Science relies on replication. And any real gain society gets that comes from science is a form of replication in itself.

Integrity can't be relied on. But then, complete reliability is not necessary, just enough to make replication work.

And also, science is in a crisis due to the lack (or really large delay) of practical use. We actually don't have any other institution that ensures replication happens.
