Final answer:
Self-awareness is the leadership development technique that can help identify blind spots.
Step-by-step explanation:
The leadership development technique that can help identify "blind spots" an individual may be unaware of is self-awareness. Self-awareness involves gaining a deep understanding of oneself, including personal characteristics, strengths, weaknesses, biases, and beliefs. It helps individuals identify areas for improvement and recognize their blind spots, which are aspects of themselves that they may be unaware of or do not see clearly. By increasing self-awareness, individuals can better understand how their actions and behaviors impact others and become more effective leaders.
