Pecksniffian progressives

Via George Will today on violent video games today, and corrupting comics from the 50s,

Progressivism is a faith-based program. The progressives' agenda for improving everyone else varies but invariably involves the cult of expertise - an unflagging faith in the application of science to social reform. Progressivism's itch to perfect people by perfecting the social environment can produce an interesting phenomenon - the Pecksniffian progressive.

It's the cult of expertise that rubs me wrong and the failure to measure the trade-offs of submitting to the experts versus any progress towards perfection.
