Conclusion: there is a gap between the reality of how police officers make decisions
and how the criminal justice system (and the general public) expects them to make decisions.
Given the uncertain, dynamic, and pressure-filled nature of criminal investigations and the demands of the adversarial justice system, it is not reasonable to recommend that police officers use “optimal” decision-making strategies. Just like a substantial number of psychological researchers over the past several decades, those who cite tunnel vision as a cause of wrongful convictions have made a very important oversight – investigative decisions are made by humans in the real world, not by supercomputers in some ideal place where time, knowledge, and resources are unlimited. Decision-making strategies that ignore information, including the
heuristics that comprise tunnel vision, are thus more psychologically and ecologically plausible than those that strive for optimality.
