Decisions made by people who don't understand technoloy

Recently I've found myself in the situation where many of my recent managers think they know much more than they actually do about technology. They go to meetings with their ill conceived assumptions and make major decisions without consulting any of the technical people. When the tech savvy people actually find out that a decision has been made, often it is too late to change it. It seems like a bad case of chinese whispers where the facts get distorted as they get passed up levels of management.
