Why could it be more profitable for a beginning researcher to do an exact replication, while it would be more profitable for a seasoned researcher to do a conceptual replication?

What will be an ideal response?

Beginning researchers can benefit from learning how to carry out research by following the well specified procedures of earlier research. This will help them avoid overlooking important potential problems because most of these problems will have been ironed out by the original researchers. Seasoned researchers who can anticipate potential problems can be more confident that they will be able to create well structured studies that go beyond the original studies.
