Emotional contagion
People automatically mimic others' expressions and posture, which can produce matching feelings within seconds.
Never tested separately
Clairsentience is the claimed ability of receiving information as a physical sensation rather than an image. It has never been tested as a distinct ability.
Clairsentience, or "clear feeling", is described as sensing information through physical sensations and emotions: a heaviness entering a room, chills near a certain place, or suddenly feeling someone else's pain or mood. People who identify with it often describe being overwhelmed in crowds.
The word belongs to the "clair" family used in spiritualist and New Age writing, alongside clairvoyance and clairaudience, and it became common in popular psychic literature in the late twentieth century. Unlike clairvoyance and telepathy, it has not been isolated as a separate subject of controlled experiments.
The experiment
The "clair" terms multiply by sensory channel — sight, hearing, feeling, knowing — but the experiments only ever measure the answer. The distinction lives entirely in the report, not in the result.
A twentieth-century addition to the "clair" family, built by analogy with clairvoyance rather than from any separate tradition.
People automatically mimic others' expressions and posture, which can produce matching feelings within seconds.
The body registers tension, temperature and smell before they reach awareness, and the result arrives as a "feeling".
Knowing a place has a history — a hospital, a battlefield — primes the body to react.
Visit places or handle objects chosen by someone else, without being told their history, and record your impressions before you learn it. Compare against a friend with no claimed ability doing the same.
