The most damaging cognitive bias is overconfidence (illusory superiority), making leaders use their “gut” when they should be more rational.

Many of the cataclysmic leadership failures were failures of rationality. The pendulum of leadership development needs to swing back toward the rational: strategy, creativity, foresight, decision-making, and analytics.

21st century leaders will be growers, not knowers.

There was nothing scientific about Scientific Management (Taylorism), and neither was it good management.

Leaders need to sacrifice "power-over" to get "power-to".

Don't let Deepak Chopra manage your change program.
