An eminent American mathematician who has young children writes:
The town [where I live] is forming a committee to study and decide on some town wide curriculum stuff. one of the moms is a professor at MIT. She contacted the town — detailed her credentials and offered some thoughts. They turned her down. essentially they said they didn’t want people coming in with ideas because they knew what they wanted to do and were only interested in applicants with an "open mind" — i.e. would do what they wanted.
