Interesting question to see any effects on the scale of pheromone interactions. The hardest part of contextualizing these results would be to talk about them at the right scale. Think about how often people interact with others and pheromones are significantly perceivable. Think about other modalities that reign over these chemical signals, such as visual and auditory modalities. If my vision and hearing are the things that I rely the most because of frequency and ease of use, then pheromones might only significant at specific scales. There is information in those chemical signals, and maybe because we don't rely on them in the same way we might rely on language and other information, it might have limitations to how we interpret that information and how much exposure is needed to understand those signals in social interactions.
