better described as shadows are on the left, highlights are on the right, and the middle. Sounds funny calling it blacks & whites when you get into RGB curves (though not actually false).
say you had a portrait where a girl was standing on a blue floor, but in the picture, the floor's color looked inaccurate, and her arm was brighter than her face.
Using curves, you select out the floor, drop a color sampler on it, and see that the floor looks a little magenta.. apply curves to the selected area and mess with the Green channel until it looks right.
Similarly, the girl's arm is too bright. Select her arm (color range selection is usually pretty good for this), then do curves and pull down the curve on the highlights part (the right side) until it looks right.
There is a lot of experimentation with curves, but if you remember left = shadows and right = highlights, youre starting out from a much better place.

doing an S-shaped curve is teh same thing as upping the contrast slider in brightness/contrast... it's no more a good starting point than any, and really depends on if the picture needs more contrast.
