What aspect of a leader’s intellect involves understanding and working with others' social cues?

The correct choice is interpersonal tact, which refers to a leader's ability to perceive, interpret, and respond appropriately to social cues exhibited by others. This skill is essential in creating a collaborative environment, as it involves recognizing emotions, body language, and verbal tones that others display. A leader with strong interpersonal tact can effectively navigate social dynamics, foster relationships, and manage group interactions in a way that promotes trust and open communication.

Interpersonal tact is crucial for building rapport and understanding the needs and perspectives of team members, which ultimately leads to more effective collaboration and conflict resolution. This understanding helps leaders to motivate, inspire, and engage their teams more effectively.

Other options, such as innovation, sound judgment, and mental agility, while important aspects of leadership, do not specifically focus on this social understanding. Innovation pertains to creativity and generating new ideas, sound judgment relates to making wise decisions based on experience and knowledge, and mental agility involves adapting to new information and changing circumstances. None of these emphasize the nuanced understanding of social interactions that interpersonal tact does.
