Not really. Engineers venture out into the grey even more than scientists do - they solve problems of interest to humans - their job requires them to be grounded in reality and be sensitive to human needs and constraints (well, at least the good ones are).

I often think that while a purely technical background and education might be really powerful and enable one to analyze and predict well-behaved things better than others - which could lead to better decisions, it is extremely important to be receptive to the "inexplicable-until-experienced" stuff like music or business or relationships - to know that there are things that can't be controlled and shouldn't be controlled - that some things should evolve of their own accord - the chaotically evolved imperfect being more beautiful than the mathematically-designed perfect. (Edit: a combination of both works quite well, in my experience - some of the best businessmen, economic and political advisers I know of have engineering backgrounds - and no, they aren't unreasonably conservative or dogmatic).

In my opinion, the fear of "what will happen if I let go?" can lead to authoritarianism via technocracy (aside from the fact that anyone can get drunk on power) - not one's profession.
