In persuasive communication, the inoculation effect involves warning listeners that others will try to influence them in the future and that they should be aware of the opponent's arguments.

The inoculation effect is a real phenomenon in persuasive communication, where listeners are warned about future attempts to influence them and are given a brief sample of the opposing argument in order to strengthen their own position. This helps to counteract the effect of future attempts at persuasion, making the listener more resistant to manipulation.
