The predictive validity of the South African version of the Giotto:
Nedbank commissioned research in which the predictive validity of the South African version of the Giotto was investigated as well as the extent to which it might display unfair bias among gender, age, educational and race groups. The research was conducted by Professor Karl F. Mauer with the following important findings:
- The predictive accuracy of the South African version of the Giotto is 94%.
- The Giotto can be used with a considerable degree of confidence in identifying job applicants with a risk profile as far as the likelihood of becoming involved in economic crimes and unethical behaviour is concerned.
- It shows no bias towards race, age, gender and level of education variables.
- The Giotto would stand up in labour court if the necessary legal requirements of fairness were adhered to.
- It is advised to use additional instruments of profiling for example record checking, as no procedure exists by which it is possible to predict human behaviour with perfect accuracy.
