'''Counterfactual thinking''' refers to the human tendency to construct mental representations of alternatives to events that have already occurred — in other words, to imagine how the past could have unfolded differently. Derived from the philosophical notion of a "counterfactual conditional" (a statement of the form "if X had been the case, then Y would have followed"), the concept entered empirical psychology in earnest through the landmark work of Daniel Kahneman and Amos Tversky in the early 1980s. Their investigations into the "simulation heuristic" demonstrated that people routinely run mental simulations of unrealized possibilities, and that the ease with which an alternative scenario can be imagined powerfully shapes emotional and judgmental responses.

The cognitive machinery underlying counterfactual thought draws on the same representational systems used for episodic memory and prospective imagination. Neuroimaging studies have shown that generating counterfactuals activates overlapping regions of the prefrontal cortex and the default mode network — the same circuits involved in remembering the personal past and mentally projecting into the future. This suggests that counterfactual thinking is not a cognitive anomaly but a fundamental feature of how the human mind processes events in time.
