High sensitivity (HSP) — a temperament trait, not a weakness

"Don't take everything so personally", "you are oversensitive" — highly sensitive people hear this all their lives. Yet the research of Elaine and Arthur Aron (1997) showed that high sensitivity is neither a choice nor a character flaw but a measurable temperament trait: sensory-processing sensitivity (SPS), present in roughly 20–30% of the population — and not only the human one, as a similar processing strategy has been found in over a hundred species.

The four pillars of high sensitivity

Researchers describe it with the acronym DOES: Depth of processing (analysing experiences more thoroughly than others), Overstimulation (faster overload from noise, crowds, task pile-ups), Emotional reactivity (stronger emotional responses and empathy), Sensing the subtle (catching nuances others miss).

A double-edged trait

The same nervous system that overloads faster brings real advantages: highly sensitive people catch errors and nuances better, experience art and nature more deeply, listen attentively and are often conscientious workers. Research on "differential susceptibility" shows something even more interesting: sensitive people respond more strongly not only to bad but also to good environments — in supportive conditions they flourish more than others.

How to live with it well

The key is designing your environment, not fighting the trait: recovery buffers after intense days, controlling the stimulus dose (headphones, breaks, less multitasking), stating boundaries directly, and choosing roles where depth of processing is an asset. The HSP test shows how strongly the trait is expressed in you — the first step to stop blaming yourself for what is simply the architecture of your nervous system.
