Being reducible is part of it, but I think reproducible is more important. Psychology is not reproducible. You can get statistical equivalents, but not exact reproduction of results.
I think being reducible is all of it. Even if it’s reproducable you can know THAT something is true, but not WHY it’s true. I think the why, or at least the ability and intention to get there, makes something a hard science.
