It's not NIH (not invented here) but it's the same sort of ego-centric thinking. Maybe it's:
only I am brilliant enough to think of this idea = OIABETTOTI or my bright idea is best BIIB. I think there's a recurrent pattern among smart people of thinking no one ever before has had this great idea when the fact is someone probably has had a similar idea.
I'm picking on my favorite President, who wants to set up a farmers market for DC by closing Vermont Avenue on Thursdays.
But there are eighteen farmers markets in DC. Have the people in the White House thought about this? You need both supply and demand for a successful market. There's not many people living near the White House, so the demand is going to be mostly office workers picking something up for the evening. Doesn't strike me as the best prospect.
