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.

What's interesting is that the senior leaders of Singapore were often trained in engineering, and some have attributed their technocratic and unpopulist approaches to the engineering mindset. For them, it's all about making things that work, but the secondary/knock-on effects sometimes don't get considered or noticed until it's too late.

Funnily enough, in our media it was reported that of late, students receiving top-level government scholarships to the US/UK/elsewhere hardly ever choose engineering any more, but study economics instead (probably influenced by the dominance of the financial industry). So the next generation of Singapore leaders may very well be dominated by economics trainees - I wonder what sort of government we'll get, then? Certainly a more diverse one, but also one lacking in engineers and scientists.
