Introduction: The concept of Prakruti is a unique contribution of Ayurveda. Ayurveda lays great emphasis on the examination of Prakruti which is the natural state of an individual. This is very important because only by understanding the original state of the body function one can understand the possible derangement in the functioning. The primary aim of Ayurveda is also to maintain health in healthy person and hence knowledge of Prakruti is imperative. It is the enumerations of body features internal as well as external. Intelligence is the aggregate or global capacity of the individual to act purposefully, to think rationally and to deal effectively with his environment (Wechsler, 1944, p.3). A universally accepted uniform definition of intelligence has yet not evolved by the psychologists. The intelligence quotient is the ratio of individuals’ mental age to his or her chronological age. An individual’s I.Q. indicates the rate of mental development or the degree of brightness. If the mental development keeps pace with one’s life age, the quotient is 100.
Problem Statement: As individuals of different Prakruti are described to have different prototypes of Jnana, they are expected to have different intelligence and vice-versa. Intellectual errors (Prajnaparadha) lead to causation of all diseases. By avoiding intellectual errors one can be free from onslaught of diseases.  Longevity without intelligence is a burden not only for a humanbeing but also to the society. Assessment of intelligence and its promotion thus becomes a need of the era. Considering all these points, this study is a proposal to be conducted on healthy volunteers of different DehaPrakruti to observe the influence of Prakruti on Intelligence Quotient and its comparison among them.
Objective: To assess the interrelationship between Intelligence Quotient and Dosha Pradhana Deha Prakruti in apparently healthy individuals.
Hypothesis:
Alternate Hypothesis: There is a relation between Intelligence Quotient and Deha Prakruti.
Null Hypothesis: There is no relation between Intelligence Quotient and Deha Prakruti.
Assessment Criteria:
Deha Prakruti Assessment: Dr.Kishore Patwardhan’s Standard Prakruti Assessment Questionnaire Format will be used without any modification.
Intelligence Quotient Assessment: Wechsler’s Adult Intelligence Scale will be adopted without any modification for the assessment of Intelligence Quotient.
Subjective Parameters:
Individual Prakruti

Objective Parameters:
Intelligence Quotient
