Environment-leader congruency yields better adaptability manifested in better decision-making. The military combat environment offers advantages for leaders with ADHD; though they are expected to encounter difficulties due to executive dysfunction. This research aspired to increase the congruency effect for leaders with ADHD in a stressful military environment through interventions that improve executive decisions. We hypothesized that making decisions in isolation will improve decision quality overall; while face-to-face interventions that activate commitment and focused attention will promote decision-making particularly among respondents with ADHD. A large-scale controlled study explored candidates’ responses to combat dilemmas under four randomly assigned interventions: Isolation, Simple face-to-face, Withholding response face-to-face; and Control-peer-group classroom setting. The main effects of improved decision-making in isolation and simple face-to-face settings were shown across groups. Further, both face-to-face interventions interacted with ADHD, yielding stronger effects and better performance among participants with ADHD as compared to those without ADHD. Current findings highlight the importance of finding suitable conditions for enabling improved executive decisions among candidates with ADHD. Introducing economical and easy-to-operate face-to-face interventions enhances decision quality in a highly represented neurodiverse population. Current findings may generalize to an array of high-risk/high-stress working environments, providing ecologically relevant support for young leaders from neurodiverse populations.
