I suspect if you actually speak to a scientist, you'll find they really do not ignore the complexity of their subjects. However, the public starts at such a base level, that it's impossible to even engage at the limits of their research. And the honesty of the scientists with regards to their understood complexity often times does them more harm then good. Their carefully chosen, complex-laden words are glossed over in news headlines that extinguish the nuance. Ask a genetic researcher if "GMOs can harm humans" and the answer will likely be, "Probably not". But this actually means - "I can conceive of nothing but the most fantastic route for that to happen. And even if it did it would have to happen by a route currently unknown or at the edge of our entire field." When in reality the public clings to really strange notions that truly are scientifically incorrect. You can make the argument that being correct for the wrong reasons has its advantages, but in real life no single action ever taken is without risk. It is precisely the scientist who has dedicated her career to her work that understands (and even thrives in) its complexity.
