Movies love to portray the inner and outer conflict that arises from being blackmailed, especially when someone's life hangs in the balance. There is the villain (the blackmailer), the victim (the target), a demand (what is being asked for), and a threat (what negative thing will happen if the victim refuses to comply). But blackmail does not have to be a life or death threat to be real. It can be more subtle than that.
BlackmailHere are a couple of examples in everyday life. At school, one child says to another, "If you don't say I'm the coolest, then I'll beat you up." In a neighborhood, it is a neighbor threatening to do property damage if turned into the homeowner's board. At the office, a co-worker who knows some private personal information threatens to use it against another in exchange for a small fee. This type of blackmail has some sort of physical or tangible harm attached.
Emotional BlackmailThis is a bit different.
The threat is not tangible, rather it is emotional. Susan Forward and Diane Frazier (Forward and Frazier, 1997), coined the acronym FOG (fear, obligation, and guilt) to describe the three main emotions a blackmailer uses against a victim. Because the threat is not tangible, the villain can easily claim no responsibility. Their logic is that if the victim did not feel fear, obligation, or guilt then they wouldn't be able to blackmail them. The
target gives into the demand because they don't want to experience the negative emotion. This is often cyclical and can build in intensity as the threats are effective.
