  This paper aims to falsify the hypothesis that the observer's consciousness
is necessary for quantum measurement. To achieve our target, we propose a
variation of the Schroedinger's cat thought experiment called "DAP", short for
"Dead-Alive Physicist", in which a human being replaces the cat. This strategy
enables us to logically disprove the consistency of the above hypothesis and to
oblige its supporters either to be trapped in solipsism or to rely on an
alternative interpretation of quantum mechanics in which the role of the
conscious observer has to be reviewed. Our analysis hence provides support to
clarify the relationship between the observer the objects of her/his
experimental observation; this and a few other implications are discussed in
the fourth section and in the conclusions.
