On the other hand, the nomothetic approach to personality looks at the indivuals and the similarities that they have between them. It is assumed that personality traits that are studied have the same psychological effect for everyone. One nomothetic approach to psychology is the trait theory. This looks at how a dimension of personality can be used to categorise different indivuals using their different characteristics otherwise known as traits.
