Improvable (vs. too hard to improve)

Beyond simply changing things (which may involve other ideas like fragility), this belief concerns whether or not most things and situations are responsive to our efforts to make them better. The opposite view holds that the world is rigid, inflexible, and unresponsive to efforts to improve it.

The world stands really malleable, waiting to receive its final touches at our hands. 

— William James, Pragmatism, 1907

But it’s too late to make any improvements now. The universe is finished.

 — Ishmael, Herman Melville, Moby Dick, 1851

Improvable is most related to the big-three primal Enticing. This suggests that control may be less important for feeling safe and more important for feeling engaged and having a sense of meaning. However, much more research remains to be done.
