A seasoned actuary once said that the most dangerous number in finance is the one everyone agrees on. Xunzi, the least-read of the great Confucian thinkers, made a related observation in the 3rd century BCE: group consensus doesn't refine truth — it launders error. His concept of 'zhengming' (rectification of names) insists that muddled language produces muddled judgment, and that professional communities are especially vulnerable because shared jargon creates the illusion of shared understanding. Daniel Kahneman found the same trap in his work on 'groupthink in forecasting' — teams in financial institutions routinely suppress dissent not from malice, but because the vocabulary of the room doesn't have room for uncertainty. Today, before you accept a term, a number, or a framing at face value in any meeting or report, ask yourself: does this word actually describe the thing, or does it merely describe how we've agreed to talk about the thing?

What is one term you use regularly at work that, if pressed, you couldn't define precisely — and what might be hiding in that vagueness?
