Our Method: Immunity to Change

Where did this idea come from?

  • The Immunity to Change (ITC) theory comes from the research of Robert (Bob) Kegan and Lisa Lahey, professors at Harvard University, who discovered through years of research why we have such a difficult time with change. 
  • Just as our bodies have a physical immune system that protects us from the bad stuff in the world, we also have a psychological immune system that works to protect us from harm, yet at the same time, it may keep us from moving forward on positive changes, too!

How does this idea show up in my life?

  • It feels like you have one foot on the gas, trying to move forward to reach a positive goal in your personal or professional life, but at the same time, your other foot is on the brake, keeping you from moving forward.
  • We help you identify and then coach you to release your behaviors, beliefs and assumptions (the foot on the brake) that are holding your back from making that change or reaching that goal.
  • You may feel conflicted in your personal development because of what we call “competing commitments.” We coach you through these challenges to reach your personal and professional goals.

How do we use the ITC theory?

  • Gary, Connie, and Tom are all certified ITC coaches.
  • We use the ITC theory as the basis of our Coaching, our Developmental Dash and for the Team Development Challenge.
  • Our Entrepreneurial Leadership program combines ITC coaching with business training to fully invest in the success of our entrepreneurs in the developing world.
Below is a great presentation by Bob Kegan on his theory!
