Literature relating to personality and entrepreneurship has focused primarily on personality characteristics of traditional entrepreneurs. The focus of this study was on personality characteristics and temperaments of potential Information and Communication Technology (ICT) entrepreneurs. The main objective of the study was to evaluate the efficacy of personality characteristics as identifiers of potential ICT entrepreneurship. The personality characteristics of the participants were measured on the Keirsey Temperament Sorter, a proven research instrument. Two entrepreneurial tests were used to determine entrepreneurial ability. The temperament of the individuals was ascertained and compared to their entrepreneurial ability. The population sample used for this study was comprised of third year and honours information systems students from the University of Cape Town and current ICT entrepreneurs. A positive relationship between the rational and idealist temperaments and potential ICT entrepreneurs was found. No significant relationship between specific personality types and potential entrepreneurial ability were evident in the study. A positive connection was noticed between potential ICT entrepreneurs and being male. Unfortunately the number of female respondents was insufficient to lead to a conclusive result.
