The law of assumption is the belief, taught by the mystic Neville Goddard in the 1940s through the 1960s, that whatever you persistently assume to be true about yourself and your life will eventually show up in your experience. In practice it means choosing one wish, imagining it as already fulfilled (often while drowsy, as you fall asleep), and then acting and thinking as the person who has it.
There is no scientific evidence that an assumption changes outside events by itself. What does have research behind it is the human side of the practice: expectations shape effort, confidence changes performance, and rehearsing a plan helps people follow through.
What is the law of assumption?
The law of assumption is a manifestation philosophy built on one claim: your assumptions, meaning the things you quietly take for granted about yourself and your world, are the cause of your experience, not the result of it. Change the assumption, the teaching says, and your life reorganizes to match.
Followers describe a simple loop. You pick a desire. You imagine the moment it is true until it feels natural, not wished for. Then you persist in that new assumption, and you stop treating the old one (“I’m the person who never gets picked”) as a fact.
Key terms you will hear
- Assumption: a belief you hold without needing proof. In this teaching, an assumption is something you choose and keep choosing.
- Living from the end: imagining from the viewpoint of the wish already fulfilled, not from the viewpoint of someone waiting for it.
- State akin to sleep (SATS): a relaxed, drowsy state, just before sleep, used for imagining the wish fulfilled.
- Persistence: returning to the new assumption again and again, especially when your circumstances seem to argue with it.
- Revision: mentally replaying a day that went badly and rewriting it the way you wish it had gone.
- The 3D: online slang for your current physical reality, the “evidence” you can see right now.
If you are new to the wider idea, our guide to how to manifest gives the big picture, and does manifestation work? looks at the research without hype.
Where the law of assumption comes from
The idea traces to Neville Goddard (born 1905 in Barbados, died 1972 in California), a lecturer and author who taught in the United States for decades. His books include Your Faith Is Your Fortune (1941), Feeling Is the Secret (1944) and The Law and the Promise (1961).
Goddard summed up his method as assuming “the feeling of the wish fulfilled,” and he is often quoted as saying that an assumption, though false, if persisted in, will harden into fact. He taught that imagination is the creative force in a person, and he read the Bible as a book about states of mind. That religious framing is part of the original teaching, and it is something many modern followers leave out.
It is worth knowing that his biography is not without controversy. In 1929 an investigator working for Harry Houdini publicly challenged an early ministry of his, and his mystical claims are, by their nature, claims he made himself. That doesn’t make his techniques useless, but it is a reason to treat the teaching as a personal practice, not as established fact.
Today the law of assumption circulates widely in online manifestation communities, often described as a more direct cousin of the law of attraction. I couldn’t verify when or where the current wave of interest began, so take any “it went viral in year X” claim with care.
Short version: Goddard did not run experiments. The law of assumption is a spiritual teaching, and what follows below separates what the teaching claims from what psychology can actually support.
Law of assumption vs. law of attraction
The two get mixed up constantly, because both say that inner states shape outer life. The practical differences are about where the effort goes.
| Question | Law of assumption | Law of attraction |
|---|---|---|
| Main idea | Your assumptions about reality create your experience | Like attracts like: your energy draws matching experiences |
| Where you focus | Becoming the person who already has it | Raising your mood and sending out a clear request |
| Typical tools | SATS, mental scenes, affirmations, revision | Gratitude, visualization, vision boards, scripting |
| Attitude to doubt | Persist in the new assumption; doubt is an old habit | Release resistance; stay open and detached |
| Evidence | None that thoughts alone change outside events | The same |
Online, some people treat the two as rivals and others as the same thing. Both are belief systems, and both share the same honest limit: nothing shows that a thought can move the world without you moving too.
How to practice the law of assumption, step by step
This is the version most practitioners describe, with a few changes that make it easier to keep up and less likely to turn into self-pressure. Plan on about ten minutes the first time and five after that.
1. Pick one specific wish
Choose a single desire for now. “More confidence at work” is fine, and so is “an offer from the design team.” Vague wishes like “be happy” give your imagination nothing to hold.
2. Turn it into an assumption
Ask: what would I take for granted if this were already true? Write one sentence in the present tense. “I’m someone people trust with important projects.” Keep it believable enough that it doesn’t make you wince.
3. Find the scene
Choose one ordinary moment that only happens if the wish is true. Not the dramatic headline (“I got the job!”), but the quiet Tuesday afterward: opening your new laptop, telling a friend over coffee, walking to a different desk.
4. Rehearse it in a drowsy state
Lie down as you would for sleep. Breathe slowly. Put yourself in the scene as a participant, not a spectator: what do you see from your own eyes, what do you hear, what does your body feel like? Let the scene loop gently a few times as you drift off. Don’t force it, and don’t worry if you fall asleep halfway.
5. Live from the assumption during the day
Pick one action that fits your sentence. If you assumed “I’m someone people trust with important projects,” that could be volunteering for one visible task or asking a manager what a stretch assignment looks like. The point isn’t to fake anything. It’s to behave a little more like the person in your scene.
6. Return, don’t restart
When doubt shows up, and it will, you don’t need to start over. Repeat your sentence, recall the scene for thirty seconds and go on with your day.
7. Review weekly
Once a week, write down what you did, what changed and whether the sentence still fits. Adjust the wording, not the standard you hold yourself to.
