Abstract: The paper looks into regularities in the history of psychology as a science and as a profession that may stand generalization beyond conditions and contexts. Lacking a better term they are referred to as “lessons” to be deduced from history. As to the first, the history of psychology as a science, six such regularities are proposed: (i) dual status of psychology as a scientific discipline and a “bridge” science due, integrating biological, social and cultural methods; (ii) indispensability of empiricism as methodological guideline; (iii) cross-over utility of results from basic and applied research; (iv) need of alternative heuristic scales; (v) compatibility of universality and indigenization; and (vi) disciplinary strength of psychology in scientific development. Another additional 3 regularities are proposed from a examination of psychology’s history as a profession: (i) rapidity of professionalization; (ii) need of two-way transfer between academia and practice; and (iii) lessons to be learned from cross-disciplinary give and take of expertise

Key words: psychology, history, lesson
