Crises everywhere

Nothing beats a "crisis" to rally support for a big government effort. Right statists constantly drum up moral panics about sex and drugs. Also, Mexicans are "invading" and terrorists will surely blow us all up while singing the Star Spangled Banner at baseball games if we don't allow the executive Jack Bauer to torture military detainees whenever he wants. Similarly, left statists warn that the shores of Manhattan will be inundated by rising oceans and very cute baby polar bears will die in droves. Also, inequality is soaring, threatening the foundations of democracy. And the middle class lives in terrifying "economic insecurity." And so on.

By comparison to people on both the left and the right who would like the government to do something, libertarians can seem either ostrich-like, pollyanna-ish, or both. I suspect the "everything is going to be OK so the government can just stay out of it" bias played a key role in motivating many conservatives and libertarians to be favorably disposed toward skeptical findings about global warming. Let's call this "libertarian optimism bias." But I also suspect that the "OMG! there is a huge crisis so the government has to do something NOW" bias is at play at least as strongly in a number of important issues. Let's call this "statist pessimism bias."
