counterfactuality

Imagined alternative reality

Counterfactuality is the quality of being contrary to what actually happened or exists.

It's the essential feature of statements like If I had left earlier, I wouldn't have missed the train—scenarios that imagine alternatives to reality.

Philosophers and logicians use counterfactuality when analyzing causation, since understanding what would have happened under different conditions helps establish what actually caused an event.

The concept appears in everyday reasoning whenever we consider roads not taken.
