Mind Meld: Skeptics & Believers Unite!
Can believers and skeptics collaborate to test psychic abilities?
Imagine two scientists who fundamentally disagree about psychic abilities deciding to test the same phenomenon together — but separately. Marilyn Schlitz, who believes in psychic effects, and Richard Wiseman, a well-known skeptic, conducted identical experiments where they tried to mentally influence people's skin conductance from a distance. In their first two studies, something remarkable happened: Schlitz consistently got positive results while Wiseman got nothing. But when they tried a third time with tighter controls, the pattern vanished entirely.
Joint believer-skeptic experiments found no evidence for remote mental influence.
Marilyn Schlitz, a researcher who believes in psychic abilities, teamed up with Richard Wiseman, a well-known skeptic, to conduct joint experiments testing whether people can mentally influence others at a distance. Their collaboration aimed to bridge the divide between believers and skeptics in parapsychology research. This unusual partnership represented a rare attempt at truly collaborative science in a highly controversial field.
When believers and skeptics conduct identical experiments, they can get dramatically different results — but the reasons remain hotly debated.
Key Findings
- The third experiment failed to replicate their previous findings - neither the believer nor the skeptic produced any significant effects on participants' skin conductance.
- This left them with two possible explanations: either their initial positive results were due to chance or subtle experimental flaws, or some aspect of the new study design disrupted a genuine psychic effect that had occurred in the earlier experiments.
What Is This About?
The researchers conducted experiments where each investigator separately attempted to mentally influence the skin conductance (a measure of emotional arousal) of participants located in a distant room. In their first two studies, they found an intriguing pattern: when Schlitz (the believer) conducted the experiments, participants showed significant changes in skin conductance, but when Wiseman (the skeptic) ran the same procedures, no effects occurred. For their third study, they designed a more controlled experiment to test whether this 'experimenter effect' would replicate and to explore possible explanations for the different outcomes.
Researchers tested whether investigators could mentally influence the skin conductance of distant participants, with both a believer and skeptic conducting separate experiments.
The third collaborative experiment found no evidence for remote mental influence, failing to replicate earlier positive results that had shown experimenter effects.
How Good Is the Evidence?
The study involved three separate experiments over multiple years, with the final replication attempt showing no effects - a common pattern in parapsychology where initial promising results often fail to replicate in subsequent studies.
Supporters argue that the experimenter effects in the first two studies suggest genuine psychic phenomena that may be sensitive to experimental conditions or researcher attitudes. Skeptics contend that the failure to replicate in the third, more controlled study indicates the initial results were likely due to chance, experimental artifacts, or unconscious bias. Both sides agree that collaborative research between believers and skeptics represents a valuable approach to studying controversial phenomena. The mixed results highlight the challenge of establishing reliable effects in parapsychology research.
Mainstream: The failed replication confirms that apparent psychic effects are likely due to experimental flaws, chance, or bias rather than genuine phenomena. Moderate: The experimenter effects suggest that researcher attitudes and expectations may influence results in ways not yet understood, warranting further investigation. Frontier: The initial positive results indicate genuine psychic abilities that may be disrupted by overly rigid experimental conditions or skeptical attitudes.
Many people think parapsychology research is unscientific, but this study shows researchers using rigorous experimental controls and honest reporting of negative results - the hallmarks of good science.
To settle this question would require multiple independent laboratories successfully replicating the remote influence effect under strictly controlled, pre-registered conditions with adequate sample sizes and proper blinding. This study meets some criteria by involving collaboration between skeptic and proponent researchers, but the failure to replicate previous findings and lack of detailed methodology reporting limit its conclusiveness.
The new study failed to replicate our previous findings and the results obtained in the present study accurately reflect the absence of a remote detection of staring effect.
Stance: Skeptical
What Does It Mean?
The idea that a researcher's beliefs might literally influence their experimental results challenges our basic assumptions about objective scientific measurement. This collaboration between natural opponents in the field represents a fascinating experiment in the sociology of science itself.
It's like when you feel someone staring at you from across a room - this study tested whether such feelings might be real by measuring physical responses when people tried to mentally 'reach out' to others at a distance.
If experimenter effects in parapsychology research are genuine, it could suggest that the researcher's beliefs or expectations somehow influence the outcome of experiments in ways we don't yet understand. This might point to subtle psychological or even physical mechanisms that affect sensitive measurements. Alternatively, it could reveal how unconscious biases shape research in ways that are difficult to detect even with careful controls.
This study demonstrates the importance of replication in science - even when initial results seem promising, they must be independently confirmed before being accepted as reliable evidence.
