Most of the comments so far, this one included, evade one aspect of creativity in the sense of unconventional ideas. The risk associated with testing out a truely original hypothesis is often greater than we can actually comprehend even far into the experiment; but failure doesn't mean the hypothesis was incorrect. We often speak of an idea "before its time", etc., - sadly, in retrospect. These are the ideas we drown by not sharing the risk as a group, ideas that could spare us great amounts of everything from discomfort to pain.
