Dilemma of the Day - creativity

- according to A. Gopnik, children begin playing imaginary, i.e. "what if" (counterfactual) games, at the age of 18 months.



Dilemma:

1)to be new (creative) an idea must be counterfactual. that is, it should not exist in real world.
2) the idea should not be counterfactual to be credible/verifiable or adoptable, e.g. in the marketplace.
