Methods of evaluating the effectiveness of a message in changing the opinion of a person are provided. A person's opinion on a position statement is obtained and given a numerical value, after which the person assesses several messages related to the position statement based on how convincing each message is to that person, assigning a numerical value to each message. The person's opinion on the position statement is then re-assessed, and for any person whose opinion has changed in a certain direction, the numerical values for each message are averaged to obtain an effectiveness score for each of the several messages. |
