I agree but let me just give it a go by trying out these methods on myself because for all we know there could be some truth somewhere in all of this. Although the claim in the book of 'We think it is the only thing you need to know' scares me straight away and I see no signs that they have conducted studies except for looking at famous peoples photographs.
Ok when I look at the conceiving versus perceiving diagram on pg 53 it is clear that I have a conceiving type head setting.
How to Find Yourself and Your Best ... - Google Books
So I will lock in XXXj. That was easy!
Next intellectual versus emotional. The book claims that intellectuals have a flat, relatively large and expressive forehead when compared to the lower part of the face.Whilst emotional people's foreheads are small and less expressive when compared to the lower part of the face which shows expressions.
This seems to not support what I have previously learnt in the past which is that it is extroverted types which have more expressive foreheads and introverts who have less expressive foreheads.
This is one site that I have looked at in the past to see if visual identification could be applied very well in Socionics. Unfortunately it doesn't seem to be working properly at present as all of the sketches are not being displayed.
Google Translate
Just double checked that link and it's not working as it only takes you to the home page. Unfortunately it looks like you have to become a member before you can see the visual information now.
Also how does one type all of the more unusual foreheads like ones that slope back a lot etc by Rod's method?
So what forehead type do I have? Well clearly it's the small less expressive emotional one according to Rod's book.
So I now lock in XFXj.
Now apparently the eyes can give away if you are using

Extraverted intuition eyes

Do I have those? They are according to the book piercing eyes. I do not feel that I have piercing eyes but yes I do stare at one spot. But it says stares with eyes and mouth (am not sure if my mouth stares, lol). Yes I can see peoples 'cores' and yes I always have problems memorizing word for word.
Introverted intuition eyes

Are those my eyes? These are wide absent eyes, not pausing on any material objects. They give the impression of not seeing at all. Are my eyes like that? Well maybe they look that way, I often find myself just staring unfocusedly. If those are my eyes then I should be able to easily tell you what a certain character trait will evolve into after 30 or so years ( that's a mighty long time, I could tell you what it would evolve into in say 5).
Extroverted sensing eyes

Am I using this type? Apparently these eyes move a bit. In fact they are called running eyes! They examine people head to toe not missing a single detail and they can recall these details even on the deathbed-scary! They also remember long passages of verbatim. Oh this one is so not me

.
Introverted sensing

Are my eyes using this? These are slow moving floating eyes.They look like they are scanning the background and are good at perceiving the relationship between objects rather than objects themselves. You could say that my eyes are slow moving but I fail miserably at percieving the relationship between objects as I often bump, bang and trip into things. So no.
I will lock in

and

eyes which overall gives me intuition eyes to lock in.
So now I have XNFj.
Now am I introverted looking or extroverted looking? According to the book introverts are preoccupied with the internal processes which is reflected on their faces. They are often caught looking inside themselves or having an absent look. Yes I agree that I look like that.
Extroverts are dissociated from their inner world to a greater degree than introverts and display tenser faces. Their face reflects what is occurring around them which includes nothing if nothing is occurring. When they look at something their faces often seem passionate and engaged.
Well I don't think that is me at all but it doesn't mean that I don't ever have passionate and engaging moments.
So I am now locking in INFj.
Yes that's what I think I am...
