Fresh eyes are always better equipped to ask “Why” to poke at (no longer necessary) Cheshire Fences. Their ignorance (by virtue of being new) gives them cover to question things. This doesn’t necessarily mean inexperienced people, but that does give even more cover to ask the very necessary “why” and get answers, and excuses their lack of familiarity to intuit the situation.

Junior people also tend to have the humility to know they’re inexperienced and lacking insight, so they tend to be more willing to “follow” the senior employees rather than attempt to leave their mark as a leader. “Too many cooks in the kitchen” and all that jazz.
