Yeah, but it's hard to get funding to do a rigorous replication of something that doesn't have an immediate commercial justification (for example legal liability or FDA requirements in drug trials). It's a big investment where the best case scenario is that you can be a little more confident in prior results. And if you can't replicate the results, it doesn't necessarily mean the original finding was wrong, it could just mean the original scientists were better than the replication scientists.

Also, among scientists who have invested the time to earn a Ph.D., there is a culture of wanting to break new ground and push humanity forward. There would have to be a strong incentive to motivate them to invest the time in replicating research for which they won't get the glory.

You would have to change the way science is funded to make research replication a required step in the modern scientific method.
