Title: Can Finger Length and Height be an Indicator of One
1Can Finger Length and Height be an Indicator of
Ones Aggressive Personality?
- By Nusrat Chowdhury

2Introduction
- Aggression has been a difficult term to provide
one concise definition of because it encompasses
many different types of behavior, some of which
are not clearly related to each other. - Wikipedia Encyclopedia defines aggression as an
act of initiating hostilities or invasion. It can
also be described as practice or habit of
launching attacks, or being hostile (Aggression
n.d.).
3Introduction
- Moreover, it has been known for more than a
century that the length of the index finger
relative to the ring finger differs between men
and women. (Finger length predicts Aggression in
Men, 2005). - In women, the index and ring finger are roughly
equal in length. But in most men, the ring finger
is longer (Finger Length n.d). This is a result
of fetal exposure to testosterone.
4Introduction (cont.)
- More recently however, researchers have found a
direct correlation between finger length and the
amount of testosterone that a fetus is exposed to
in the womb. - The shorter the index finger is in relation to
the ring finger, the higher the amount of
testosterone the man was exposed to in the womb
(Katherine, 2001) .
5Introduction
- Furthermore as this new research shows, the
shorter the index finger, the more likely he is
to be physically aggressive throughout his life(
Bailey et al, 2004).
6Purpose of Study
- Although, they have found a strong relation
between the ring finger and aggression, it is
still a mystery whether this conclusion implies
an individuals height as well. - Since the previous research has showed
correlation between finger length and aggressive
personality, it is possible that peoples height
can also tell us something about their
personality. - Therefore, the purpose of this study is to
determine if along with finger length, whether
ones height can also be an indicator of his/her
aggressive personality.
7Materials and Methods
- The experiment will be conducted in New York
City. All participants will be presented with an
informed/parental consent form (Figure 1). The
participant will be asked to complete an
aggression questionnaire (Figure 2). - The aggression questionnaire consists of four
subscales hostility (eight questions), anger
(seven questions), verbal aggression (five
questions) and physical aggression (nine
questions). - The test will use a one (extremely
uncharacteristic of me) to five (extremely
characteristic of me) Likert scale.

- Introduction
- I have been asked to participate in a research
study conducted by Nusrat Chowdhury, a student at
H.P.H.S. This research entitled Can finger
length and height determine an individuals
aggressive personality? This experiment is
designed to determine weather any correlation
exists between individuals height, finger
length, and their aggressive personality. The
participants will complete an aggression
questionnaire. The survey is composed questions
that will evaluate individuals aggressive
personality and it will be compared with their
height and finger length. This will help the
principal investigator to determine whether there
are any correlations between a persons height,
finger length and their aggressive personality. - Plan and Procedure
- Parental informed consent forms will be
distributed to high school students in grades
9-12 and adults who are over 18. The surveys will
be collected at the time of completion and the
principal investigator will analyze the results.
9Parental Consent (cont.)
- Risks
- There are no potential risks or discomfort in
this procedure. - Potential Benefits
- This research project will help us to understand
whether any correlation exist between a persons
height, their finger length and aggressive
personality. Previous studies have shown some
correlation between finger length and aggressive
personality. Thus, if any correlation is found
between height and aggressive personality, then
it will proved that not only finger length but a
persons height can also predict whether a person
is prone to aggression or not. - Confidentiality
- All the surveys will be kept confidential. No
personal information such as name, age etc will
be seen by anyone other than the principal
investigator and mentor. - Voluntary Participation
- It is understood that participation in this
study is voluntary. Refusal to participate - will involve no penalty or loss of benefits to
which anyone is otherwise entitled. Furthermore,
anyone may stop participating at any time they
choose, without penalty or loss of benefits.
10Parental Consent (cont.)
- Consent to Participate
- I certify that I have read all of the above,
asked questions and received answers - concerning areas I did not understand, and have
received satisfactory answers to these questions.
I willingly give my consent for participation in
this research study. (A copy of this consent form
will be given to the person signing as the
subject or as the subject's authorized
representative.) - Participant's name (print)

18Figure 1 Finger Length and Height
This comparison showed no significant result or
link between a persons height, and their finger
length.
19Figure3 Correlation between index finger and
Aggressive personality
- However, as previously, acknowledged, that there
is a significant relationship between a persons
physical aggression and finger length (Figure 3).
- The shorter ones index finger is, the more
aggressive he tends to be.
20Discussion
- From my experiment I have found out that my
results correlated with the previous studies that
have been conducted before. There was a
correlation between mens index finger and their
aggressive personality - The shorter the index finger is, the more
physically aggressive a man tend to be. - From this trend it can be assumed that prenatal
testosterone has a stronger effect on the trait
of physical aggression than do adult testosterone
levels. - No correlation was found between a persons
height and their aggressive personality. It is
because an individuals finger length is
determined by the exposure of the sex hormones
while height is not. Therefore, it can be
concluded testosterone plays a greater role in
determining a mans masculinity than playing a
significant role in determining ones height.
21Conclusion
- From my experiment it was concluded while finger
length can tell us something about ones
aggressive personality, height can not. - The shorter an individuals index finger is the
more physically aggressive they tended to be.
