The legitimacy of parsimony stands or falls, in a particular research context, on subject matter specific (and a posteriori) considerations. […] What makes parsimony reasonable in one context may have nothing in common with why it matters in another.
-- Elliot Sober
What could be simpler, and fairer, than refraining from making assumptions about other individuals and refraining from drawing conclusions about them once one has the full set of information that exists about them?
Parsimony is a wonderful thing, but as with all things, context determines what philosophical principle rightly applies. Simplicity for its own sake is of no real value at all. Simplicity in passing judgment on a photo is one thing for, but applying it to the assessment of other humans is a wholly different matter. Individuals of high ethical constitution know when and what it is they don't know about another person, and knowing that, they accord the other person the objectivity they are due from extant doubt.
As I wrote, and it clearly went right past you, we are talking about people, not merely pictures, and the assumptions made about them (currently or in the past, but that yet endure today). Of all the things in the world that are simple, and simply understood and concluded upon, people are not among them.
FWIW, I suggest you read
this. It'll give you a much better understanding of simplicity as a mode of thought and analysis. After reading it, assuming you do read it, you should be able to understand comprehensively why your having invoked Occam is amiss in this context. Prior to the 20th century it was believed that the metaphysical justification for Ockham's Razor was simplicity. It was thought that nature was in some sense simple and that our theories about nature should reflect that simplicity. With such a metaphysical justification came the implication that Ockham's Razor is a metaphysical principle. From the beginning of the 20th century, these views fell out of favor as scientists presented an increasingly complex world view. In response, philosophers turned away from metaphysical justifications for Ockham's Razor to epistemological ones including inductive, pragmatic, likelihood and probabilistic justifications, which is where things stand today. Thus, Ockham's Razor is accurately conceived of as a methodological principle not as a conclusive one, which is the substantive implication of the idea expressed in your response to my post.
A little bit of knowledge is a dangerous thing.
