What does ESP mean?
Extrasensory perception, or ESP, refers to a claimed ability to obtain information beyond the recognized senses. It is a claim about where information comes from, not simply a name for a strong feeling. Recognizing a familiar pattern or reading someone’s expression can be impressive without being extrasensory.
To investigate a hidden-information claim, first specify the information that should be unavailable. A vague feeling is difficult to score; a choice among four symbols is more concrete.
Why the hidden part matters
If a target is visible in a reflection, signaled by a friend’s expression, or selected in a predictable pattern, a match could have an ordinary explanation. Confidence does not rule out those possibilities.
The exercise below chooses a random target sequence before your answers. Targets stay hidden until you complete the test and unlock your results. Because it runs in your browser, it is an informal activity, not a tamper-proof research instrument.
Choose the scoring rule first
In this activity a symbol either matches exactly or it does not. A star does not become “close enough” to a circle after the reveal. Clear rules keep a surprising outcome from changing the meaning of the earlier guess.
There are 20 trials and four equally likely targets. Five matches is the chance average, with variation around it. One session cannot establish ESP.
A better follow-up question
Instead of asking only “Was I right?”, ask “Did I follow the rules I chose before seeing the answer?” That habit makes future observations easier to interpret. Keep the whole record, including misses, and resist repeating only until you like the result.
