= radical doubt = 懷疑論

Skepticism is the practice of radical doubt—questioning the foundations of knowledge, beliefs, and social conventions. It encourages us to recognize that what we take for granted as “truth” is often shaped by context, culture, and personal experience.

Derek Sivers — Useful Not True

• Almost nothing is objectively true.
• Rules and norms are arbitrary games that can be changed.
• Beliefs are placebos. So you’ve got to believe whatever works for you NOW.
• Refuse ideology. You need to accept ideas individually.

Applications

• Use skepticism to avoid dogmatism ¹ and groupthink ².
• Regularly question your assumptions and seek out alternative perspectives.
• Embrace uncertainty as a source of growth and creativity.
• Remember that changing your mind is a sign of learning, not weakness.
