Writing in 2011 for the Carleton College website, geophysicist Kim Kastens in a column with her daughter at first found the notion of lie-to-children as surprising. Kastens delved further into the issue, and identified specific instances where a lie-to-children teaching technique would do more harm than good for students. The worst examples included a lie-to-children which would later have to be unlearned following teaching from subsequent professors, an instance where the student is successfully able to identify the factual inaccuracy and knows more about it than the teacher, and using the technique without having a "master plan" involving progressive learning. In her 2011 book "The Children's Bill of Emotional Rights", Eileen Johnson discussed the lies told by parents to their children during the formation of childhood fictional mythology and pointed out the inherent problems this could raise in the future during the parenting process. Johnson cautioned: "Why do we tell these lies to children? At some point we have to admit we were lying. Parents are not sure how much of this deceit is right, how far to go with it, and how and when to explain it was all a lie."
