Low 2D:4D finger ratio: a confirmed hand sign in Autism!

Hello Martijn,

This is right that differences in finger length ratio between males 'may' indicate autism, with spreading developmental disorder and anxiety disorders, but, this cannot be sure or confirmed hand sign for autism.

Researchers have also found that a longer ring finger makes a person attractive. If ring finger is longer than index finger will be smaller. I want to know how a person at a time can be attractive, vivid, shiny, promising and suffer from autism too? Yes, the hand would have to be analyzed in totality then.

But, we cannot say with surety that Children with autism have a relatively shorter index finger (2D) compared with their ring finger (4D) definitely. This will be IMPROPER and will create doubts in freshers. It will be PROPER to say that low 2D:4D ratio ‘MAY’ serve as one possible marker of autism.

This is clearly mentioned there at the link mentioned below. I KNOW MANY MANY PEOPLE WHO HAVE SHORT INDEX FINGER AND NOT SUFFERING FROM AUTISM AT ALL.

They say “It is often PRESUMED that the 2D:4D ratio is associated with fetal testosterone levels and that high fetal testosterone levels COULD play a role in the cause of the disease of autism. They also say that “It is unknown whether this effect is specific to autism.”

I think you will agree with me that this is not a confirmed hand sign of autism.

Dear Parender,

I only used the word 'confirmed' to highlighten the fact that many studies around the world have confirmed that a low 2D:4D digit ratio is usually found in autism.

Regarding your words:

"But, we cannot say with surety that Children with autism have a relatively shorter index finger (2D) compared with their ring finger (4D) definitely."

True!

However, your words appear to suggest that I made such claims by using the word 'confirmed', but now that I have explained why I used the word 'confirmed'... I can only hope that you will now recognize that you misinterpretated my use of the that word. Because, if you re-read my first post properly... you should notice that I never suggested that it is a 'sure' indicator for autism.

Does this make sense so far?


Then regarding your words:

"Researchers have also found that a longer ring finger makes a person attractive. If ring finger is longer than index finger will be smaller. I want to know how a person at a time can be attractive, vivid, shiny, promising and suffer from autism too? Yes, the hand would have to be analyzed in totality then."

True, that is a valid question!

The answer is that this can be understood by focussing on how the hormone 'testosterone' can manifest in various types of behavior... including various positive types of behavior (like for example: assertiveness & enthousiasm)... plus various less-positive types of behavior (like for example: autism & agression).

So, yes you are right again... one can not 'interpretate' any manifestation of the 2D:4D digit ratio without considering other aspects of the hand.

But the 2D:4D digit ratio is for sure a key-element in understanding how autism manifests via the hand - though (having said that) this does not implicates that all people with autistic spectrum disorders have a low 2D:4D digit ratio... but for sure: a large majority of them do have this hand characteristic.

Makes sense now...???



Anyway... Parender, thanks for responding + sharing your thoughts & questions!!

Is it attractiveness, based on sexual attraction or is it simply being an attractive person that you are referring to? The reason I ask is because I have found that the autistic people that I have met to be attractive in the sense that I look past their social faults to the pureness of their self. I find it completely refreshing to be around someone is isn't caught up in how they appear to others. Now, my experience with people with Autism has been with more of the functioning Autistic variety. Not everyone shares my views on this, maybe subconsciously they are attractive for being themselves.

Hello zeblethai,

They say the longer a man's fourth or ring finger is compared to his index finger, the more likely he is to be judged attractive by women, according to a new study.

But, I think an attractive person is first of all pleasing to the eyes or mind in first place through beauty or charm who has attractive personality.

For example you can say like attractive clothes or attractive book or book cover or attractive illustrations. Your job is attractive because of your pay. A person who has the properties of a magnet; can say who has the ability to draw or pull. Like me! Ha ha ha!
They say Men with higher testosterone tend to have deeper voices, more symmetrical faces, and ‘a distinct body odor who have longer Ring Finger. You can read full essay at:

And the link at the forum posted by me is:
https://www.modernhandreadingforum.com/t753-attractive-men-have-long-ring-fingers
And autism means (psychiatry) an abnormal absorption with the self; marked by communication disorders and short attention span and inability to treat others as people. This is quite contrary to attractiveness.

Obviously, you may be right in this regard because no sign on the palms of the hands is absolute in itself. It will depend on person particular.
Enjoy!
