[apathy]

Graduate students are effectively required to replicate studies already. They just don't get any credit for the work when it turns out that the flashy paper didn't replicate, and the journal editors hate to look foolish, so it's exceedingly rare for failures to replicate to see a journal. So the next graduate student to work on the technique also gets to waste months or years on it.

Really a splendid system, isn't it? Sometimes (rarely) I sympathize with industry types who want grant claw-back processes. Then I remember that those are the same crooks that pushed Vioxx and 510k "equivalent" medical devices. And the sympathy evaporates, because they're even worse.
