I disagree that anyone is "naturally-inclined" to be better at algorithms, or coding, or abstract thinking. Rather, approach it as if we've been a blank slate that has picked up techniques and patterns of thinking, as throughout our lives we've been confronted with problems that required a new way of thinking. I'd reckon that someone you see as "naturally inclined" has simply encountered problems before that lend themselves to abstract in a similar way as these new problems they face (algorithms, architecture, speaking Japanese).

If you believe my paradigm, then you start to realize that not only is your mind extremely flexible, but that by focusing on a varied set of similar problems, you can start developing a framework to pick up more skills faster, and thus develop that "natural inclination" in the field you practice.
