prediction be modeled with interval probability, as motivated by considerations in Nozick’s treatise? And what should be the interpretation of such a rendition?
