I'd like to learn more, could you please provide some sources.

Based on the recent Ranga Dias fraud, I'd think replication culture still has a long way to go.

Is that true? Do you have any citation? It sounds incredible. Every study?

It's broadly true that most research is eventually subject to attempts at replication. However the replication isn't explicitly attempting to reproduce the exact prior research, but to build on it.

If the foundation established by the prior research is flawed, attempts to build on it will usually fail.
