After various digit ratio studies found conflicting results related to Extraversion & sensation seeking (most pointed into the direction of a negative correlation), a new Dutch 2012 study suggest that other finger lengths require to be taken into account in order to find more clear results!
The (unpublished) results from a female only suggest that low 2D:4D digit ratio + long pinky finger are much more often found in the hands of ‘extroverts’ (8 out of 40 hands = 20%), while this combination is rarely seen in the hands of ‘introverts (0 out of 28 hands = 0%).
Additionally, a high 2D:4D digit ratio with short pinky finger is much more common in the hands of ‘introverts’ (5 out 28 hands = 18%), compared to the hands of ‘extroverts’ (3 out of 40 hands = 7.5%).

|The little finger (your ‘pinky’ or ‘pinkie’) relates to autism:
What do we know about the ‘pinky’ or ‘pinkie’? In the past certain features of the little finger have been related to autism & various medical syndromes. New research from The Netherlands indicates that a ‘curved’ pinky is often found in the hands of people who have autism.
Psychiatry researcher Ozgen from University Medical Center in Utrecht (The Netherlands), presents the details of the research in the journal ‘Molecular Psychiatry’.
|“The presence of small physical defects and the occurrence of autism often go together”, says Dutch researcher Ozgen. Some of the physical defects reported are:
These are subtle physical defects without a specific medical significance, and cosmetic surgery is usually not necessary when these body features are present.
NOTICE: Ozgen noticed in her studies that these physical defects more often occure in patients with autistic disorders, compared to the healthy controls.
DIGIT RATIO & AUTISM:
Likely, one can understand the findings of Ozgen a little bit more in perspective of the FINGER RATIO (2D: 4D digit ratio) evidence presented by UK psychologist John T. Manning.
Manning describes in his first book DIGIT RATIO that autism is frequently featured with a ‘low 2D:4D digit ratio’ [= the ratio between the full length of the index finger (= 2th finger) & the full length of the ring finger (= 4th finger)].
