While truthfulness is a cornerstone of relationships, dementia care can create ethical conflicts where protecting a loved one from distress or greater harm, like institutionalization, outweighs a rigid adherence to the truth. "Therapeutic lying" can become a necessary, though difficult, tool for compassionate caregiving.

People believe it's ethical to lie about a negative trait if the person cannot change it. In a study, 64% endorsed lying about an uncontrollable stutter, but only 19% would lie if it was due to controllable nerves. Feedback is reserved for what's changeable.

People are far more willing to lie to someone in a vulnerable state. In a study, only 3% would lie to an underperforming employee, but that number jumped to nearly 20% if the employee's father had just been hospitalized.

Thomas Mueller-Borja views honesty as selfishly practical, as dishonesty is energetically draining. However, he places kindness higher in his value hierarchy. In situations of tension, choosing the kind path may trump absolute honesty, especially when recognizing that everyone holds their own version of the truth.

Speakers use omission as a moral compromise between a hurtful truth and a direct lie. However, listeners perceive this avoidance and feel they've been denied both honesty and the benevolence of a kind lie, making omission feel worse than either alternative.

Some truths, like telling new parents their baby is ugly, are considered 'bad truths.' They cause significant emotional pain without leading to any learning or positive change, making it a situation where a lie is morally preferable.

When someone tells a pro-social lie to protect feelings, the recipient may trust their intentions more (benevolence-based trust) but trust the literal truth of their statements less (integrity-based trust), creating a complex dynamic in the relationship.

A lie intended to be benevolent backfires when the recipient believes the withheld information was necessary. The host's mother lied about COVID exposure to avoid stress, but it was seen as a paternalistic betrayal because the host felt the information was critical.

People are more effective at deceiving others about their true motivations when they first deceive themselves. Genuinely believing your own pro-social justification for a self-interested act makes the act more compelling and convincing to others.
