Three Parts of the Mind

Ancient philosophers and modern psychologists share the concept of a three-part mind with separate domains for thinking, feeling, and doing. The conative, or doing, part contains the striving instincts that drive a person's natural way of taking action, or modus operandi (M.O.). This is the unique set of innate strengths and talents every person has which remains unchanged from birth. Everyone has an equal amount of conative energy for engaging the thinking (cognitive) and feeling (affective) parts of the mind to produce purposeful action.      


How are Kolbe Indexes Different from Other Assessments?

Mental assessments look at different parts of the human mind. The Kolbe A™ Index is different because it is the only validated assessment of the conative part of the mind.


Cognitive Tests

like the SAT or Wonderlic Cognitive Ability Test evaluate intelligence and what you’ve learned; i.e. your knowledge and skills – identifying what you KNOW.

Personality Tests


like Myers Briggs Type Indicator ® , Predictive Index ® and DiSC evaluate your affective “style”, your preferences – identifying how you FEEL and what interests you.

Conative Tests

The Kolbe Indexes are the only tests that look at conation, evaluating the instinctive talents you were born with – identifying the way you take ACTION.
