Conventional wisdom says speak first, speak fast, and never let a vacuum form. Recent research complicates that picture. Not all silence is created equal. Le et al. (2019) identify three distinct types of silence (avoidance, hiding, and strategic delay) and only one of them protects leadership credibility. Used well, strategic silence buys time to get the response right and signals work-in-progress. Used badly, silence is simply evidence you were hiding.
