AI Chatbots vs Abavuzi Bantu

Early mental health chatbots such as Woebot and Wysa were largely scripted. They guided users through cognitive behavioral therapy (CBT) exercises using pre-written responses, which made them predictable but limited. Newer tools use large language models, which respond more flexibly but less predictably. Many people also use general-purpose chatbots for emotional support, even though these were never designed or tested as therapy. The research is mixed. Randomized trials and meta-analyses of chatbot interventions generally report small-to-moderate short-term reductions in depression and anxiety symptoms. Follow-up periods are often short, many users drop out and comparison groups vary. In 2025, Dartmouth researchers published a randomized trial of Therabot, a generative AI chatbot built for therapy, in NEJM AI. It reported symptom reductions compared with a waitlist, which is a weaker comparison than active treatment by a human. The therapeutic alliance, meaning the bond, agreement on goals and agreement on tasks between client and therapist, is one of the most consistent predictors of outcome in human therapy. Some chatbot studies report that users rate their sense of bond with the bot fairly high. Whether that feeling works the way a human alliance does, including repairing ruptures and challenging the client, is not established. The risks are well documented. In 2023 the National Eating Disorders Association took down its Tessa chatbot after it gave weight-loss advice. Research testing chatbots with crisis scenarios has found missed or inappropriate responses to suicidal statements. Lawsuits have alleged that companion and general chatbots contributed to teenagers' suicides. Chatbots also tend to agree with users, which can reinforce distorted beliefs. Human therapists are licensed and accountable, and they can assess risk, arrange emergency care and coordinate treatment. A common misconception is that it has to be one or the other. The most defensible use is chatbots alongside human care, not instead of it. Some states, including Illinois in 2025, have passed laws restricting AI from providing therapy.
