The idea of death is ingrained in our human nature, and the way we depict it is also connected to the scene of a dead animal, human, bird, or fly. Therefore, what is the connection between all of them that we had not previously considered? The odor.
The human nose is capable of sensing a wide range of smells, but it cannot classify them but is still reacting to them, according to current research. such as the scent produced by the putrescine chemical. This is a chemical that the body makes when it starts to decay. One important fact to know is that the animal’s scent is the result of its necrophobic behavior over time, which is thought to have evolved at least 420 million years ago.
It is thought that the smell of putrescine causes the animals to feel threatened in two different ways: the response that a hunter is close by, and the second is that they have been set in life peril, so their sense advises them to get away.
To demonstrate that human reactions and behavior are identical to those of animals, researchers have carried out four distinct experiments on humans using a mixture of putrescine, water, and ammonia.
Vigilance In the first experiment, participants were subjected to the odor of putrescine and asked to demonstrate their vigilance when confronted with it. The results showed that people who were exposed to the smell of putrescine were much more alert than people who were exposed to ammonia and water.
Behavior in escape The second test was conducted by the researchers, who asked an unsuspecting group of people to rate the intensity, repugnance, and familiarity of the scent. The researchers wanted to know how the group responded to the smells and how quickly the participants would walk away from them at a distance of 80 meters. People who smelled the putrescine were more likely to leave the area quickly, indicating that the smell provided a compelling reason to flee.
A word stem-completion task was given to the participants in a subsequent experiment, shortly after the group was given the scent of putrescine.
The findings indicate that the group was motivated to complete the word stems by the smell of putrescine, all of which were associated with escape and other associations with the word escape. The use of thread words was also elevated by the smell.
Hostility and defensiveness In the final experiment, the participants were exposed to a decent scent that they were unable to detect. They were given a text to study in this experiment, and their job was to evaluate the author.
The participants were defensive and hostile toward the author because they were unable to detect the subtle smell of putrescine. This also demonstrated that participants’ defensive behavior was triggered by unintentional exposure to the odor.
