If your plot gets stuck, research often helps to get it moving again. Details add credibility to your story and can also provide new plot angles. It never hurts if your reader learns something along the way, whether it’s about the setting or the protagonist’s job.
For example, if you’re writing a mystery, knowledge of police procedure is important, particularly forensics. Getting it wrong will throw readers who know better out of the story and your credibility is lost. The same goes for any other profession. This is where writing what you know works best, unless you’re willing to learn about others through talking to someone or research.
Marcha's Two-Cents Worth 
A writer I knew long ago, had a small treadmill in her office. When her plot would get stuck, she would get herself moving and she always swore that she could ‘walk herself out of stuck’. I tend to weed myself out of stuck. Both options involve the author doing something aside from staring at the computer screen.

So true! I get my best ideas doing some brainless chore like washing dishes, mowing the lawn, vacuuming, or on my stationary bike. It allows our subconscious ideas to surface.

Which is why I mentioned walking and weeding. Too often we writers spend our time in unproductive ways when we could ‘kill two birds with one stone’ so to speak. I, for one, filled a recycling bin this morning.

Yes, it has helped my attitude toward these chores a lot as I’ve come to realize they’re really not taking timing away from my writing at all.
