 Context:

I have heard it called 'thinking above the curve'. And it's that; I have heard it called the 'over-logic', and it's that too. Whatever you call it, ...

Thanks CJ. More context below:

 At one moment I had none of this; at the next I had all of it. If there is any one thing I love about writing more than the rest, it's that sudden flash of insight when you see how everything connects. I have heard it called "thinking above the curve," and it's that; I've heard it called "the over-logic," and it's that, too. Whatover you call it, I write my page or two of notes in a frenzy of excitement and spent the next two or three days turning my solution over in my mnd, looking for flaws and holes(also working out the actual narrative flow, which involved two supporting characters placing a bomb in a major character's closet), but that was mostly out of a sense of this-is-too-good-to-be-true unbelief. Too good or not, I knew it was true at the moment of revelation: that bomb in Nick Andros's closet was ging to solve all my narrative problems. It did, too. The rest of the book ran itself off in nine weeks.

As the writer explains, those are some terms for a flash of inspiration he gets as an author. Read the whole paragraph again - the paragraph is telling you about an experience he has as an author. He has heard that experience referred to by those two phrases.

Above the curve means above the (statistical)  average/median, above the habitual/usual/normal.
