Nigeria as a country is endowed with what is required to become one of the greatest countries of the world in terms of social, political, economic and educational development, but the menace of “Nigerian factor” has become one of the major impediments to the realization of that feat. The menace has become part of the socio-cultural pattern among Nigerians that it has become very difficult to uproot in spite of the anti-corruption war. Nigerian factor is a corrupt value system and mind-set that are learnt either consciously or unconsciously which propels an individual to seek for selfgratification against the collective interest and growth of the nation. It manifests in the attitude to work of Nigerians, expectation of gratification and appreciation before carrying out an official duty, “sorting” in educational institutions in order to gain undue advantage from lecturers, nepotism and cronyism, long leg, poor attitude to due process, bottom power, among others. Nigerian factor puts both private and public officers in a fix between doing the right thing or towing the line of the menace, it affects the quality of graduates from educational institutions, leads to marginalization of those that refuse to tow its line, and so on. The paper therefore recommends value reorientation through effective teaching of values in Social Studies at different levels of education, attitudinal change through the instrumentality of education, modelling of appropriate values and attitudes among others.
