In an attempt to test the limits of the current interpretation of quantum mechanics, according to which microscopic systems are always in a superposition of states, A. Leggett has proposed the thesis of macrorealism, according to which quantum mechanical superpositions of macroscopically distinct states never occur. Leggett has also shown the basic features of some experimental tests that would decide definitively between quantum mechanics and macrorealism. In this paper I present some basic elements of the standard interpretation of quantum mechanics and of macrorealism, in order to make evident that the experimental results may well be more open to interpretation than Leggett himself would accept. Among such interpretations I highlight the possibility of undertanding the results as examples of violations of the principle of induction in which macrorealism rests, opening the door for solving the tension between QM and macrorealism in terms of the backwards causatio, according to which there is no need for appealing to any special role played by either observers or measurement apparatuses in order to explain what differentiates quantum systems from macroscopic ones, a difference that could now be defined partly in terms of their causal and temporal directionality.
