ABSTRACT
Introduction We have seen in Chapter 4 how there is now quite good agreement between theorists about two of the main personality factors (extraversion and neuroticism) – few would now disagree that these are the two main personality traits. However, merely establishing the structure of personality is only the first step in any scientific study of individual differences. Doctors have known a lot about the structure of the human body (the location of the main organs) for millennia, but it is only fairly recently that medical science has begun to understand how the organs operate and interact. So it is with personality. The main dimensions having been identified, the really interesting questions involve trying to understand:
● what causes certain behaviours to vary together to form these traits
● what causes an individual to develop a particular personality.
