I think the reasonable explanation is that logic works great for simple systems, but once there are more than, say, seven variables involved, nobody can properly reason in real-time anymore. Personal relations, politics, raising a child, finding out what to do with life, selecting a web framework, all involve millions of variables.

Even if some abstract concepts (love, power, friendship) allow a scientifically minded person to consider complex systems as simpler ones, the underlying complexity is still there, and is relevant. Human ecosystems do not adhere to Maxwell's laws.
