Exceptional boards: Environmental experience and positive deviance from institutional norms
Open accessAbstract
Summary This paper explores the phenomenon of positive organizational deviance from institutional norms by establishing practices that protect or enhance the natural environment. Seeking to explain why some organizations practice positive environmental deviance while others do not, we locate our inquiry on the board of directors—the organizational body that interprets external issues and guides organizational response. We find a strong correlation between positive deviance and the past environmental experience of board directors and the centrality of the organization within field‐level networks. Organizations located on the periphery of the network or whose boards possess a high level of environmental experience are more likely to deviate in positive ways. Our conclusions contribute to multiple literatures in behavioral and environmental governance, the role of filtering and enaction in the process of institutional conformity and change, and the mechanisms behind proactive environmental protection strategies within business.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
