Definitely not one dimensional. There's the subconscious 'pattern recognition hardware' from our brain regarding holistic similarity which is a balancing act of tolerance for differences based upon how much interpretation is necessary to make sense of the print. In addition though, other psychological dimensions such as affiliation (will my verifier agree?), the confirmation of internalized norms (am I following the SOP/Office culture?), the need for safety (am I making a risky decision? What happens if I'm wrong) and more cognitive dimensions like competence(am I able to come up with the right answer?) or meta cognitive dimensions (how will I explain what I did if this case goes to court?)

Obviously these psychological components vary with the level of complexity present in a comparison

It seems that our friends in the print world are catching up to the conversation. In a new paper titled 'Vacuous Standards', the authors put forth a not so novel concept. Namely that the OSAC Standards are too vague to be practical or testable in a way that allows them to be validated as scientific.

I am almost probably certain that there's strong support that we disagree on how to resolve the issue. (see what I did there). However, it seems these circumstances have made strange bedfellows out of the community at large.

Thoughts on the article?
