Stop Checker diagram is built to identify false, misleading, and incorrect information. The diagram identifies problematic situations that could take an individual off track. When a person is misled with misinformation, they have the ability through the diagram to check the error, make a correction, and move in the direction of a better outcome before wrong doing, illegal activities, or financial loss occurs. Sometimes individuals are pressured to make illogical decisions for others gain. Stop Checker helps the user stop the direction they are going. The diagram builds a foundation that promotes assertiveness to say no and contemporary evidence to justify the decision made. The diagram can also help the user forensically analyze and report peer pressures that led the user to make a mistaken statement or action and report the information to management in business or individuals involved in the user's personal life.
