I tried this a long time ago, when I was first learning socionics, and when Galen and thehotelambush posted their versions, I thought I'd try my hand at it again.
Each face is a mashup of four photos, either of people I know or celebrities I feel confident I have typed correctly. Being the occasionally obsessive perfectionist that I am, I used morphing software and morphed the faces together by hand. I'm quite happy with the results, and they seem fairly readily identifiable as their types, to me.
Can you guess their types?
Male A
Male B
Male C
Female D
I hope to continue doing these as time allows. I don't have enough really reliable examples to do a male and female version of each type, but I'll see what I can do.
