Sensing the Sending of SMS Messages: An Automated Test
📄 Original study📌 Appears in:
Plain English Summary
Researchers built a fully automated system where a computer randomly picked one of your three contacts to text you, and you guessed who sent it before the message arrived. Across 886 trials, people guessed right 37.9% -- above the 33.3% chance rate and statistically significant. The effect was smaller than phone and email telepathy studies, possibly because nobody was supervising. Five top scorers retested on camera still hit an impressive 44.2%. As the first fully automated, experimenter-free telepathy test, it became a key stepping stone for later large-scale reviews.
Research Notes
Key bridge between supervised telephone/email studies and later meta-analyses. First fully automated, experimenter-free test in this paradigm. Cited in Liu (2023) meta-analysis and Sheldrake et al. (2025) telecommunication telepathy synthesis. Unsupervised design raises cheating concerns but filmed subset showed no evidence of fraud.
Automated online experiment testing telepathy with SMS messages. 886 trials with participants aged 11-72; computer randomly selected one of three contacts to send a message, subject guessed sender before receiving message. Overall hit rate was 37.9% (336/886), significantly above 33.3% chance (p=.001, d=0.10). Incomplete tests showed 38.4% hit rate, ruling out optional stopping. Five high-scoring subjects retested under filmed conditions: 44.2% (19/43, p=.09). Effect size smaller than telephone (d=0.45) and email (d=0.50) telepathy experiments, attributed to unsupervised design and asynchronous timing.
