Truth is you need both. Some cases call for insulating someone so they can think deeply about one problem. Some require bringing everyone into the fray so you can cross-pollinate ideas. Mis-judge and you get cogs-in-the-machine or status-update-hell syndrome.
Also, of course, the way you treat someone, the kind of tasks you give them, and the style of management and working with them should be tailored to each individual to get the best out of them.
I’m constantly amazed at how many people want to be managed and told what to do, and value “clarity” over freedom.
