Human olfactory capabilities are often underestimated, challenging the notion that our sense of smell is significantly inferior to other species. Contrary to popular belief, olfactory receptors may not be as scarce as stated in textbooks. A prominent figure in neuroscience suggests that about 50% of medical textbook content may be inaccurate, resulting in consequences that are incalculable for patient treatment today. This underlines the need for continual questioning and reassessment of established knowledge in medicine and science.
