The ODC® assessment tool from Odin Company has a number of clearly distinguishing advantages :
The ODC is unique because it taps into the unconscious to reveal the true self – rather than being limited by conscious self-reporting and language interpretation as in traditional questionnaires. 
It achieves this through the use of archetypal images, asking the respondent which images they are naturally drawn towards or away from. This transcends culture, age, language and ethnicity because these archetypes are inherently understood – as Carl Jung discovered when he developed the model of archetypes in personality in the early 1900s. After eight years of intensive research and the results of thousands of people completing the ODC, it has been adopted by forward thinking organisations across the world.
