Your most experienced supervisor is your biggest literature risk. Here is why that is not a criticism.
Senior supervisors are genuinely excellent at literature. They know which papers matter, how ideas evolved, who the influential figures are, what the open problems are. That knowledge is real and it took decades to build.
But it was built inside one citation network. 20 years of depth inside one network means 20 years of reinforcing what that network considers important. Their instinct for the important papers is calibrated to the field they built their career in. It is not wrong. It is local.
The adjacent literatures they do not know are not gaps in their knowledge. They are the natural result of the trade-off between depth and breadth. They chose depth. You are inheriting that choice without realizing it.
What to do: take their deep map seriously for positioning once you have a question. Before you have a question, read outside the edges of their map. Their depth is the resource. Their edges are yours to find.
Knowing this is your responsibility, not theirs.
