This is my first post here, pardon any clumsiness.
So I've always noticed similarities between people since I was a kid, resemblances and 'types' that I'd point out and people are like, "You need to get your eyes checked." In the past year, between getting obsessive with MBTI and spending a lot of time browsing http://www.celebritytypes.com, it all started to click.
I've been taking the images from from their site and arranging them according to sub-types within the MBTI matrix. It's mostly visually, but also intuitive and based on what they do. To me the pattern just leaps out... to the site's owners and others I've showed it to, not so much :[ So I'm gonna try to throw some of the images up here and see if anyone else sees it.
To answer, BTW, "are you just typing serious lookers with serious lookers, small chins w/ small chins, etc?"... yeah, all valid questions, needs double-blind, etc. But if you're seeing the patterns I'm seeing, you'll notice a huge differences between like the ESTP groups and the INTJ groups.
p.s. I've added notes in the images for other interested parties, and images of typed friends, if you're like "wha... who?" Them's my scribbles!
