People’s sense of smell is just as sharp as those of rats and dogs, a researcher said recently, calling for an end to a century-old “myth” to the contrary. “For so long people failed to stop and question this claim, even people who study the sense of smell for a living,” he said. “It has been a long cultural belief that in order to be a reasonable or rational person, you could not be dominated by a sense of smell,” McGann said. Different sensitivitiesThe difference between humans, dogs and rodents when it comes to sense of smell may come down to different sensitivities to certain odours. “We are capable of tracking odour trails, and our behavioural and affective states are influenced by our sense of smell,” McGann wrote.
