When Deception Becomes Ethical
Understanding Emma Levine’s Research on Lies, Harm, and Human Connection
Most of us grow up hearing the same moral rule: “Always tell the truth.” Yet, real life is messier. We soften feedback to protect someone’s feelings. We hide our disappointment to avoid hurting a friend. We offer hope to someone who is struggling, even when the future is uncertain.
University of Chicago Booth professor Emma Levine studies this tension between honesty and benevolence. Her research reveals something surprising: people often believe deception is not only acceptable, but ethical, when it prevents unnecessary harm.
Her work challenges the idea that lying is always wrong. Instead, she shows that deception can serve a high social good when used thoughtfully, sparingly, and with prosocial intent.
People Want Honesty, Except When They Don’t
In her landmark paper Community Standards of Deception, Levine demonstrates that people routinely endorse deception when it protects others from harm they see as unnecessary or avoidable.
This includes both:
Lies of commission: actively stating something untrue
and
Lies of omission: withholding information, softening details, or strategically avoiding disclosure
Her research shows that people don’t simply tolerate these lies; they often prefer them when the truth would inflict needless pain.
“Community Standards” That Govern Ethical Deception
Levine identifies implicit rules that guide when people believe deception is appropriate. They revolve around:
Who is being deceived e.g., vulnerable individuals, loved ones
What the topic is e.g., sensitive personal matters
When the conversation occurs e.g., moments of crisis or emotional fragility
Across these standards, one principle dominates: deception is ethical when it prevents unnecessary harm.
This helps explain why people often lie to comfort the grieving, encourage the discouraged, or protect the anxious.
Prosocial Lies: When Kindness Conflicts with Honesty
Levine’s broader body of work explores prosocial lies, deceptions intended to help rather than manipulate. These include:
Telling a friend their presentation was “great” when it was merely adequate
Offering optimism to a patient facing a difficult diagnosis
Pretending not to notice someone’s mistake to spare embarrassment
Her research shows that people frequently misjudge how harmful honesty will be and underestimate how much others appreciate gentle deception.
In many cases, because the recipient interprets the lie as an act of care, the “kind lie” strengthens trust rather than eroding it.
Lies of Omission: The Quiet Side of Ethical Deception
Not all deception involves saying something false. Often, it involves not saying something true.
Levine’s work shows that lies of omission can be just as ethically motivated as lies of commission. For example:
A doctor may withhold grim statistical details to preserve a patient’s hope
A manager may soften feedback to avoid demoralizing an employee
A parent may avoid sharing adult worries with a child
In these cases, omission serves a protective function, shielding someone from harm they cannot meaningfully act upon.
The High Social Good Standard
Across her research, Levine highlights a consistent criterion: deception is ethically acceptable when it serves a high social good. This includes:
Preventing unnecessary emotional harm
Preserving hope or motivation
Maintaining social harmony
Protecting vulnerable individuals
Importantly, this does not justify self‑serving lies. Deception is only ethical when the benefit flows to the other person, not the liar.
Why This Matters for Everyday Communication
Levine’s work helps us understand why communication is so fraught:
We value honesty, but we also value kindness.
We want to protect others, but we fear being dishonest.
We assume truth is always best, yet we routinely act otherwise.
Her research gives language to these contradictions and shows that ethical communication is not a binary choice between truth and lies. It is a nuanced balancing act between honesty and benevolence, accuracy and compassion, transparency and care.
A More Human Standard for Truth
While Levine’s work does not encourage lying, it does argue that ethical communication requires more than rigid adherence to truth-telling. It requires sensitivity to context, emotional intelligence, and a willingness to prioritize human well‑being.
Sometimes, the truth heals. Sometimes, the truth harms, and sometimes, a carefully chosen deception, whether spoken or withheld, is the most humane choice available.
Her research invites us to rethink honesty not as an absolute moral commandment, but as one value among many in the complex landscape of human relationships.
