Under the hypothesis that every attribution of responsibility rests on the fact that an expectation has been breached, the author proposes to understand expectations as standards adopted by a community to evaluate specific events and allow the members of the community to search for an explanation of the events which breach expectations. After presenting this way of understanding expectations, their relationship with responsibility is analyzed, having in mind the mentioned hypothesis. To close the paper, the relationship between responsibility and expectations (...) is explored as an alternative to the idea that every attribution of responsibility supposes the breach of an obligation, whether moral or legal, by who is held responsible.
