Just a handy hint at the beginning on the meaning of sophisticated minds, people who possess creative, challenging, and disruptive mindsets. Non-conformists.
Whether they are journalists, doctors, writers, etc regardless of the profession, most people usually conform to the norms, policy, and strategic direction of their organizations. Deviating from the general line threatens jobs and permits managers to tighten the reigns. Your views must be in line with the general line.
The problem is that over time, these few sophisticated minds get diluted and weakened, their constructive and creative power will be sapped by conformance and compliance. Sophisticated minds are independent and free voices by nature. they cannot camouflage too long.
