Another key assumption is the authenticity of goodness and excellence, which asserts that positive traits like happiness, kindness and optimism are just as real and important in negative states like anxiety or depression. Seligman (2002) criticises traditional psychology for focusing too much on pathology, neglecting the study of what makes life worth living. Positive psychology suggests we all have signature strengths, such as humour or generosity, which can be nurtured to improve well-being. Therapies based on this assumption, like positive psychology interventions, aim to help individuals build on their strengths rather than simply treat their problems. This helps people develop resilience and prevent future mental illness, promoting a more balanced and empowering view of human potential.
