Even as artificial intelligence becomes more advanced in simulating care and concern, people still place greater emotional value on support they believe comes from a fellow human. A new study has found that when people receive the exact same message but are told it was written by a person rather than an AI chatbot, they experience the message as significantly more empathic, supportive and emotionally helpful. The findings were published in the journal Nature Human Behaviour.
The research involved over 6,000 participants who shared emotional stories and received responses generated by a large language model. In each case, the response was identical, but half were told it came from an AI and the other half believed it was from a human. Across multiple studies, participants consistently rated the human-attributed messages as more genuine, caring and emotionally resonant.
Even more telling was the fact that people were willing to wait days (or even weeks) for a human response rather than receive an instant message from an AI. This preference was strongest when the participants were seeking emotional connection, such as feeling understood or cared for. The study also revealed that people were more likely to feel positive and less likely to feel negative emotions after reading messages they thought came from a human.
Interestingly, the content of the message was less important than who people believed wrote it. Messages that focused on understanding alone were not rated as more or less empathic depending on whether they came from a human or AI. But when the response included emotional sharing or expressed care, people responded far more positively if they thought a human had written it.
This finding has serious implications for the use of AI in mental health support, counselling and other emotionally sensitive areas. While AI chatbots can now mimic empathy with impressive fluency, this study suggests they may never fully replace the human touch in moments of distress or vulnerability. In fact, just knowing that AI might have helped compose a message reduces its perceived emotional value.
The researchers suggest that this comes down to a belief that true empathy involves effort, emotional investment and shared human experience—qualities people do not associate with machines. No matter how convincing the message may be, people seem to sense that AI cannot genuinely care.
This does not mean AI has no role in emotional support. The study’s participants still found value in AI responses, especially when quick answers were needed or when people were reluctant to share their thoughts with another person. But when it comes to feeling truly heard, understood and emotionally connected, people overwhelmingly prefer other people.
Even in an increasingly digital world, the study shows that human empathy still holds a unique and irreplaceable value.
