(TRABAJO ENVIADO: 15/10/2008; ACEPTADO: 17/2/2009; PUBLICADO: 9/3/2009). It is shown that quantum systems of identical particles can be treated as different when they are in well-differentiated states. This simplifying assumption allows for the consideration of quantum systems isolated from the rest of the universe and justifies many intuitive statements about identical systems. However, it is shown that this simplification may lead to wrong results in the calculation of the entropy.
