The modern research community knows they aren’t producing the best science they could be. There’s lots of publication bias, statistics are done in a confusing and misleading way out of sheer inertia, and replications often happen very late or not at all. And sometimes someone will say something like “I can’t believe people are too dumb to fix Science. All we would have to do is require early registration of studies to avoid publication bias, turn this new and powerful statistical technique into the new standard, and accord higher status to scientists who do replication experiments. It would be really simple and it would vastly increase scientific progress. I must just be smarter than all existing scientists, since I’m able to think of this and they aren’t.” And yeah. That would work for the Science God. He could just make a Science Decree that everyone has to use the right statistics, and make another Science Decree that everyone must accord replications higher status. But things that work from a god’s-eye view don’t work from within the system. No individual scientist has an incentive to unilaterally switch to the new statistical technique for her own research, since it would make her research less likely to produce earth-shattering results and since it would just confuse all the other scientists. They just have an incentive to want everybody else to do it, at which point they would follow along. And no individual journal has an incentive to unilaterally switch to early registration and publishing negative results, since it would just mean their results are less interesting than that other journal who only publishes ground-breaking discoveries. From within the system, everyone is following their own incentives and will continue to do so.
