A distinction should be drawn between changing advice because evidence has improved and changing it without an explanation. The former can demonstrate care rather than weakness. Nevertheless, audiences may have incurred costs by following earlier guidance, and an appeal to uncertainty does not erase those costs. Responsible experts should explain what changed, acknowledge the consequences and indicate which parts of their advice remain provisional. Credibility depends less on never revising a claim than on making the grounds for revision open to scrutiny.
