Can measurements be physically conditioned by thought? Further observations following a focused intention experiment.

Background The biofield is a controversial concept among the scientific community. Some aspects of this phenomenon relate to measurable factors of mainstream science such as electromagnetics, while others, involving nonlocal interventions, intention, and consciousness, seem to produce physical changes through mechanisms that are still unknown, making the outcomes of many studies not fully explained by our current state of scientific understanding. This study explored the hypothetical effects of intention on the conditioning of a pH system with continuous data acquisition for real-time measurements. As a follow-up study, those effects were related to changes in the physicochemical properties of water samples chosen as a target in a previous large-scale intervention of focused intention. Methods The intention experiments were conducted under controlled conditions from the 8th to September 11, 2015. During this period, 286 qualified biofield therapy practitioners meditated at a distance with the intention of changing the vibrational state of the water molecules contained in specific flasks. Several variables were evaluated, including the magnetic field and ultraviolet-visible (UV-VIS) radiation from 175 to 954 nm near the experimental spot, as well as Raman spectra, pH, and electrical conductivity of all the water samples. After this period, real-time pH measurements of water samples were taken with the same equipment and under the same experimental conditions, except for the practitioners' awareness of those experiments, and without their focused intention. Real-time pH, electrical conductivity and the concentration of cations and anions measured by ion chromatography in the water samples were used to test the proposed hypothesis. Results Real-time pH was responsive during the intention experiments and after this period. Further continuous measurements performed after the 11th September showed that the pH variations overtime kept a systematic and consistent tendency similar to the one observed during the experimental activities involving focused intention. After the replacement of the electrode internal electrolyte, this behavior was no longer verified, and the pH was stable as the initial tests to evaluate the equipment sensitivity. Conclusions After the experimental period involving focused intention, the pH system maintained a systematic and consistent behavior while measuring the pH of new water samples. An eventual intention-mediated conditioning of the pH measurement system occurred because of changes in the properties of the electrode internal electrolyte.
