As most of you know, I am a big fan of amusing myself by coining new names for various biases/numerical tomfoolery I see floating around on the internet. I have one that’s been bugging me for a little while now, but I can’t seem to find a good name for it. I tried it out on a bunch of people around Christmas (I am SUPER fun at parties guys), but while everyone got the phenomena, no one could think of a pithy name. Thus, I turn to the internet.
The problem I’m thinking of is a specific case of what I’ve previously called Number Blindness or “The phenomena of becoming so consumed by an issue that your cease to see numbers as independent entities and view them only as props whose rightness or wrongness is determined solely by how well they fit your argument”. In this case though, it’s not just that people don’t care if their number is right or wrong, it’s that they seem oddly unmoved by the fact that the number they’re using isn’t even the right order of magnitude. It’s as though they think that any “big” number is essentially equal to any other big number, and therefore accuracy doesn’t matter any more.
For example, a few weeks ago Jenna Fischer (aka Pam from the Office) got herself in trouble by Tweeting out (inaccurately) that under the new tax bill teachers could no longer deduct their classroom expenses. She deleted it, but while I was scrolling through the replies I came across an exchange that went something like this:
Person 1: Well teachers wouldn’t have to buy their own supplies if schools stopped paying their football coaches $5 million a year
Person 2: What high school pays their coach $5 million a year?
Person 2: $120,000 is not $5 million.
Person 3: Well that’s part of an overall state budget of $20-25 million just for football coaches. (bs king’s note: I couldn’t find a source for this number, none was given in the Tweet)
Person 2: ….
Poor person 2.
Now clearly there was some number blindness here….person 1 and 3 only seemed to care about the idea that numbers could support their cause, not the accuracy of said numbers. But it was the stunning failure to recognize order of magnitude that took my breath away. How could you seriously reply to a comment about $5 million dollar salaries with an article about $120,000 dollar salaries and feel you’d proved a point? Or respond to a second query with an overall state budget, which is an order of magnitude higher than that? It’s like some sort of big number line got crossed, and now it’s all fair game.
I suspect this happens more often the bigger the numbers get….people probably drive astronomers nuts by equating things like a billion light years and a trillion light years away. Given that I’ve probably done this I won’t get too cocky here, but I would like a name for the phenomenon. Any thoughts are appreciated.
