Almost every time I fact-check something I see breathlessly claimed in online discussions, I find the truth is less extreme than the assertion, regardless of the issue or the viewpoint doing the claiming.

Oh shit yes, this is so true it should be on the banner of every site like this.

"Solar PV never produces more energy than it took to make!"
"Solar PV can be made for a dollar a watt!"
"Nuclear is perfectly safe, just put the waste in a barrel and bury it."
"Nuclear is really dangerous, everyone near the plants is heaps more like to get cancer."
and so on.

So, as Pitt says, when we meet statements like,

"We're facing a dieoff."
"Science! and The Market! will save us the trouble of actually doing anything."

we have to be sceptical...

Are you actually trying to say anything?
