The Herrmann Brain Dominance Instrument (HBDI) is a 116-question, highly validated diagnostic survey. Your answers indicate your thinking style preferences. Scoring results are free from value, judgement and cultural bias. The HBDI Profile is available in a variety of formats: The paper package includes a full colour profile, an accompanying interpretation booklet that explains the profile and scores in detail, and a discussion of the implications your results have for business and personal life. The online version, via the Thinker Portal, provides all of the same information in an accessible online format and includes additional learning information, such as how your thinking shifts under stress and applications of the concepts to teaming, communications and innovation. The HBDI App for iOS and Android gives you quick, easy access to your HBDI results anywhere, anytime, to reinforce and continue the learning and application process.
