In this work, we clarify the relationship between the information that an agent receives from a signal, from an experiment or from his own ability to determine the true state of nature that occurs and the information that an agent receives from a $$\sigma $$ -algebra. We show that, for countably generated $$\sigma $$ -algebras, the larger it is, the larger the information is. The same is true for general $$\sigma $$ -algebras after the removal of a negligible set of states. Copyright Springer-Verlag Berlin Heidelberg 2013
