Smell Preferences Largely Hard-Wired in Brain

DolceTracker| Scientists believe they have disproven the notion that smell preferences are personal and culture-driven. Researchers at the Weizmann Institute have ‘trained’ an electronic system to achieve a human-like level of predictability on smell preferences.

Smell preferences, say researchers, are primarily hard-wired in our brains, and individualized within a comparatively narrow range of smell attributes. The findings are important for the burgeoning marketing science of sense technology — or transmitting scent digitally. via Science Daily
