- Parodied in Darths & Droids when Mon Mothma (who is a Valley Girl for some reason) says "Our best spy, Wedge, died to bring us this information." Wedge points out that actually, he didn't and she replies "Oh! Wedge, I totally didn't recognize you. Love your hair."
- Star Wars vs Warhammer 40K: Hondo Onaka mentions to the Jedi in Episode 10 that he lost more men on the mission to infiltrate Axum and gather intelligence on the Imperial occupation than he has on any other job.

- Under Ten Flags. Admiral Russell isn't happy about the lack of progress by British intelligence in getting hold of a German naval code.

- A number of James Bond's allies have sacrificed their lives getting crucial information to British intelligence.

- In Heralds of Valdemar, Ylsa is killed while smuggling incriminating information. She dies before reaching her superiors, but gets close enough that her magically-gifted comrades can sense what's going on and teleport the message where it needs to go. The usurpers her killers were working for are executed the very next day.
- Invoked in Babylon 5: Sheridan orders the Rangers to leak some information to the Shadows. However he is concerned that they won't believe it unless someone was...

- In Star Trek: Deep Space Nine, Sisko and Garak hatch a plan to bring the Romulans into the war against the Dominion. One of Garak's contacts forges a data rod showing the Dominion leaders planning to invade Romulus, and Garak suggests Sisko tell a Romulan senator people died retrieving the data. The senator sees through the forgery, but Garak assassinates him and implicates the Dominion, which was his back-up plan the whole time.
- Played for Laughs in the Saturday Night Live skit The Chosen One. The Chosen One is the Idiot Hero Chad; to highlight how dumb and careless he is, seconds after someone gives him a map that thousands of Centauri died for, he lets it slip through his fingers and blow away.

- Shepard recruits Tali in Mass Effect 2 after rescuing her from an important surveying mission gone south. Tali's entire squad (aside from herself and possibly one other soldier) is lost getting the data, which concerns a star destabilizing much faster than it ought to be.

Tali: That damn data had better be worth it.
