I've had lots of junior and entry level engineers who are frankly intimidated by their team. Someone will have a decent idea but not bring it up in a group session because "Jane has a PhD and 15 years more experience than I do, their idea is probably better so I didn't bother".

You know what? Most of the time they are right. But it's still important to have a culture where everybody feels comfortable presenting their own ideas and critiquing others - not because we're going to discard the sr. staff persons architecture in favor of the interns idea very often, but because the process is good for the ideas, good for the product, and good for the team members (whatever level).
