Final answer:
The statement that subtle forms of resistance create the greatest obstacles to change is considered true because they are harder to identify and address, leading to delays and obstacles in implementing reforms.
Step-by-step explanation:
According to some experts, the subtle forms of resistance create the greatest obstacles to change because they are not as visible. This statement is generally considered to be true. Invisible forms of resistance, such as passive aggression, silent non-compliance, and various stalling tactics, are often the most challenging to identify and address. These subtle actions can hinder reform efforts by creating delays and obstacles that are not immediately apparent, making it difficult for change agents to effectively implement new policies or practices. For instance, in government bureaucracies, counter-reformers may use such tactics subtly to stall necessary changes without drawing direct attention to their resistance.
