Aspies For Freedom

To me, he looks like a Russian Tom Selleck...

The only Autistic-ish aspect to the photo is that he isn't looking at the camera... but then lots of NTs don't do that either... and a lot of Autistics look straight at the camera.

Naw, really?  Do some of 'em even grin while doing it.

Won't work.  The shape will still be preserved.  We are not dealing with physical matter but shapes "in and of themselves", divorced from the properties of matter.

Yes. Look at my Avatar.

Some even have a slight dimple in their chin when smiling.

Check out the Autistic Adults Picture project for a collection of both straight-lookers and averters when photographed.

Smilers and non smilers there also... and even a few who show their teeth to varying extents.

One can theorise about somebody posthumously, but one CANNOT diagnose a condition such as Asperger's Syndrome posthumously.

I think it's possible, given the right abundance of sources.  One can certainly identify autistic traits in a person, although separating them from legend gets much harder the farther into the past one goes.  It all depends on what's available.  Can Einstein be given an accurate diagnosis?  I think so.  Neuton?  Maybe, maybe not.  The time frame makes it iffy.  I definitely wouldn't trust van Gogh, or indeed anyone with limited information on their childhood development.  

But I wouldn't say it was impossible just because the person happened to die before the right piece of paper was slapped on.

I would be interested also.
