According to eaton and colleagues (2009) when does resistance to attitude change peak?

According to Eaton and his colleagues, middle aged adults reach the peak of resistance to attitude change levels. The authors explain that they believed this concept happens because middle age adults are the majority of the work force of any society. Because they have the working roles with the most amount of power, they experience a higher level of resistance to change or to persuasion from others. Their jobs ask for a high level of resolution and decision power, and these factors contribute to them not responding well to change attitude.
