El problema de la base privilegiada consiste en dar cuenta de la base que define el observable medido en una medición cuántica, dada la supuesta ambigüedad teórica en la definición de dicho observable. El propósito del presente artículo es analizar este problema escasamente explorado. El objetivo final es argumentar que, contrariamente a la opinión más difundida, la teoría de la decoherencia no aporta una solución a dicho problema, no debido a su propia incapacidad, sino porque, en realidad, se trata de un pseudo-problema que no requiere solución alguna.
