It’s kind of a shame that reality is too slippery for us to quantify the amount of wrongness. Think of how useful it would be to if we had a unit of wrongness. Let’s say we had a unit – for absolutely no reason at all let’s call it a “beck” – that would allow us to express how wrong something is. “Ooh, close, but you’re wrong by 3 millibecks.” or “Whoa, off by a kilobeck.”
Of course, in our turf the right unit would be a watts. This could lead to some confusion between, say, kilowatts and kilowattses, but watt can you do?
