No one is proposing repetition for its own sake. The point of repetition is to create rigor, and you can't do rigorous science without repetition.
> Paying for the cost of mountains upon mountains of lab techs and materials that it would require to replicate every study published in a major journal just isn't a good use of ever-dwindling science dollars. Replicate where it's not far off the critical path. Replicate where the study is going to have a profound effect on the direction of research in several labs. But don't just replicate because "science!"
I could see a valid argument for only doing science that will be worth replicating, because if you don't bother to replicate you aren't really proving anything.
