well known in academia for developing and advocating for innovative measures or scales (e.g., survey instruments) that are sensitive to cultural and ethnic differences to ensure that any research conducted or treatment initiatives are valid, appropriate, and inclusive. He is co-developer of the Quick Discrimination Index, the Teacher Multicultural Attitude Survey, the Multicultural Counseling Knowledge and Awareness Scale, and most recently, the Multicultural Personality Inventory. These measures are used worldwide. Ponterotto is the co-author and or co-editor of 13 educational books. Ponterotto is also the author of a psychobiography (his first) on Bobby Fischer, titled A Psychobiography of Bobby Fisher: Understanding the Genius, Mystery, and Psychological Decline of a World Chess Champion. Being an avid chess player himself, Ponterotto decided to perform a detailed psychological evaluation on the trajectory of Bobby Fischer's life from his fame as a chess grandmaster at 15, which turned him into an international star and his being recognized as a prodigal genius, to his pitfalls and bizarre behaviors over time that ultimately led to his exile and death. His 2012 book is based on four years of research that included interviews with surviving family members, friends, chess masters, journalists, and biographers who knew Fischer as well as reviews of archives and available, FBI files related to the Fischer family. Based on the piecing together this agglomerated data, he was able to draw major conclusions that highlight Fischer's extraordinary intelligence and mental health challenges. Ponterotto's psychobiography notably grabbed the attention of the producers of the 2015 major motion picture Pawn Sacrifice, for which he served as a historical consultant.
