Culturally the success of an Igbo man is generally seen in the context of his "chi" and in the broader concept of the "ikenga". But t to understand the physiological and psychological attributes of the Igbo specie, authors like Hyacinth Ugwu Ezema, have dug deep.
In his controversial 'Origin of the Igbos' published by Great AP Express Publishers Ltd ( Nsukka) in 2011, the author through ecclesiastical and historical standpoints linked the genealogy of the ethnic Igbos to the Jewish race in Israel. He wrote, inter alia, "the overwhelming evidence of Igbo-Hebrew origin is no more in doubt, as this work has been able to highlight in terms of artifacts, culture, inherited traditions and norms of the people. It couldn't be farfetched, by extrapolation, to see that part of the Igbo civilization that came from the surmised Jewish ancestry, is an innate propensity to excel and dominate in a chosen field in or outside their homeland no matter the odds.
