The past and the future influence the present, for decision makers are persuaded by historical patterns and styles of decision making based on social, political, and economic context, with an eye to planning, predicting, forecasting, in a sense, “futuring.” From the middle to the late 20th century, four models (rational-bureaucratic, participatory, political, and organized anarchy) embody ways of decision making that provide an historical grounding for decision makers in the first quarter of the 21st century. From the late 20th through the first two decades of the 21st century, decision makers have focused on ethical decision making, social justice, and decision making within communities. After the first two decades of the 21st century, decision making and its associative research is about holding tensions, crossing boundaries, and intersections. Decision makers will continually hold the tension between intuition and evidence as drivers of decisions. Promising research possibilities may include understanding metacognition and its role in decision making, between individual approaches to decision making and the group dynamic, stakeholders’ engagement in communicating and executing decisions, and studying the control of who has what information or who should have it. Furthermore, decision making most likely will continue to evolve towards an adaptive approach with an abundance of tools and techniques to improve both the praxis and the practice of decision making dynamics. Accordingly, trends in future research in decision making will span disciplines and emphases, encompassing transdisciplinary approaches wherein investigators work collaboratively to understand and possibly create new conceptual, theoretical, and methodological models or ways of thinking about and making decisions.
