Why can't we just always tell the truth?

While telling the truth is generally good, "always" telling the truth—especially in its radical honesty form—faces several fundamental problems that make it unworkable as a universal practice. The core issue isn't about truth being bad, but about the complexity of human social structures and individual wellbeing.

The definitional problem: "Truth" itself is often subjective, contextual, or incomplete. What feels true to you in a moment may not capture the full reality of a situation.

The harm principle: Research shows that radical honesty can cause significant psychological damage, with former practitioners reporting cult-like dynamics and emotional abuse within some communities.

Social coordination costs: Human societies rely on tactful communication, privacy boundaries, and contextual truth-sharing to function. Complete transparency would likely break down many cooperative relationships and institutions.

Individual differences: People vary greatly in their emotional resilience, processing styles, and need for privacy. A one-size-fits-all approach to radical honesty ignores these crucial differences.

However, the underlying intuition has merit—reducing unnecessary lies and increasing authentic communication can improve relationships and reduce psychological stress, as shown by Notre Dame research on honesty's health benefits. The key is finding the right balance rather than the radical extreme.
