The whole goal of research in today's society is to publish it. This is because the more you publish the more likely you are to be funded for the next experiment. An experiment usually takes at least a few years maybe more and therefore cannot be replicated quickly. If you do not want to "get scooped" by someone else in the field you need to publish as soon as you have the results. So basically it would take too long to get anything published if you had it in the peer review process.
