Perhaps you are mistaking a "I want it that way" attitude to a "God, we have a schedule to meet" attitude.
In some cases I am sure that is true, but I know for a fact in others it was (intentional) ignorance of fact. The facts contradicted what they wanted so they ignored it. Working with these people was very frustrating. Not so frustrating as these threads are though.
BTW, it's not engineers I find trouble with in Scientific Research. I also have trouble with M.D.S doing research. I think the basic problems are the same. People trained in a practical discipline trying to "branch out" into an area they are not adequately prepared for.
Some places are obviously better than others. I'd give 10 years of my life to spend 1 year with Edison at his prime. I understand Stanford Medical School turns out high quality research MDs. But the regular places turn out good, practical engineers and good practical physicians.
