We can have tiers. Tier 1 peer reviewed. Tier 2 peer replicated. We can have it as a stamp on the papers. All PhD programs have requirement for a minimum number of novel publications. We could add to the requirements a minimum number of replications. But truth to be told, a PhD in science/ engineering will probably spend their first two years trying to replicate the SOTA anyway. It’s just that today you cannot publish this effort, nobody cares, except yourself and your advisor.
