From Psychologists

They vindicate my long-held opinion that the instrument has solid statistical merit, and an underlying robustness that compares very favourably with similar systems.

 “Having used the Insights Discovery Preference Evaluator extensively in workshops, research and client work at the University of Dundee, I read the recent publication by the University of Westminster on the psychometric properties of the Insights Discovery Model with great interest.  In presenting a thoughtful, in-depth and clear analysis, the authors have provided a persuasive argument for pursuing typological research with confidence.  They vindicate my long-held opinion that the instrument has solid statistical merit, and an underlying robustness that compares very favourably with similar systems”

If one was ever skittish about pressing questions of the reliability and validity of the Insights Discovery Preference Evaluator, one can now move onto other concerns.

“The integrity of the Insights Discovery Preference Evaluator (IDPE) rests solely upon its thorough and rigorous measures of validity/reliability and its congruence with the colour scores measuring personality preference that embody Jung’s concept of opposites.  Instruments similar to IDPE have come and gone as each fails to meet one or more of these vigorous measures.  Only the best survive.  This present landmark effort assures the entire professional community of researchers, developers, practitioners and consumers alike, that their belief in the integrity in the IDPE is well placed and positively confirmed.  If one was ever skittish about pressing questions of the reliability and validity of the IDPE, one can now move onto other concerns”
