Strategies and example responses. a, Percentage of patients with hippocampal damage (red) and healthy control participants (blue) who responded “yes” to debriefing questions for the personal high-conflict scenarios. The majority of patients with hippocampal damage responded to the high-conflict scenarios based on an emotional rejection of causing harm to even one person. The majority of controls used strategies that additionally took account of rational issues pertaining to future benefits when deciding in which cases it would be excusable to harm somebody. Moreover, whereas the majority of patients with hippocampal damage did not visualize the high-conflict scenarios in greater detail than any of the other scenarios, control participants visualized vivid scenes in greater detail for the high-conflict than any other scenario classes. b, Examples of strategies used by the patients and healthy controls.
