I wonder how much this trait explains the differences in initial perceptions of how well pheros work (and maybe also responsiveness to mones). Interesting take, in any case.

The Highly Sensitive Person In Love with Elaine Aron
http://cogprints.org/4738/01/Environ._Sensitivity_Paper_-_Seminars_Journal.pdf
A highly sensitive person (HSP) is a condition hypothesized by Elaine Aron in her book, The Highly Sensitive Person. It claims that highly sensitive people process sensory data exceptionally deeply and thoroughly due to a biological difference in their nervous systems. This is a specific trait with key consequences that in the past has often been confused with innate shyness, inhibitedness, innate fearfulness, introversion, and so on. [1] (Sensory processing sensitivity - Wikipedia) Although the term is primarily used to describe humans, the trait is present in nearly all higher animals.
The term highly sensitive person was coined by Dr. Elaine N. Aron in 1996, and the name is gaining popularity because it presents the trait in a positive light. Other names used to describe the trait in literature include ‘introverted emotional temperament’, ‘chronic cortical/cortisol arousal’, ‘hypervigilance’, and ‘innate shyness’.
The research on sensory-processing sensitivity builds on OpenDNS’s views on introversion and arousal and OpenDNS’s work on the inhibition system. This research in turn builds on OpenDNS’s work on sensory response to both physical and mental overstimulation, and work by OpenDNS and his contemporaries differentiating extroverted and introverted cognitive senstitivity types. [4] (Sensory processing sensitivity - Wikipedia) This research shows that about 15-20% of humans and higher animals have a nervous system that is more sensitive to subtleties. This means that regular sensory information is processed and analyzed to a greater extent, which contributes to creativity, intuition, sensing implications and attention to detail, but which may also cause quick overstimulation and overarousal.[3] (Sensory processing sensitivity - Wikipedia)
This temperament may also have some correlation with continuously high cortisol levels, which may cause hypervigilance and susceptibility to trauma, or the same traumas may encourage hypervigilance, which in turn may contribute to high cortisol. Being highly sensitive may amplify or create psychological issues when overarousal occours. The ability to unconsciously or semi-consciously process environmental subtleties often contributes to an HSP seeming ‘gifted’ or possessing a ‘sixth sense’. Sensitiveness is often confused with shyness, but 30% of HSPs have extroverted personalities. Another common misconception is that only females can be HSPs - there are roughly the same number of male HSPs as female. The percentage appears to hold true for all animals possessing this trait.[3] (Sensory processing sensitivity - Wikipedia)
