I think that Asimov's observations on the inhibitory effect of visibility and accountability are applicable to the smaller forms of creativity and risk taking like trying new tools and technologies.
I've seen this occur with SCRUM. We had dev team build a new product, burning down backlog through multiple sprints, with an overall results that were pedestrian. By which I mean functional, pretty interface; nothing to complain about really, code was reviewed, tests passed, etc. But you were left wondering there is a better fundamental approach to the problem.
Then they got a bit of down time and someone on the team prototyped a new architecture that would have halved the development effort. This exploration could have been done at the beginning and had been thought of by the person concerned, but the talented - and introverted - individual didn't advocate for it in the face of daily stand-up and burn-down visibility.
