Think you're right? How to test yourself in the battle of ideas.

Our opponents' objections to our ideas often contain insight as to how we can better refine them.

  • When we're convinced in the truth of our ideas, we often believe if we just explain it to others that others will immediately come onboard with them. However, what we see in practice is that we need some resistance from others to help refine those ideas. In doing so, we make them more marketable in the marketplace of ideas.
  • When we have debates, we have to not censor our opponents. We have to be confident enough to have discussions with them aimed at getting at the truth.
  • When we prohibit the expression of ideas, we lose the chance to prove our ideas right — we lose the chance to advance their legitimacy in the court of public opinion.

Want to be a better leader? Take off the mask.

The best leaders don't project perfection. Peter Fuda explains why.

Videos
  • There are two kinds of masks leaders wear. Executive coach Peter Fuda likens one to The Phantom of the Opera—projecting perfectionism to hide feelings of inadequacy—and the other to The Mask, where leaders assume a persona of toughness or brashness because they imagine it projects the power needed for the position.
  • Both of those masks are motivated by self-protection, rather than learning, growth and contribution. "By the way," says Fuda, "your people know you're imperfect anyway, so when you embrace your imperfections they know you're honest as well."
  • The most effective leaders are those who try to perfect their craft rather than try to perfect their image. They inspire a culture of learning and growth, not a culture where people are afraid to ask for help.
