The measurement problem is often considered an inconsistency inside the quantum formalism. Even though it is now generally agreed that it is not the case, decoherence has sometimes been viewed as a possible solution. I will show that it is indeed not the case and will present what decoherence actually brings and which the problems we are left with are. I will then propose a possible solution to the measurement problem taking the role of the observer into account.
