Our personality is determined from a young age, and directs different styles of behavior throughout our lives in a variety of situation, starting from the playground as children, through school and college and onwards to our adult life as independent functioning people. As such, our personality plays a crucial role in our personal, interpersonal, social, and professional lives.
The biggest, most reliable and valid model for assessing an individual’s personality today is the Big-5 model. It has been studied over decades and across cultures by different sets of researchers. The predictive power of the Big-5 model is robust across life domains and especially in the field of job performance. It has higher validity and reliability than most well-known measures of personality (e.g. Mayers-Briggs) and it is being used all over the world both in academy and industry.
