It's the exact same issue that science has. Reproducing past work won't get you funding so no one bothers unless there's no alternative. Negative results won't get you funding so no one publishes them which means people inevitably repeat the same failed experiments. It seems like large institutions almost inevitably accumulate misaligned incentives along with an inertia that makes them almost impossible to correct.
