I don't know what you base this assumption on, but generally I would say the real world is quite the opposite.
In Human Factors it is a general view that premature decisions and too fast judgements are more frequent among less experienced crews than the more experienced.

As a sidenote it is quite amusing when you can tell the experience level of a first officer by the speed of his/her after start flow on the overhead panel. The less experience the quicker they pull all the switches.
