The more an engineer knows the more they realize they don't know.

The most experienced engineers will provide an assessment/analysis based on observables and available data. Rarely will you get a definitive answer, unless the question posed has a very obvious outcome. Even then, project management will usually receive the answer in the form of a risk assessment. At that point management will need to weigh technical, schedule and cost risks to choose the path forward.

Less experienced (younger engineers) are more prone to acting like they know it all, and usually need some humbling experiences to realize how little any one person knows about complex issues with many variables.
