The nose knows, says Lyall Watson, and in Jacobson's Organ, he sets out to prove that a humble, often overlooked set of nasal pits helps us decide whom to hit on, and whom to hit. First identified in 1811 by Danish anatomist Ludwig Levin Jacobson, the vomeronasal organ has been implicated in the reception of pheromones, those ephemeral chemical signals animals use to communicate nonverbally.

Watson organizes his thesis around the seven broad classes of smells identified by pioneering naturalist Carolus Linnaeus: floral, goatish, musky, foul, nauseating, spicy, and garlicky. In each section, Watson presents evidence of a surprising and unacknowledged role of smell and pheromones in human life. Is it possible that first impressions are the result of chemical signals? Watson thinks so, and also that pair-bonding, fistfights, love of offspring, and memories may have more to do with our humble nose than we think. In what is bound to be one of his more controversial stretches, Watson implicates nasal plastic surgery in postoperative mood changes:

Every time a surgeon slices away at a nasal septum in the name of fashion or vanity, both sides of Jacobson's organ are at risk of being damaged or even removed entirely, without thought for the consequences.... If you are considering cosmetic surgery on your nose, know that it could deprive you of the very things in life which having a new, cute, little button nose were supposed to improve.

Jacobson's Organ is full of Watson's pithy opinions and conjectures. Some are supported by science, some are not. But as we learn more about the role of the vomeronasal structures in human chemical communication, it becomes clear that a nosey approach is nothing to sneeze at. --Therese Littleton --This text refers to an out of print or unavailable edition of this title.

There's little doubt that smell plays a significant role in the lives of humans. Watson (Beyond Supernature), like many before him, argues convincingly that odors are superb at rekindling lost memories. He is also in good company when he asserts that some smells and some pheromones often have consequential but unconscious effects on humans. Beyond rehashing what has become widely accepted, Watson attempts to discuss the importance of Jacobson's Organ, the "unconscious partner to the nose." Jacobson's Organ, also called the vomeronasal organ, consists of two small pits in front of the nasal septum with nerves feeding directly to the most primitive, limbic area of the brain. Scientists believe that the vomeronasal organ in humans, as in reptiles, can sense large molecules that have no impact on our ordinary sense of smell. Watson claims that it is "a chemical clearing house for subliminal impressions, for... bad vibes, warm fuzzies, instant dislikes and irresistible attractions. Just the sort of will-o'-the-wisps with which any decent sixth sense ought to be concerned." Perhaps there is a sixth sense mediated by Jacobson's Organ. The problem, however, is that Watson spends virtually all of his time providing eclectic information on the traditional sense of smell, only alluding to Jacobson's Organ. Only in his final chapter does he focus on it directly; and there, to his credit, he writes, "everything that follows here is pure speculation on my behalf." As with his earlier work, Watson provides tantalizing conjectures, but his uncritical acceptance of the paranormal reduces his credibility. (Apr.)
