This test is based on Sensory Processing Sensitivity — a well-documented temperament trait most widely studied by psychologist Dr. Elaine Aron, found in roughly 15–20% of people (and in over 100 other species). It measures how deeply your nervous system processes incoming stimulation across three dimensions: how easily you become overwhelmed by demands and multitasking, how strongly you respond to beauty and subtle detail, and how sensitive your body is to physical stimulation like noise, light, and texture.
Unlike a lot of sensitivity content that treats it as a single yes-or-no label, your results give you a full breakdown across all three dimensions, plus a genuine, in-depth profile — not just a score, but what it actually looks like in your relationships, your work, and your day-to-day life.
