Primitive Mentality


Conservative caveman. Just kidding, he isn’t actually disgusted, because his lip doesn’t curl back to resist the (simulation of) bad food that would be approaching his mouth.

“People who are easily disgusted by body odours are also drawn to authoritarian political leaders.”

That’s what the article says. Well, that’s what the scientist hypothesizes. And his explanation is pretty convincing – if you’re extra sensitive to the smells of sweat or urine, you may be more supportive of the dictator type of political leader who “puts people in their places,” because that type of leader reduces contact between different groups of people (i.e., divides people) which decreases anyone’s chance of becoming ill.

Say that again? The further around you turn your head when you smell [other people’s smells] the more you appreciate a political leader that makes sure you don’t have to smell “other” people.

Usually, I take smell-in-the-news with a grain of salt. Reason being, smell is too misunderstood of a sense to make groundbreaking discoveries in psychology by way of its perceptual channel. Usually also, I take behavioral /social psychology in the news with another grain of salt. The reason for that is the replication crisis in psychology (particularly social psychology, similar to behavioral psychology).

That being said, Jonas Olofsson of Stockholm University has an interesting idea. Disgust is a powerful emotion, and one that can, or should, be easily tested via smell. A little etymology digression – disgust comes from gustation which is about taste and eating and satiation, and to figure out what’s good to eat is one of the few main reasons why we smell, or so it seems. That natural behavior of determining what’s good to eat extrapolates into all kinds of other behaviors, one of them possibly being who to vote for.

Psychological theories about disgust and (American) conservativism have been around for quite some time, but this is a different approach. Check it out for yourself and see what you think.

Avian Navigation

Pigeons were fitted with mini Ticka watch cameras in 1908 by Dr Julius Neubronner to take aerial photos.

Researchers from the universities of Oxford, Barcelona and Pisa temporarily removed seabirds' sense of smell before tracking their movements. … They found the birds could navigate normally over land, but appeared to lose their bearings over the sea. … This suggests that they use a map of smells to find their way when there are no visual cues.

Is there ever such thing as an animal that doesn’t use smell to navigate? Or anything for that matter? Humans use smell to “navigate.” We find the nipple by smell. We find mates by smell. (This is one of the few things about “pheromones” that’s unequivocally evidenced – it’s not the pheromones, and besides we don’t have pheromone receptors, but we do tend to like smells from people with compatible immune systems.) I really love how Alexandra Horowitz, in her book Being A Dog, describes the dog actively mapping its environment by its smells. I like how pet detectives find your escaped cat by drizzling your own urine outside your apartment complex so they have a point of familiarity to home-in on. And how could you not love this Florida woman who bottled her own scent so she could be found later as an Alzheimer’s wanderer.
