Title: The Replication Crisis, Research Programs, and Theoretical Progress

Abstract: In the social and behavioral sciences, the main strategy to obtain empirical effects remains null-hypothesis significance testing (NHST). But recent attempts to replicate allegedly well-established empirical effects have failed. Hence, NHST retains too many errors. Otherwise many more such effects should have been replicated successfully. This makes trusting even results that top-tier journals publish a true difficulty. We advocate the research program strategy (RPS) as superior to NHST. Employing both Frequentist NHST-elements and elements of Bayesian hypothesis-testing (BHT), we show by means of data-simulation that RPS’s six steps—leading from a discovery against a random model to a statistically verified hypothesis—retain fewer errors, and thus deserve greater trust, than NHST- or BHT-results. Computer simulations moreover serve to estimate the expectable proportion of such errors among published results. Generally, if test-power is unknown, then NHST constitutes RPS’s first step, where probabilities serve to discover an effect preliminarily. If we know test-power, by contrast, then a substantial discovery may arise (step 2). Moving beyond discoveries, steps 3 to 6 concern the justification of hypotheses (probabilistic falsification and verification) using likelihood-ratios, which differ in epistemologically important ways from BHT’s Bayes Factors. RPS’s six steps generally presuppose data of high induction quality (test-power) to properly test hypotheses. As a threshold for sufficient support, we employ Wald’s criterion (the ratio of test-power and significance level) to preliminarily or substantially falsify H0 (steps 3, 4), and again to preliminary verify H1 (step 5). Finally, if the ratio of the likelihoods for H1 and H0 exceeds Wald’s criterion, while the maximum-likelihood-estimate of data lies close to H1, then this substantially verifies H1 (step 6). Though this work draws on inferential statistics, a strong formal background is not necessary to profit from the talk, which is based, among others, on these publications:

Title: Probabilism without (Substantive) Arguments
Abstract: Probabilism is a popular view about the rational requirements governing thoughts about what is likely and unlikely, which says that the strengths of such thoughts for a person should conform to the laws of probability. The formal epistemology literature contains several complex and controversial arguments in favor of Probabilism. In this paper I will neither advocate for nor challenge any particular such argument. Instead, I will show how, if we adopt a simple, alternative account of the nature of thoughts about what is likely, Probabilism requires no substantive argument to support it; it follows trivially from the nature of these attitudes and their contents. I suggest that this is a strong, though not decisive, reason against the picture of such thoughts that is standard in formal epistemology.

Metaphysics of Abstract Artifacts: A New Reading Group at Boğaziçi on Mondays

leave a comment »

I am starting a new reading group on the metaphysics of abstract artifacts. Some objects such as musical works, novels, fictional characters, computer programs do not seem to fit the traditional ontological categories of either concrete or abstract. The distinction between these two categories is usually drawn on account of whether having or lacking spatiotemporal location, or causal efficacy. I call these objects abstract artifacts. Abstract artifacts, if they exist, seem to be created by composers/authors/programmers, etc. and thus have a beginning in time, yet they seem to be abstract objects of some kind (since they lack spatial location, or they are multiply realizable and/or repeatable). However, abstract objects are presumably causally inert; they cannot push or pull things. If creation entails being caused to exist, then it seems that the abstract objects in question cannot be created. Hence, it seems we have to give up on one of the above claims about abstract artifacts. This is often referred to as the paradox of standards.

We will begin our discussion trying to answer the question how we solve this puzzle. In this reading group, we will start with a basic ontological framework in which the questions and alternative proposal are construed, and then move on to more difficult questions about the nature of abstract artifacts. Most of our discussions will focus on the ontology of works of art but we will keep in mind the possibility that whatever we say about works of art might shed some light on different kinds of abstract artifacts: linguistic entities such as letters, words, languages, computer programs and, perhaps, scientific theorems.

The reading group will be meeting on Mondays (starting from Monday, Feb 27) from 5:15 to 7 pm at JF (John Freely Hall) 507, Bogazici University South Campus. Everyone is welcome.

For the first week we will be reading two survey papers on abstract objects: Gideon Rosen’s SEP entry “Abstract Objects” and Linda Wetzel’s “Types and Tokens”.

If you want to join our email list, please email Ozcan Karabag at ahmetozcankarabag@gmail.com.

This reading group is organized as part of Nurbay Irmak’s BAP project “Concept Pluralism and Artifactual Theory of Language” (10321).
