Research & Validity

Research and Validation Resources

Almost two million people have completed the Kolbe Indexes on six continents. Respondents have ranged from 4 to 88 years old and include a wide range of ethnic, racial and socio-economic backgrounds, all job classifications.

With data from business, government, education, high-tech and manufacturing industries, the Kolbe Concept® has been thoroughly researched, validated and refined into a practical system for personal and group development.


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. Conative Tests evaluate the instinctive talents you were born with — the way you take action. Cognitive Tests evaluate intelligence and what you’ve learned; i.e. your knowledge and skills. Personality Tests evaluate your affective “style,” your preferences and how you feel.
