Does Libet’s experiment really speak about freedom?

In this poster I discuss the experiments of Libet and colleagues on conscious decisions, but my conclusions are also valid for other experiments inspired in it. The discussion concentrates on the concept of freedom which is presupposed in the experiment, and especially by those who interpret its results as a denial of the existence of human free will. I aim to show how a philosophical approach is also needed in the designs and interpretation of experimental data when important non-empirical human features are at stake
