Final answer:
The 'disturbance handler' is not one of Mintzberg's interpersonal roles but rather one of the decisional roles he identified. Mintzberg's framework for managerial roles is mistakenly conflated with the disturbance theory related to interest group formation in politics.
Step-by-step explanation:
The statement that the 'disturbance handler' is one of Mintzberg's interpersonal roles is false. Henry Mintzberg, a renowned management expert, proposed ten managerial roles categorized into three groups: interpersonal, informational, and decisional. The disturbance handler is actually one of the decisional roles, not an interpersonal role. In this role, managers deal with unforeseen issues and crises that arise and must respond to them effectively. In contrast, the interpersonal roles according to Mintzberg include figurehead, leader, and liaison.
In relation to the provided information, the disturbance theory is a political concept suggesting that interest groups form in direct response to changes in society and government. However, this theory is not directly related to Mintzberg's management roles. Additionally, economic bias refers to the disproportionate influence certain groups have due to their resources, often aiming to affect economic policies which could be championed by economic groups. These groups concentrate on economic issues like wages and profit maximization, amongst others, which is a separate topic from Mintzberg’s managerial roles.
