The variety of evidence thesis and its independence of degrees of independence

The intuitive Variety of Evidence Thesis states that, ceteris paribus, more varied evidence for a hypothesis confirms it more strongly than less varied evidence. Recent Bayesian analyses have raised serious doubts in its validity. Claveau suggests the existence of a novel type of counter-example to this thesis: a gradual increase in source independence can lead to a decrease in hypothesis confirmation. I show that Claveau's measure of gradual source independence suffers from two unsuspected types of inconsistencies. I hence put forward a more natural measure of gradual source independence which is not plagued by inconsistencies. Claveau's counter-examples to the variety of evidence thesis disappear with the measure I suggest. I hence argue that my measure is preferable and that this thesis does at least not seem to be troubled by Claveau's arguments.
