Perhaps you share a DISC style with one of the famous leaders profiled here!
Nelson Mandela, Reformer DISC Style
Nelson Mandela was a noted human rights activist who led South Africa's fight against segregation and apartheid. Over the course of his life, Mandela received more than 250 honors, including the Nobel Peace Prize in 1993.
Mandela’s DISC style was likely Reformer, or a combination of the styles IDS. As leaders, Reformers desire to remain constantly involved in building relationships and being at the forefront of new projects. Reformers are passionate, expressive, and responsive people who love to communicate their thoughts and opinions to others who are truly concerned.
Mandela’s Reformer style was evident in his resilience and ability to inspire others even during 27 years in prison. Reformers are natural visionaries who see what could be and work tirelessly to bring about change. For Mandela, this meant using both charisma and conviction to dismantle apartheid and unite a deeply divided nation. Reformers thrive in roles where they can challenge injustice, spark innovation, and encourage people to believe in something greater than themselves.
Mahatma Gandhi, Attainer DISC Style
Mohandas Karamchand Gandhi led the fight for Indian nationalism in the 1920s. "Mahatma," which translates to "venerable" in Sanskrit, was an honorific first bestowed on him in 1914 in South Africa, and is now widely used. His approach of nonviolent protest inspired similar movements in support of rights and freedoms around the globe.
Gandhi’s DISC style was that of an Attainer, or a combination of D and S styles. Attainers are practical people who evaluate themselves and others by results. Under pressure for these results, they may be direct and have a "no-nonsense" approach. They like to finish what they start and do it thoroughly.
Attainers are goal-driven leaders who balance discipline with determination. Gandhi’s ability to stay calm under immense political pressure and his insistence on seeing goals through to completion made him an enduring example of an Attainer in action.
Martin Luther King Jr., Chancellor DISC Style
Martin Luther King, Jr. was an American activist and humanitarian who became the leader of the Civil Rights Movement. Similar to Gandhi, King became known for advancing civil rights through nonviolent civil disobedience. In 1964, King received the Nobel Peace Prize. He was also awarded the Presidential Medal of Freedom and the Congressional Gold Medal posthumously.
King’s DISC style was likely Chancellor, or a blend of D, I, and C styles. Chancellors are extremely efficient and action oriented. They tend to like a faster pace with more action and less talk. King’s Chancellor style was evident in his ability to mobilize people quickly, articulate a clear vision, and push forward with urgency despite overwhelming opposition.
King’s famous “I Have a Dream” speech demonstrates the Chancellor’s gift for combining inspiration with practical calls to action. Chancellors are decisive and persuasive, which allowed King to unify communities and ignite a movement that transformed a nation.
Mother Teresa, Peacemaker DISC Style
Mother Teresa was an Albanian-born Roman Catholic nun. In 1950, she founded the Missionaries of Charity in Calcutta, India, a religious congregation that is currently active in more than 130 countries. She was awarded the Nobel Peace Prize in 1979. In 2016, she was canonized by Pope Francis and given the title Saint Teresa of Calcutta.
Mother Teresa’s DISC style was likely the Peacemaker, combining S and C styles. Peacemakers place a high importance on accuracy and precision, and desire to have quality be their hallmark. Peacemakers have no problem making a decision, but prefer to have exact facts and figures initially.
Mother Teresa’s Peacemaker style came through in her quiet strength and steady commitment to serving the poor. Peacemakers are dependable, empathetic, and highly relational leaders who value harmony and seek to make the world a kinder place. While not driven by fame or recognition, Peacemakers influence others through their consistency and selflessness. Mother Teresa’s leadership reminds us that peacemaking often has a ripple effect, inspiring countless others to act with compassion.
Stephen Hawking, Assessor DISC Style
As an author, Stephen Hawking was known for his best seller A Brief History of Time, but he was also an English theoretical physicist, cosmologist, and Director of Research at the Centre for Theoretical Cosmology within the University of Cambridge. His books helped to make science accessible to everyone.
Hawking’s DISC style was that of an Assessor, or CI combination. Since Assessors are equally driven by social relationships and completing tasks thoroughly, they constantly evaluate which takes precedence so they can allocate their time accordingly. They can be counted on to do a good job and pay attention to detail, while being aware of the needs of the people around them.
Hawking exemplified the Assessor’s determination to work carefully and deliberately while remaining attuned to the importance of sharing knowledge widely. His calm, methodical leadership style not only advanced science but also inspired others to think more deeply about humanity’s place in the universe.
