Breaking windows increases the need for new windows, thus paving the wave for new window technology. But you could have researched that anyway, without breaking the window first. When you are forced to research something b/c of a broken window, or war, you set aside what would have otherwise been a higher priority. Being forced to do something is not a good way to discover the best priority. Free choice, while imperfect, works better.
