There is a worldwide increase in the incidence of type 1 diabetes (1–3). This increase, in conjunction with the lack of complete concordance in monozygotic twin pairs, points to the importance of environmental factors (3).

In this paper we propose a conditional logic IBC to represent iterated belief revision. We define an iterated belief revision system by strengthening the postulates proposed by Darwiche and Pearl [3]. First, following the line of Darwiche and Pearl, we modify AGM postulates to make belief revision a function of epistemic states rather than of belief sets. Then we propose a set of postulates for...
