Appendix K — Émile Coué: Suggestion, And The Early Psychology Of Hope
In the early decades of the twentieth century, long before neuroscience, cognitive behavioural therapy, or the scientific study of placebo and nocebo effects had become established fields, a quiet French pharmacist named Émile Coué began drawing public attention to something both simple and controversial: the possibility that the human mind plays a powerful role in shaping human experience.
Today, ideas such as positive thinking, affirmations, expectation, self-talk, and mindset are deeply woven into modern culture. Entire industries have been built around them. Some are thoughtful and evidence-based; others drift into exaggerated promises and simplistic optimism. Yet more than a century ago, Coué stood near the beginning of this movement, attempting to understand — in practical rather than mystical terms — how belief, imagination, and repeated suggestion influence human behaviour and wellbeing.
He did not invent hypnosis, suggestion, or the idea of mind-body interaction. Those traditions stretched back through mesmerism, hypnotism, philosophy, religion, and medicine. But Coué helped move these ideas away from mystical explanation and toward practical psychology, placing emphasis on observation, repetition, expectation, and the subconscious influence of thought.
Born in Troyes, France, in 1857, Coué initially planned to study analytical chemistry but switched to pharmacy. His professional training mattered: unlike many nineteenthcentury spiritual healers, he worked in a field defined by preparation, dosage, observation, and measurable outcomes. Pharmacists occupied a distinctive place between medicine and the public—dispensing remedies while observing how ordinary patients responded over time.
While working as an apothecary, Coué noticed what later medical research would confirm: treatments often appeared more effective when patients believed they would help. He found that offering medicines with encouragement and confidence—reassuring patients they were likely to improve—frequently produced better responses. What began as anecdote gradually formed a clear pattern: the treatment itself mattered, but so did the patient’s expectation. That insight became central to his later work.
Between 1886 and 1887 he studied hypnotism in Nancy with AmbroiseAuguste Liébeault and Hippolyte Bernheim, leaders of what later became known as the Nancy School of Suggestion and Hypnotism. In 1910 he sold his business and retired to Nancy, where he opened a clinic that provided around 40,000 treatment sessions per year for the next sixteen years; many patients were treated in groups and received care free of charge.
Modern research now recognizes that expectation can alter pain perception, anxiety, mood, stress responses, and even measurable physiology. Placebo research shows that factors such as pill colour, practitioner authority, clinic atmosphere, and the confidence surrounding a treatment influence patient experience: larger tablets often elicit stronger placebo effects than smaller ones, injections can seem more potent than pills, and expensive-appearing treatments can outperform cheaper equivalents even when active ingredients are identical.
The practitioner also becomes part of the treatment itself.
A calm, confident doctor can reassure and regulate anxiety. A fearful or dismissive one can increase distress. Modern medicine refers to the harmful influence of negative expectation as the nocebo effect.
Coué recognized many of these dynamics long before modern scientific terminology existed to describe them.
Yet unlike contemporary scientific trials, which attempt to remove expectation in order to isolate the pure chemical effect of a treatment, Coué moved in the opposite direction. Rather than eliminating suggestion, he explored how suggestion itself might assist healing.
Importantly, however, he did not see this as mystical power.
One of the most striking aspects of Coué’s writing is his repeated rejection of the role of miracle healer. Again and again, he insisted:
“I cure nobody.”
“There is no healer here.”
“The power is in you.”
These statements are historically significant because Coué lived during a transitional period between nineteenth-century mesmerism and modern psychology. Earlier figures such as Franz Anton Mesmer had proposed invisible magnetic forces flowing through the body, while hypnotism often carried theatrical or occult overtones involving trances, pendulums, magnetic passes, or dramatic demonstrations.
Coué increasingly distanced himself from these traditions.
Although he still used repetition, rhythm, atmosphere, and suggestion, he believed the essential mechanism was not magnetic force but the human imagination itself.
His most famous principle was simple:
“When the imagination and the will are in conflict, the imagination always wins.”
In practical terms, Coué observed that people often strengthened the very experiences they wished to avoid. Someone saying, “I must not fail,” mentally rehearses failure. A person terrified of insomnia becomes increasingly focused on wakefulness. Fear, expectation, and emotional anticipation begin shaping behaviour and physical responses.
According to Coué, the subconscious mind responds more strongly to repeated emotional ideas than to forceful acts of willpower.
From this came his method of conscious autosuggestion — the deliberate repetition of simple, rhythmic phrases intended to influence thought patterns and emotional expectation.
His best-known affirmation became famous around the world:
“Every day, in every way, I am getting better and better.”
Coué instructed people to repeat the phrase multiple times daily, often using a knotted string to keep count. To modern readers this can appear ritualistic or simplistic, and indeed many critics mocked the method during the 1920s. Newspapers caricatured “Couéism” as naïve optimism or magical thinking. Some patients reported improvements that later faded. Others failed to improve at all.
