When you say something you think are just saying something, but you are largely communicating why you had to say it. - Nassim Nicholas Taleb

Heuristic: never trust someone's historical analogies if (as is common with policymakers) his historical knowledge starts in 1934.

Yo, if this piano's the cake then my words are the candles

Injecting some confusion stabilizes the system. Indeed, confusing people a little bit is beneficial — it is good for you and good for them. For an application of the point in daily life, imagine someone extremely punctual and predictable who comes home at exactly six o’clock every day for fifteen years. You can use his arrival to set your watch. The fellow will cause his family anxiety if he is barely a few minutes late. Someone with a slightly more volatile — hence unpredictable — schedule, with, say, a half-hour variation, won’t do so.
