In Michael Crichton's book "Disclosure," the theme of friendships is explored alongside the importance of competence in professional relationships. The quote "Friendships are nice. So is competence." highlights the balance individuals must strike between personal bonds and the need to demonstrate skill and effectiveness in their work environments. This duality serves as a reminder that while personal connections are meaningful, the ability to perform well is equally crucial for success.

The narrative emphasizes how these two elements can sometimes conflict, particularly in competitive settings. Characters navigate their relationships while confronting the pressures to prove their capabilities, illustrating how friendships may be tested in the pursuit of career advancement. Ultimately, Crichton suggests that both types of interactions play significant roles in shaping one’s life and career decisions.
