The world of science has been stuck in an existential crisis over whether we actually know the things we thought we knew. Re-running an old study today doesn’t always yield the same result. Same with re-enacting old experiments. Collectively, this is known as the “replication crisis.”
Economist Abel Brodeur has come up with one way to help fix this crisis: he’s invented an internationally crowdsourced surveillance system, designed to keep social scientists honest. He calls it the “Replication Games.”

ICE is scaling up, with rapid new hiring. So we ask, has training new officers changed? At what cost?

Greenland has said it is not for sale. Denmark has said it can’t even legally sell Greenland. And at a security conference in Munich over the weekend, U.S. lawmakers spent a lot of time trying to walk back some of President Trump’s recent threats to try to buy, or even take over, the territory.
But whether Trump can or will or should try to control or purchase a territory that doesn’t want to be sold is not the interesting question. What is interesting is how we got to this moment. And, how we might gracefully get out of it.
Greenland is valuable for its minerals and because of its physical location in the world. (It’s easy to keep an eye on other countries from Greenland).
Our latest: How the U.S. dropped the ball on the rare earths race. And one way the U.S. gets strategic locations without threatening to buy or take over an entire territory.
