WORKSHOP ON BAYESIAN ARGUMENTATION
Lund, Sweden
22 & 23 October 2010

Introduction

Funded by the Wenner-Gren Foundations and the Swedish Research Council.

Treatments of natural language argumentation by means of Bayes theorem (BT) are 
a comparatively recent phenomenon. The basic idea behind (BT) is that the 
probability of a hypothesis increases to the extent that evidence is more 
likely if the hypothesis were true than if it were false. To fit this idea to 
natural language arguments (and episodes of reasoning thus suggested), the term 
??evidence?? is interpreted as reason or ground, and the term ??hypothesis?? as 
conclusion or proposal. The choice always depends also on particular ways of 
drawing the distinction between theoretical and practical reasoning.

Amongst others, (BT) can be used as a measure for the rational assignment of 
degrees of belief in the face of new evidence. It also provides expression for 
qualitative demands such as the significance of the likelihood-difference 
between mutually exclusive, but equally data-fitting hypotheses or ?? in the 
non hypothesis-testing context ?? equally grounds-covering proposals. In 
principle, then, agreement and disagreement may be rationally constrained both 
within and across agents (including epistemic peers) by what effectively is a 
quantitative measure of relative argument strength.

Further applications of (BT) pertain, for example, to statistical fallacies and 
decision making under uncertainty. This international workshops seeks to 
collect recent results in this area, collect participant??s papers in a special 
issue of an international journal, and to explore avenues for future 
cooperation.
