Professor Jim Walsh played a significant role in the development of work on individual, group, and collective cognition in organizations. Interested in managerial mistakes, Walsh wanted to know if executives’ worldviews could blind them to their decision environments. He was also interested in learning how the cognitive capabilities of both leadership teams and the organization itself could be harnessed for the good of organizations. In a 1988 Academy of Management Journal article, Walsh traced how these belief structures might or might not blind executives to their decision environments. He also considered how these belief structures may or may not combine to shape team decision-making. Therefore, he wrote a theoretical paper about these possibilities, which was published in the Journal of Management in 1986. He followed up that article with an empirical effort to measure and trace the impact of “negotiated belief structures” on decision-making (Organizational Behavior and Human Decision Processes published his findings in 1988). His thoughts then turned to the organization as a whole. He wrote a seminal paper on organizational memory, one that identified the nature of information selection, retention, and retrieval processes in organizations – for the good or ill of those organizations. That work was published in the Academy of Management Review in 1991. When interest in cognition in organizations started to grow, Walsh became a founding officer of the Academy of Management’s Managerial and Organizational Cognition Interest Group in 1990 and helped to lead that pioneering group of scholars for the first three years of its existence. Tying all of the insights and experiences together, he wrote what became something of a field-defining scholarly paper in 1995. Titled “Managerial Organizational Cognition: Notes from a Trip Down Memory Lane,” it was published in Organization Science. Today the Managerial and Organizational Cognition Division of the Academy of Management is home to more than 1,200 scholars worldwide. Citing his foundational scholarship and early leadership, the Division honored Jim with its Distinguished Scholar Award in 2020.
