Brevity is okay if it doesn't spawn comments like some I saw in the rest of this thread when i first read it, which I'm going to paraphrase rather than quote directly: "we're talking about everyone because it's an average"

I dont know how to educate people use, interpret and critique statistics, but I know I'd rather the tweeters were even more brief and just pointed to a source that does a decent job of showing the data and give people a chance to learn numbers can be used summarising what's happening to a population.

If they're just quoting a few numbers to support their opinions they can fuck off for all I care - that's not actually going to help people understand what's going on - or how the data can help them do so. It just creates more hot air. And whatever they pick, there is a counter argument ususally everyone can find a cherry that sounds plausibly representative of far more than it actually is.
