The Intention Experiment: Use Your Thoughts to Change the World. Lynne McTaggart

Several of the central figures in quantum physics argued that the universe was democratic and participatory – a joint effort between observer and observed.5

      The observer effect in quantum experimentation gives rise to another heretical notion: that living consciousness is somehow central to this process of transforming the unconstructed quantum world into something resembling everyday reality. It suggests not only that the observer brings the observed into being, but also that nothing in the universe exists as an actual ‘thing’ independently of our perception of it.

      It implies that observation – the very involvement of consciousness – gets the jelly to set.

      It implies that reality is not fixed, but fluid, or mutable, and hence possibly open to influence.

      The idea that consciousness creates and possibly even affects the physical universe also challenges our current scientific view of consciousness, which developed from the theories of the seventeenth-century philosopher René Descartes – mind is separate and somehow different from matter – and eventually embraced the notion that consciousness is entirely generated by the brain and remains locked up in the skull.

      Most modern workaday physicists shrug their shoulders over this central conundrum: that big things are separate, but the tiny building blocks they are made up of are in instant and ceaseless communication with each other. For half a century, physicists have accepted, as though it makes perfect sense, that an electron behaving one way subatomically somehow transmutes into ‘classical’ (that is, Newtonian) behaviour once it realizes it is part of a larger whole.

      In the main, scientists have stopped caring about the troublesome questions posed by quantum physics, and left unanswered by its earliest pioneers. Quantum theory works mathematically. It offers a highly successful recipe for dealing with the subatomic world. It helped to build atomic bombs and lasers, and to deconstruct the nature of the sun’s radiation. Today’s physicists have forgotten about the observer effect. They content themselves with their elegant equations and await the formulation of unified Theory of Everything or the discovery of a few more dimensions beyond the ones that ordinary humans perceive, which they hope will somehow pull together all these contradictory findings into one centralized theory.

Thirty years ago, while the rest of the scientific community carried on by rote, a small band of frontier scientists at prestigious universities around the globe paused to consider the metaphysical implications of the Copenhagen Interpretation and the observer effect.6 If matter was mutable, and consciousness made matter a set something, it seemed likely that consciousness might also be able to nudge things in a particular direction.

Their investigations boiled down to a simple question: if the act of attention affected physical matter, what was the effect of intention – of deliberately attempting to make a change? In our act of participation as an observer in the quantum world, we might be not only creators, but also influencers.7

They began designing and carrying out experiments, testing what they gave the unwieldy label of ‘directed remote mental influence’ or ‘psychokinesis’, or, in shorthand, ‘intention’ or even ‘intentionality’. A textbook definition of intention characterizes it as ‘a purposeful plan to perform an action, which will lead to a desired outcome’,8 unlike a desire, which means simply focusing on an outcome, without a purposeful plan of how to achieve it. An intention was directed at the intender’s own actions; it required some sort of reasoning; it required a commitment to do the intended deed. Intention implied purposefulness: an understanding of a plan of action and a planned satisfactory result. Marilyn Schlitz, vice-president for research and education at the Institute of Noetic Sciences and one of the scientists engaged in the earliest investigations of remote influence, defined intention as ‘the projection of awareness, with purpose and efficacy, toward some object or outcome’.9 To influence physical matter, they believed, thought had to be highly motivated and targeted.

      In a series of remarkable experiments, these scientists provided evidence that thinking certain directed thoughts could affect one’s own body, inanimate objects and virtually all manner of living things, from single-celled organisms to human beings. Two of the major figures in this tiny subgroup were former dean of engineering Robert Jahn at the Princeton Anomalies Engineering Research (PEAR) laboratory at Princeton University and his colleague Brenda Dunne, who together created a sophisticated, scholarly research programme grounded in hard science. Over 25 years, Jahn and Dunne led what became a massive international effort to quantify what is referred to as ‘micro-psychokinesis’, the effect of mind on random-event generators (REGs), which perform the electronic, twenty-first century equivalent of a toss of a coin.

      The output of these machines (the computerized equivalent of heads or tails) was controlled by a randomly alternating frequency of positive and negative pulses. Because their activity was utterly random, they produced ‘heads’ and ‘tails’ each roughly 50 per cent of the time, according to the laws of probability. The most common configuration of the REG experiments was a computer screen randomly alternating two attractive images – say, of cowboys and Indians. Participants in the studies would be placed in front of the computers and asked to try to influence the machine to produce more of one image – more cowboys, say – then to focus on producing more images of Indians, and then to try not to influence the machine in either direction.

Over the course of more than two and a half million trials Jahn and Dunne decisively demonstrated that human intention can influence these electronic devices in the specified direction,10 and their results were replicated independently by 68 investigators.11

While PEAR concentrated on the effect of mind on inanimate objects and processes, many other scientists experimented with the effect of intention on living things. A diverse number of researchers demonstrated that human intention can affect an enormous variety of living systems: bacteria, yeast, algae, lice, chicks, mice, gerbils, rats, cats and dogs.12 A number of these experiments have also been carried out with human targets; intention has been shown to affect many biological processes within the receiver, including gross motor movements and those in the heart, the eye, the brain and the respiratory system.

Animals themselves proved capable of acts of effective intention. In one ingenious study by René Peoc’h of the Fondation ODIER in Nantes, France, a robotic ‘mother hen’, constructed from a moveable random-event generator, was ‘imprinted’ on a group of baby chicks soon after birth. The robot was placed outside the chicks’ cage, where it moved around freely, as its path was tracked and recorded. Eventually, it was clear that the robot was moving towards the chicks two and a half times more often than it would ordinarily; the ‘inferred intention’ of the chicks – their desire to be close to their mother – appeared to affect the robot, drawing it closer to the cage. In over 80 similar studies, in which a lighted candle was placed on a movable REG, baby chicks kept in the dark, finding the light comforting, managed to influence the robot to spend more time than normal in the vicinity of their cage.13

The largest and most persuasive body of research has been amassed by William Braud, a psychologist and the research director of the Mind Science Foundation in San Antonio, Texas, and, later, the Institute of Transpersonal Psychology. Braud and his colleagues demonstrated that human thoughts can affect the direction in which fish swim, the movement of other animals such as gerbils, and the breakdown of cells in the laboratory.14

Braud also designed some
