I got 6 out of 10.
Ten out of ten. But that’s probably because I can recognize pictures of most 20th century serial killers.
What? I think it’s interesting …
5 out of 10… If I hadn’t recognized the one that is probably one of the more famous serial killers, I probably would have guessed he was a programmer, too.
9 outa ten… I even got Citizen X… Andrei Chikatilo
6 out of 10. I was proud I guessed the one who was both a programmer and a serial killer. Then again, I think everybody but me is a serial killer.
7 outta 10 for me
9 of 10. I missed on John Christie.
Atleast it wasn’t because you recognized the language pragrammers. That would be really weird.
Ditto. He looked so… respectable.
8 out of 10, and the only one I recognized on sight was David Berkowitz. I missed Anatoly Onoprienko (Russian serial killer) and Randy Kraft (serial killing computer programmer).
I pegged John Christie as a serial killer right away. Sure he looked respectable. That’s how I knew he wasn’t a computer programmer. 
That’s the only one I missed too. Strange…
8 out of 10. Mostly using my heuristic – computer programmer == shaggy-haired guy or, if b&w photo, looks like an IBM employee. My apologies to Griswold, the inventor of the very cool SNOBOL language.
Who’s to say that they can’t be both?
5 out of 10, and it would have been worst if I hadn’t recognized two of them (Christie and Berkowitz).
6 out of 10 but what was the point?
6 out of 10 and made me laugh quite a bit.
