About

Alexandru Marcoci

I am a Fellow in the Department of Government at LSE and before that I was a PhD student in the Department of Philosophy, Logic and Scientific Method. I divide my research time between the following projects. Firstly, together with James Nguyen I investigate whether large scientific collaborations can be treated as group agents. Secondly, I collaborate with the SWARM project and together with Mark Burgman and Ans Vercammen I develop and test rubrics for evaluating the quality of reasoning in intelligence reports. Thirdly, Luc Bovens and I argue for a more inclusive policy for bathroom access. Finally, I work together with Diana Popescu on an abstract model explaining ideological polarization.

2018. A. Marcoci and J. Nguyen. Objectivity, Ambiguity and Theory Choice. Erkenntnis Abstract

Kuhn argued that scientific theory choice is, in some sense, a rational matter, but one that is not fully determined by shared objective scientific virtues like accuracy, simplicity, and scope. Okasha imports Arrow's impossibility theorem into the context of theory choice to show that rather than not fully determining theory choice, these virtues cannot determine it at all. If Okasha is right, then there is no function (satisfying certain desirable conditions) from 'preference' rankings supplied by scientific virtues over competing theories (or models, or hypotheses) to a single all-things-considered ranking. This threatens the rationality of science. In this paper we show that if Kuhn's claims about the role that subjective elements play in theory choice are taken seriously, then the threat dissolves.

2017. A. Marcoci and J. Nguyen. Scientific Rationality by Degrees. In M. Massimi, J.W. Romeijn, and G. Schurz (eds.) EPSA15 Selected Papers. European Studies in Philosophy of Science, Vol. 5 (Springer) Abstract

In a recent paper, Samir Okasha imports Arrow's impossibility theorem into the context of theory choice. He shows that there is no function (satisfying certain desirable conditions) from profiles of preference rankings over competing theories, models or hypotheses provided by scientific virtues to a single all-things-considered ranking. This is a prima facie threat to the rationality of theory choice. In this paper we show this threat relies on an all-or-nothing understanding of scientific rationality and articulate instead a notion of rationality by degrees. The move from all-or-nothing rationality to rationality by degrees will allow us to argue that theory choice can be rational enough.

Under review

A. Marcoci. Monty Hall saves Dr. Evil: On Elga's Restricted Principle of Indifference. Major revisions in progress Abstract

In this paper I show that Elga's argument for a restricted principle of indifference for self-locating belief relies on the kind of mistaken reasoning that recommends the 'staying' strategy in the Monty Hall problem.

A. Marcoci. On the dilemma of redistribution. Abstract

McKenzie Alexander (2013) presents a dilemma for a social planner who wants to correct an unfair distribution of an indivisible good between two equally worthy individuals or groups: either she guarantees a fair outcome, or she follows a fair procedure (but not both). In this paper I show that this dilemma only holds if the social planner can redistribute the good in question at most once. To wit, the bias of the initial distribution always washes out when we allow for sufficiently many redistributions.

L. Bovens and A. Marcoci. An efficiency argument for unisex restrooms. Abstract

Recently there has been much public debate regarding whether restroom access should be linked to one's sex at birth. To make some headway, we propose a new way of framing the issue—one we hope will provide some common ground among all groups. Our idea is simple: let's talk about the (economic) efficiency of more inclusive facilities. The move to unisex restrooms increases economic efficiency in two ways. First, if we preserve the current architecture, then opening all stalls to everyone leads to a drastic reduction in waiting times. Second, if we respect the maximum waiting time that is implicitly allowed by current legislation, then by moving to a unisex policy we can eliminate facilities while attaining the same waiting times. Since all parties to the debate have reason to care about efficiency, there is at least one argument in favour of inclusive restrooms that all can agree on.

Teaching

This year I am teaching GV100 Introduction to Political Theory. Below you can find the webpages of two courses I taught in the past.

award In 2017 I received the Department of Government's Class Teacher Award and I was a finalist in the Students' Union Teaching Excellence Awards for Sharing Subject Knowledge. In 2015 I was awarded a Honourable Commendation for Excellent Class Teaching by the Department of Philosophy, Logic and Scientific Method. In 2014 I won the Students' Union Teaching Excellence Award for Collaborative Research and Guidance.
