So, this leads me to my second point: genetics influence facial features, but not necessarily Socionics type. Typing someone on how their face looks – and I do not mean facial expression (those facial composites all have about the same facial expression, btw), but things like eye or nose shape etc. – is greatly misleading. (Besides, I have got a very similar face shape to my SEE sister. Again, types are not the same at all.) Socionics is about how a person functions, the type is mainly something that is based on the processes in the brain, though those processes will show themselves in someone's actions, ideals, goals, and the like. All of those aspects are not detectable in a motionless face.
At last, I believe those facial composites are inherently flawed due to the fact there must be many mistypes in them. (Socionics still does not have a good typing system; and based on my experience, many Socionists still mistype several people on a regular basis, especially celebrities or famous figures.)
All in all, just because someone looks a bit like a facial composite of a type (or not), does not mean they are that type (or not).
Though I'd like to add that even if you had the ability to type someone based on their face only, you'd have to recognize that Quasi-Identicals will have a very similar look, simply because their functional strengths are equal. So, in regards to differentiating LSI vs SLI, you'd most likely have a problem.
