The growing attention to teachers` emotion has been in line with the new necessities of modern life and has been considered as a leading exponent of fast-changing educational settings through the clarification of the new personal accountabilities. This unique study endeavored to compare levels of anxiety, depression, life satisfaction, job satisfaction and life pleasure between teachers in humanities, formal sciences and natural sciences. More than 720 teachers across 14 different academic disciplines were compared and contrasted based upon the result of the following standard psychological tests: Snaith-Hamilton Pleasure Scale, Beck Anxiety Inventory, Diener`s Satisfaction with Life Scale, Brayfield-Rothe Index of Job Satisfaction and Goldberg Depression Scale. The results were enlightening as the humanist teachers` psychological well-being was conspicuously superior to their counterparts in natural and formal sciences. Being that said, the result can broaden the horizon of educational researchers whose work revolves around emotionality of teachers as well as educational planners and programmers to consider the implications in their teacher training programs.