These criticisms are important and should not be ignored.
Coué occasionally attracted followers who exaggerated his work into claims of miraculous healing, despite his own repeated efforts to avoid such interpretations. Some contemporary observers believed enthusiasm surrounding the movement sometimes outpaced the evidence supporting it. Certain medical claims made during the period now appear medically outdated, overly optimistic, or impossible to verify reliably.
Yet dismissing Coué entirely because of these limitations would also overlook something historically important.
What Coué recognized — long before modern psychology fully matured — was that expectation, repetition, emotional framing, and belief influence human experience in powerful ways.
Modern research into placebo effects, cognitive therapy, stress physiology, predictive processing, and psychosomatic medicine increasingly supports the idea that the brain actively shapes how people perceive pain, stress, fear, recovery, and emotional wellbeing.
Coué lacked the scientific tools to explain these mechanisms fully, but many of his observations now appear remarkably perceptive.
Historical context also matters enormously.
Coué’s rise occurred during and immediately after World War I, one of the most psychologically devastating events in modern European history. Millions of young men died in the trenches. Vast numbers returned physically injured, emotionally shattered, or burdened with what would later become recognised as trauma-related disorders. At the time, terms such as “shell shock,” “nervous collapse,” and “neurasthenia” were commonly used to describe severe emotional and psychological suffering.
Reading Coué’s testimonials within this historical setting changes the tone considerably.
The letters repeatedly speak of exhaustion, grief, hopelessness, nervous suffering, insomnia, chronic fear, despair, and emotional collapse. Europe itself was traumatised. In many respects, Coué’s work can be understood as part of a broader search for psychological recovery and emotional stability after years of catastrophe.
This helps explain why his message resonated so deeply during the 1920s.
He offered people not simply optimism, but a sense of personal agency at a time when much of the world felt emotionally broken.
It is also important to recognize that Coué did not advocate abandoning medicine altogether. Although some later followers drifted toward exaggerated interpretations, Coué himself repeatedly encouraged patients to continue appropriate medical care. His interest lay not in replacing medicine, but in understanding how thought, expectation, confidence, and imagination influenced human functioning alongside physical treatment.
This balance matters historically.
Coué was neither a modern neuroscientist nor merely a mystical faith healer. He occupied a transitional space between medicine, psychology, hypnosis, and human observation. He stood at a moment when scientific medicine was advancing rapidly, yet many physicians still underestimated the emotional and psychological dimensions of illness and recovery.
In this sense, Coué helped prepare the ground for later developments in psychology, psychotherapy, hypnotherapy, placebo research, and cognitive approaches to mental health.
His influence also extended into the historical foundations of modern hypnosis and subconscious suggestion. Joane Goulding, who studied hypnosis extensively and developed the Goulding System decades later, was familiar with Coué’s work and regarded him as an important historical influence alongside figures such as Mesmer and James Braid.
Yet the Goulding System is not a replication of Coué’s method.
Coué primarily taught adults to influence themselves through conscious autosuggestion. Joane Goulding’s work emerged from a very different situation: a mother attempting to reach her daughter Michelle during periods when normal daytime communication was limited. What Joane discovered was that gentle, loving communication delivered during the early stages of sleep could still reach the subconscious mind even when conscious engagement was difficult.
The similarities between the two approaches are therefore structural rather than identical.
Both recognized:
the influence of repetition,
the importance of emotional atmosphere,
the role of expectation,
the power of calm rhythmic language,
and the responsiveness of the subconscious mind.
But the Goulding System differs fundamentally in tone and purpose. It is not a clinical protocol based on self-directed autosuggestion. It is a parent-child process grounded in attachment, emotional safety, consistency, and love.
As Joane Goulding later reflected:
“Our approach echoed Coué’s ideas. But ours was not a clinic protocol. It was a family response, guided by love and disciplined hope.”
That distinction is important.
Coué helped popularize the idea that repeated thought and suggestion influence human experience. Joane Goulding adapted related principles into a uniquely child-centred system focused not on willpower or self-improvement, but on helping children feel emotionally safe, accepted, and loved.
Perhaps this is why Coué still feels unexpectedly modern today.
Not because every claim associated with his movement proved correct.
Not because affirmations alone solve complex problems.
And not because he discovered some magical secret of the mind.
Rather, his importance lies in recognising — earlier than many others — that the human mind is not a passive observer of experience. Hope, expectation, fear, repetition, emotional environment, and internal dialogue all influence how people respond to life.
Modern science continues exploring these questions today.
More than a century later, Émile Coué remains historically important not as a miracle worker, but as one of the early figures who helped move the discussion of suggestion, belief, and subconscious influence away from mysticism and toward practical human psychology.
