This is also similar to providing massive numbers without any context. For example $x produces 2.3M tonnes more $waste than $y every year!!! Of course $y produces 8.2T tonnes a year so it isn't /that much/ of a delta. Also vaguely related to my pet peeve of using large denominators to make numbers large and confusing. This factory produces 63M items a year! How about 2 per second, I can visualize 2.

> Also vaguely related to my pet peeve of using large denominators to make numbers large and confusing. This factory produces 63M items a year! How about 2 per second, I can visualize 2. smaller denominators can also be misleading though. maybe this is just me, but I usually read the denominator as implying a time period over which the figure is stable. for example, before the pandemic, I drove about 40 miles/day. I really did drive 20 miles each way to work pretty much every day. another way of saying this is that I drove 1.6 miles/hour every work day. true on average but kinda misleading when I spent 23 hours out of the day not driving at all. it might not matter much to your example, but the factory probably didn't produce two items every second. there were probably shift changes, or maybe it stopped production for a few hours every night. depending on market conditions, it might have produced more on some days than others, and so forth.

  That is true. There are cases where the timeframe is important, but often it isn't. I definitely should have put "on average" in there. You can also be more clear and say "Produces 5 per second when running at full capacity, averaging 2 per second throughout the year" if that is appropriate for the info you are sharing.

There's a vague prescription in Thinking Fast and Slow that an objective person attempting transparency should present both versions of the numbers. Example: .15% or half a million Americans died. What policy changes if any should we enact to try to compromise between lives lost and GDP, as lower GDP compromises (for instance) our influence in the international community. Versus: Side 1: it was less than one in 800 people. This is hysteria. Side 2: What do you mean hysteria, we lost HALF A MILLION PEOPLE and it could have been 3 million if we had done it your way. Side 1: 1 in 800 is not that many. Side 2: 1 in 800 is a lot, actually.
