Paternalistic deception
Paternalistic deception is deception that is apparently performed for the deceived individual's own good by a person assuming a paternalistic role, whether they are their actual parent or not. It is justified by the good it attempts to produce towards the deceived individual's well-being. An example of paternalistic deception would be a doctor telling a parent that their child is doing well, even though they know that they are going to die. The doctor acted paternalistically to spare the parent's feelings.
