Population synthesis models are a tool extensively used to make
inferences about the evolutionary status of stellar populations. In this
work I examine the implicit priors assumed to obtain inferences by
comparing observational data with populations synthesis models. As a
result from this kind of study, I show how a higher spatial resolution
can be used to obtain better global (but not spatially detailed)
properties of the system. I also show that a pixel-by-pixel (or IFU by
IFU) analysis would provide biased results unless they take into account
the correlations of stellar populations between different resolution
elements (pixels or IFUs) and a prior hypothesis on the projected
stellar mass distribution (equivalent to a prior hypothesis on the star
formation history)
