So he was biased for his own argument? As much as people try to be unbiased, I think that it's probably impossible for humans to be completely impartial. If the arguments in the recommendation are so weak/faulty then the DOT engineers should be able to rip it to shreds with a counter-argument. I'm having a hard time caring about the fact that the guy put together a 'professional-looking' analysis without having a professional license. He didn't represent himself as a professional engineer, and he was putting together information for to present his viewpoint to his local representatives.Practicing engineers, however, figure out how to do what the client wants within the limits of the law. I usually don't link to youtube videos, but this pretty much sums up the real world: http://www.youtube.com/watch?v=P9BUyWVg1xI
What are you basing this on?
Amateurs then must be forced to make unconvinced arguments unless licensed by the state?
It may be that there's a danger of ignorant people being fooled by those who can spout seemingly convincing, technical arguments. But in a democracy, the only defense is to argue against them and educate the populace. Any other course clearly invites the "dictatorship of officialdom", something that has prevailed in many places throughout history.
I always start with the conclusion- "I want this to do X"- and then I throw together something that will hopefully do X.
If you don't know what your desired conclusion is, you'll get utterly lost and unfocused along the way.
