Why is mesmerism viewed as unscientific today?

Mesmerism is viewed as unscientific today primarily because it lacks empirical support and reproducibility, key tenets of modern scientific inquiry. The theories proposed by Franz Mesmer, such as the existence of "animal magnetism," have not been substantiated by rigorous experimental evidence. Additionally, the psychological effects observed during mesmerism can often be attributed to suggestion and placebo rather than any mystical force, further distancing it from scientific credibility. Consequently, mesmerism has largely been dismissed by the scientific community in favor of evidence-based approaches in psychology and medicine.
