Humans’ sense of smell is actually just as strong as dogs, but people dull their senses with carcinogenic artificial fragrance
(Natural News) A groundbreaking study from Rutgers University-New Brunswick debunks a 19th century myth that humans’ sense of smell is inferior to dogs and other rodents. Neuroscientist John McGann, associate professor in the Department of Psychology, School of Arts and Sciences, says that humans can discriminate maybe one trillion different odors. Researchers previously believed that humans were only capable of distinguishing about 10,000 different odors. For 150 years this misconception was held dear and perpetuated by entry-level psychology textbooks.
