Today's onslaught of entertaining suggestions change the minds of adults as well as children. The two studies below show the power of the imagination to distort reality and create false memories in people of all ages:

“When adults vividly imagine the occurrence of events that took place in their childhood, they become increasingly confident that these incidents actually happened to them. This phenomenon has been called imagination inflation [IEE]. This study assessed the imagination-inflation effect in 94 college students (mean age 21 yrs).”[3] (Journal of Psychology. 1999)

"This study seeks not only to replicate what has been called the imagination inflation effect (IIE) in 2 samples (98 undergraduates [mean age 19 yrs] and 106 middle-aged [mean age 46.9 yrs] factory workers) but also to identify individual difference variables that could predict susceptibility to suggestibility. The 2 experiments tested the extent to which locus of control for reinforcement, dissociability, and a hostile/self-controlling introject (self-concept) could predict the IIE. Results indicate that: IIE is a robust and replicable phenomenon with young adults—.”[4] ( Applied Cognitive Psychology. 1998)
Confirming the persuasive "role of imagination in effecting spiritual transformation," a third study concluded that:

“Spiritual transformation... is mediated through a person's religious imagination. This study was designed to explore, describe and illustrate the central role of the imagination in effecting and sustaining spiritual transformation—. The author espouses a holistic approach to spiritual direction so Jungian active imagination and various types of body work were employed as ancillary methods of accessing the imagination and eliciting spiritually transformative images.” [5] (Humanities & Social Sciences. 1998)
Ponder the words, "accessing the imagination and eliciting spiritually transformative images." They describe the effective power of the Harry Potter experience and the D&D role-playing games. Those "transformative images", in turn, can change beliefs and behavior. Meanwhile parents wonder why their children have turned their backs to the Bible, church and God.
