Radical honesty

Radical honesty (RH) is casually referenced as, practicing complete honesty and refraining from telling even white lies. The phrase was trademarked in 1997 as a technique and self-improvement program based on the best-selling book "Radical Honesty" by Brad Blanton. Other authors have proposed similar ideas, such as Sam Harris, in his book "Lying", and Immanuel Kant, who claimed in his 1797 essay "On a Supposed Right to Tell Lies from Benevolent Motives" that we have a categorical imperative not to lie under any circumstance, not even to a murderer looking for their victim. While these and other proponents of Radical Honesty present the practice as a moral imperative, Blanton's programs argue against moralism and promote Radical Honesty as a means for reducing stress, deepening connections with others, and reducing reactivity . 
In popular culture.
The character Eli Loker, played by Brendan Hines, from the 2009 Fox series "Lie to Me" adheres to Radical Honesty during the first season. From the website bio of the character in the first season: “Eli Loker is Lightman's lead researcher, who is so uncomfortable with the human tendency to lie that he's decided to practice what he calls "radical honesty." He says everything on his mind at all times and often pays the price.” <ref name="www.fox.com/lietome/characters/brendan.htm"></ref>

At a Moth Mainstage event in 2009, radio producer and writer Starlee Kine related her experience with Radical Honesty, which she labelled a cult. Kine described a seminar where Blanton was verbally abusive and at one point urged her to sign a contract to obey him completely for the duration of the seminar.<ref name="http://feeds.themoth.org/~r/themothpodcast/~5/UYpZuVelQ9c/moth-podcast-110-starlee-kine.mp3"></ref>
In the last book of the "Uglies" series by Scott Westerfeld, a character named Frizz Mizuno invented a surgical brain procedure called "Radical Honesty" that renders him unable to lie. In fact, if he hears someone tell a lie when he himself knows the truth, he can't even simply "not" speak—he has to reveal the truth under any circumstances. Even at the possible cost of his own life and the lives of people he cares about, he still can't lie to save them, because his brain is "wired" to speak the truth.
In "Bones" (season 6), episode 20, "The Pinocchio in the Planter", the victim, Ross Dickson, was part of a fictional group called "The Honesty Policy" that practiced Radical Honesty. The episode begins exploring radical honesty as the victim being deliberately rude and belligerent, with ill effects potentially leading to his demise, and with a crass and alienating character who attended the same group. However, it also explores through several character sub-plots positive outcomes resulting from honesty inspired by encountering the concept of Radical Honesty. The phrase "Radical Honesty" is used throughout the episode.
In "Silicon Valley" (season 5), episode 3, "Chief Operating Officer", a character called Ben Burkhardt played by Benjamin Koldyke follows a leadership philosophy developed by Kim Scott called "Radical Candor" or as he calls "RadCan" which bears many of the hallmarks of a warped version of Radical Honesty. e.g., for comedy purposes, he is 'honest about lying' and withholding information from other characters when speaking with third parties. Thereby drawing those third parties into his 'honest' (at least to the third party) lies.
