“…Gouldner [10] already depicted a failure by an outsider plant manager due to detachment from subordinates, which caused mistrust and concealment of managing-essential knowledge, as found by others [11][12][13]. Many studies sought to clarify which type of CEOs are preferable, outsiders or insiders, but findings remained contradictory [14] as they missed the outsider's prime dilemma: Shall I dare vulnerable involvement in deliberations with subordinates, exposing my gaps of their exclusive tacit know-how, phronesis, and premises of decisions in order to build full trust and share these intangibles, or by distancing from them, should I conceal my gaps of local experiential knowledge and defend and augment my authority [15,16]?Outsider executives often defend their authority by low-moral concealment of their own gaps of subordinates' exclusive tacit know-how, phronesis, and premises of decisions, avoiding trust-creating vulnerable involvement (T-CVI for short) in deliberations with subordinates rather than high-morally admitting gaps, building subordinates' full trust, and encouraging sharing of these intangibles [6,7,16]. Research rarely alluded to outsiders' dilemma concerning practicing T-CVI that is decisive for creating the full trust required for subordinates' sharing of tacit knowhow and phronesis developed and learned in "the unceasing flow of activities in which practitioners are inextricably immersed" ([2], p. 377).…”
