And call me a cynic, but I am a market research analyst - more of a stats-lover than most, I'm sure - and even I think this new holiday is lamer than National Chocolate-Covered Insects Day.
"Celebrating the many contributions and achievements of official statistics?" Nice tag line, people.
Beyond that, as valuable as statistics can be, they can also do a lot to harm. They're perfectly malleable, even when they're "official" (maybe especially then) and people will always use stats to support their own agendas, rather than deciding their agendas based on those stats. It's human nature.
So sure, celebrate the statistic. But let's just be realistic about it, OK?
