Joseph Murphy’s affirmations, checked against the research

What did Murphy mean by an affirmation?

For Murphy, an affirmation states that something is already true, so that the subconscious, in his model, takes it in and acts on it. The theory sits in chapter 2 of The Power of Your Subconscious Mind (1963): “Your subconscious mind does not argue with you. It accepts what your conscious mind decrees.”

Affirming is everywhere in the book. In a transcription of the 1963 text, a text search on 20 October 2026 found about 62 words beginning with “affirm” and 22 uses of “over and over”; the counts are approximate, because the transcription comes from scanned pages. Chapter 6 gives the method its own heading, “The Affirmative Method”, and a few pages earlier, under “The Baudoin Technique” (his spelling), borrows a formula from Charles Baudouin: sum the idea up in a brief phrase and repeat it “over and over again as a lullaby” in a drowsy state.

Murphy adds a caveat that is often forgotten. Quoting the Gospel’s warning against “vain repetition”, he says an affirmation works through your understanding of what the words mean, not through the words themselves. He then asks you to hold the statement as true whatever the evidence against it. That second instruction is where the research parts company with him.

Where Murphy’s affirmations come from

The repeated phrase did not start with Murphy. In the 1922 American edition of Émile Coué’s Self-Mastery Through Conscious Autosuggestion, the formula reads “Day by day, in every way, I am getting better and better”, to be said 20 times morning and evening, counted on a string with 20 knots. Murphy cites Coué in chapter 8 and presents him as a famous French psychologist; Coué (1857–1926) was in fact a pharmacist in Troyes before running his practice in Nancy.

Murphy’s own formulas are of the same kind: a single word repeated before sleep, a morning line (“I choose happiness today”, in chapter 15), the instruction never to say “I can’t”. What he added was the theology: in his books, the statement works because the subconscious is one with what he calls Infinite Intelligence.

What happens when people repeat a positive statement about themselves?

In 2009, the psychologists Wood, Perunovic and Lee published one survey and two experiments in Psychological Science. In the first experiment, university students either repeated the statement “I’m a lovable person” or did not; in the second, they focused either on how it was true of them or on how it was both true and not true. The researchers then measured their mood and state self-esteem, how they felt about themselves in that moment.

Among people with low self-esteem, those who repeated the statement or focused on how it was true “felt worse” than those in the comparison conditions. Among people with high self-esteem, the same instructions left them feeling better, “but to a limited degree”, in the authors’ words. Self-esteem moderated the effect: the same sentence helped some people a little and set others back.

The limits are real: student samples, one sentence, mood measured in a single session. The authors’ explanation fits a plain intuition: a statement far from what you already believe about yourself tends to be rejected, and can bring the contrary thoughts to mind. Low self-esteem participants fared better when they were also allowed to note how the statement was not true. Murphy’s advice to hold the statement against all evidence asks the hardest thing of exactly the people for whom that distance is widest.

“Self-affirmation” in psychology is something else

The term causes confusion. In social psychology, self-affirmation theory goes back to Claude Steele’s 1988 chapter. The exercises built on it do not repeat a positive sentence: as Geoffrey Cohen and David Sherman’s 2014 review puts it, they “typically have people write about core personal values.”

That review reports benefits for “education, health, and relationship outcomes” that “sometimes persist for months and years.” Then came a stricter test. The writing exercise had been offered as a way to narrow racial achievement gaps at school, and in a school setting where an earlier large field experiment had shown positive effects, Hanselman and colleagues (2017) ran a well-powered replication with the same procedures. They found “no evidence of effects”, with estimates precise enough to “reject benefits larger than an effect size of 0.10”, and wrote of the “potential fragility of self-affirmation in educational settings when implemented widely.”

Rewriting a Murphy-style affirmation so it holds

The fix is not to drop the sentence but to shrink it until the inner voice lets it pass, and to point it at something you do. The left column quotes lines from Murphy’s chapters; the last row keeps his line as it is, because it already names a choice rather than a fact.

Where an affirmation lives in Dream Architect

Each dream on the Dreams page has a field called Deep belief, under “Belief, status, delete”, with the placeholder “Write the belief you want to live from.” The line then appears on that dream’s own page, opened by “View timeline”.

If you turn on “Reminders of your moment” in Settings (in a web browser, “Reminders while the app is open”), the line of your current dream also appears in those short reminders, as “Belief: …”, at an interval of 5, 10, 15 or 30 minutes. These are the closest the app comes to Murphy’s repetition, and they are off until you choose them.

The night ritual, “Picture your dream”, does not repeat the line. It asks for a moment instead: “Write my own moment” comes with the hint “A few words, in the present tense.” At the end, when you tap “I close my eyes”, the screen goes dark and shows that moment with “It’s real.” and the feeling you chose. That is the app’s one nod to Murphy’s present tense, and it is read once, as a scene, not repeated as a claim about yourself. These details come from the app’s content on 20 October 2026.

A fair verdict on Murphy’s affirmations

Murphy was right that short, repeated, present-tense language is easy to carry, and right that understanding matters more than parroting. His belief that the subconscious accepts any decree and turns it into events is not supported by any of the research above, and his advice to hold a line against all evidence is the part most likely to backfire.

What survives is modest and usable: write one line you can say without wincing, about what you are doing or learning, and pair it with a scene and a next step rather than repeating it until it feels true.
