This is a bit of a tangent but I think we can all agree that with the absolute glut of endless streams of information we are now relying more and more on heuristics to determine what information is relevant than we've ever done.

Yet people still go on about never judging books by their titles and all that jazz.

Is it finally acceptable to use appearances as a heuristic albeit an imprecise one and to expect people to put some effort into their appearance in aid of this?

I mean as valuable as every potential colleague, aquaintance, or other professional contact is I don't have the ability or the wherewithal to get to know everyone I meet on a fundamental level without any external manifestation of their inner nature.

Is there a balance between click bait and utterly banal that we can apply to articles, and people too?
