I’ve been expressing my disregard for forecasts for almost as long as I’ve been writing my memos, starting with The Value of Predictions, or Where’d All This Rain Come From in February 1993. Over the years since then, I’ve explained at length why I’m not interested in forecasts – a few of my favorite quotes echoing my disdain head the sections below – but I’ve never devoted a memo to explaining why making helpful macro forecasts is so difficult. So here it is.
Food for Thought
There are two kinds of forecasters: those who don’t know, and those who don’t know they don’t know.
– John Kenneth Galbraith
