Abstract\u200a: It can be argued (cf. Dizadji\u2011Bahmani et al. 2010) that an increase in
\ncoherence is one goal that drives reductionist enterprises. Consequently, the
\nquestion if or how well this goal is achieved can serve as an epistemic criterion
\nfor evaluating both a concrete case of a purported reduction and our model of
\nreduction\u200a: what conditions on the model allow for an increase in coherence\u200a?
\nIn order to answer this question, I provide an analysis of the relation between
\nthe reduction and the coherence of two theories. The underlying model of
\nreduction is a (generalised) Nagelian model (cf. Nagel 1970, Schaffner 1974,
\nDizadji\u2011Bahmani et al. 2010). For coherence, different measures have been put
\nforward (e.g. Shogenji 1999, Olsson 2002, Fitelson 2003, Bovens & Hartmann
\n2003). However, since there are counterexamples to each proposed coherence
\nmeasure, we should be careful that the analysis be sufficiently stable (in a sense
\nto be specified). It will turn out that this can be done.<\/p>\n

Keywords\u200a: Nagelian reduction, Coherence, Bayesian coherence measures,
