Practical intelligence, according to Sternberg, encompasses the ability to navigate social interactions effectively. This includes understanding the dynamics of communication, such as what to say to different individuals, when to address certain topics, and the manner in which to express one's thoughts for the greatest impact. These skills are crucial in achieving success in various situations, as they enhance interpersonal relationships and facilitate effective collaboration.

This concept highlights that success is not solely determined by academic intelligence or technical skills, but rather by one's capacity to apply knowledge in real-world contexts. By mastering practical intelligence, individuals can leverage their social skills to create opportunities and influence outcomes, underscoring its importance in both personal and professional spheres.
