Immunization techniques build up the jurors' defenses to the opposition's arguments. Analogous to the medical term, immunization fosters resistance to persuasion by treating the jurors before they are exposed to the opposition's argument. Forewarning refers to the fact that when people are aware of the coming persuasive attempt, they can prepare themselves. The old adage forewarned is forearmed applies here. If jurors become aware of upcoming persuasive attacks or tricks, they can more effectively resist these attacks.
Supportive arguments are ammunition jurors have to resist the opponent's attacks.
However, the effectiveness of supportive arguments is diminished when they fail to address information or arguments presented by the opposition. Inoculation builds the defenses of jurors to the opponent's persuasive attempt by fostering the ability of the jurors to develop arguments against the opponent's position. When jurors are presented with a weakened form of the opponent's argument and they are successful in refuting it, the jurors will be more able to resist the opponent's arguments in the future. An additional benefit of inoculation is a generalized resistance to arguments not specifically addressed in the inoculation process. Rhetorical questions guide the jurors' search for answers and, in some cases, imply answers on their own.
