This chapter focuses on the concept of practical intelligence, which reflects a broader conceptualization of the abilities needed for real-world success. It reviews research on tacit knowledge as an aspect of practical intelligence and consider the implications that practical intelligence has for work psychology. The concept of intelligence traditionally has been viewed as integral to successful performance because it represents the ability to adapt effectively to the environment and to learn from experience. g is the most widely studied and validated predictor of performance in employment and educational settings. Practical intelligence encompasses the abilities one needs to succeed in everyday life, including in one's job or one's career.
