Bayesianism is the claim that scientific reasoning is\ud
probabilistic, and that probabilities are adequately interpreted\ud
as an agent"s actual subjective degrees of belief\ud
measured by her betting behaviour.\ud
Confirmation is one important aspect of scientific reasoning.\ud
The thesis of this paper is the following: Given that\ud
scientific reasoning (and thus confirmation) is at all\ud
probabilistic, the subjective interpretation of probability has\ud
to be given up in order to get right confirmation, and thus\ud
scientific reasoning in general
