The science part of photography is a given ... the price of entry. You have to grasp the principles at play to be able to even make art ... or at least artistically control the making of a photograph.
I think what may be the point of dispute here is one of perspective and degree.
I for one am not even slightly interested in the science of photography for its own sake ... especially the science of digital photography. Not that it isn't interesting and valuable for making art, it's just that for me it is not necessary to know how "the sausage is made".
I tend to evaluate based on use and experience ... therefore gravitate to listening to the opinions of others who's work I admire or respect that have actually used the gear being evaluated to do their work... especially if the work is similar to what I do.
So, I do not place anecdotal experience at the bottom of the heap of information sources, I place it at the top.
Different strokes for different folks.
