While existing research has suggested that being in a biophilic work environment (BWE), or environments that incorporate nature and natural elements, would generally have positive implications for employees, our understanding of the potential downside consequences of this contextual setting is underdeveloped. Leveraging insights from Attention Restoration Theory (ART; Kaplan & Kaplan, 1989; Kaplan, 1995) and the biophilia hypothesis (Wilson, 1984), I hypothesize that the natural features of BWEs may draw one’s attention away from tasks at hand and trigger employee complacency, thereby decreasing beneficial workplace behaviors, including proactive behavior and prosocial behavior. Furthermore, I argue that the positive relationship between BWEs and complacency may be stronger for employees who are lower (vs. higher) in mindfulness. Results were mostly supported through three pre-registered studies: 1) an online experiment conducted with working professionals on Prolific Academic, 2) a multi-source field study involving 219 coworker dyads (438 employees) across 111 organizations in the Republic of Korea, and 3) an in-person experiment with undergraduate students at a large eastern U.S. university. Collectively, these studies aim to offer significant insights and implications regarding the consequences of various workplace environments.
