Theoretical explanations suggest that insight might increase life satisfaction by helping individuals choose a suitable academic major, indicating that insight might facilitate life satisfaction through academic major satisfaction. The current study thus investigates the mediating role of academic major satisfaction in the potential relationship between insight and life satisfaction. The data collected from a sample of 206 undergraduate students majoring in education degree programs confirm that the relationship between insight and life satisfaction is fully mediated by academic major satisfaction, with a model explaining 23% of the total variance in life satisfaction. The findings have important implications for the design and implementation of career counselling and guidance services provided within high school and university settings, particularly in countries such as Turkey where career counselling services need improvement.
