It sounds like use in moderation might make it easier to rapidly leap around the conceptual problem space, perhaps reaching apparently unrelated insights. This tallies with the stereotype of being good for creativity.

At higher doses, this would be overshadowed by the negative effects (leaping too far around the problem space, into nonsensical ideas, deleterous effects on memory and motivation.)

I presume an experienced user could differentiate, judge their own reactions and moderate accordingly. I don't believe I could.