How to word an assumption: before and after
A good assumption is short, present tense, about you and believable enough to repeat. Most first drafts need some work.
| First draft | Better assumption | Why it works |
|---|---|---|
| I will be rich someday. | I’m someone who manages money calmly and saves every month. | Describes a trait and a behavior you can show up as today. |
| He will text me back. | I’m someone who is easy to love and who chooses people who are kind and clear. | Focuses on you, not on another person’s decision. |
| I’m not nervous. | I’m steady when I speak, even if my heart is beating fast. | Positive wording, and honest about the body. |
| I got promoted. | My work is valued, and my manager and I talk openly about my next role. | Describes a situation you can picture without needing a lie. |
If a sentence feels false
Researchers found that repeating positive self-statements can backfire for people who already feel low about themselves (Wood and colleagues, 2009). If your sentence makes you feel worse, don’t push harder. Use a bridge: “I’m learning to…” or “I’m becoming someone who…”. That’s not a failure of the method. It is the method working with how your mind actually responds.
The state akin to sleep (SATS): a script you can use tonight
SATS is the signature technique of the law of assumption. The idea is that drowsiness lowers your mental chatter, so the scene feels less like pretending. Whether or not you accept the spiritual claims, a calm, pre-sleep rehearsal is a pleasant way to end the day.
A five-minute SATS script (read it once, then close your eyes)
Lie down, breathe in for four counts and out for six, three times. Let your shoulders sink.
Say your sentence once, silently: “I’m someone people trust with important projects.” Now step into one scene. It is a Tuesday morning and you are walking into the meeting room. Notice the light, the chair under your hand, who is sitting across from you.
Someone asks for your view. You answer in two clear sentences. Feel your shoulders stay low. Feel the small, quiet satisfaction of being asked. Say “thank you” in your head, and let the scene replay slowly, like a favorite song, until you drift off.
Tips for better rehearsal
- Keep the scene short enough to repeat, about 20 to 40 seconds.
- Use first-person view. If you see yourself from outside, step into your body.
- Include one line of dialogue, because spoken words make the scene feel real.
- Skip clock-watching. A rehearsal that stops at “I should be asleep by now” has become a worry.
For more on picturing scenes well, see the visualization guide and the scripting page, which covers writing the scene out as a short story.
Revision: rewriting a day that went badly
Revision is the second technique Goddard is known for. At night you replay the day that bothered you, then mentally edit it so it ends the way you would have wanted. You are not changing the past in any literal sense. You are choosing which version of the memory you fall asleep with.
Example
Say a coworker interrupted you in a meeting and you stayed silent. In bed, replay the moment. This time, you pause, smile slightly and say, “I’d like to finish my point.” They nod. Run the new version three or four times until it feels natural.
Psychologists wouldn’t call this magic, but the mechanism is familiar. Rehearsing a better response is a form of mental practice, and it helps you notice what you’d like to do next time.
Revision is for ordinary irritations. If a memory is traumatic or keeps intruding, don’t replay it alone at night. A therapist can help you work with it safely.
Law of assumption by goal: money, love, career and confidence
The method is the same each time. What changes is the sentence, the scene and the action.
Money
Assumption: “I’m someone who knows where my money goes and feels calm about it.” Scene: opening your banking app on payday and moving a set amount into savings. Action: schedule that transfer, review your spending once a week. Nothing here replaces a budget; the assumption simply keeps you showing up to it. If money is causing real strain, a nonprofit credit counselor can help you make a plan. See how to manifest money for more.
Love
Assumption: “I’m someone who is wanted and who chooses well.” Scene: an easy dinner with someone who is relaxed, curious and consistent. Action: say yes to one invitation a week. Keep the focus on your own life. The law of assumption does not give you power over another person’s feelings, and you shouldn’t try to use it that way (more in manifesting a specific person).
Career
Assumption: “I’m someone employers are glad to see.” Scene: the first day in a new role, or the moment a manager says your idea is worth trying. Action: send two tailored applications or ask for one conversation with someone in the field. The how to manifest a job guide has a full plan, and you can browse career affirmations for wording.
Confidence
Assumption: “I’m comfortable being seen.” Scene: introducing yourself at a gathering and feeling your breathing stay steady. Action: do one slightly uncomfortable thing each week. Our confidence affirmations are a good starting point.
What happens when reality disagrees: a troubleshooting guide
“I assumed it for weeks and nothing changed.”
That is a very common experience, and it is not proof that you did it wrong. Many goals depend on other people, timing and chance. Look at what you did in daily life and add one concrete action. If you can’t name one, that’s the gap.
“I feel like I’m lying to myself.”
Then your sentence is too far from where you are. Move to a bridge statement, and let the feeling of being believable guide you. A stretch is useful. A lie is not.
“Every time I see bad news, I feel like I’ve ruined it.”
This is the part of the online version that does the most harm. The idea that one doubtful thought cancels your progress has no support, and treating it as true leads to anxious self-monitoring. Thoughts pass through everyone’s mind. They do not break anything.
“I keep checking for signs.”
Checking is a form of worry in disguise. Set a rule: one review a week, and no scanning the rest of the time. If you want to understand why you notice more coincidences when you are looking for them, the page on signs your manifestation is coming explains how attention works.
What research says about assumptions, expectations and effort
There is no research showing that the law of assumption works as taught. But several well-studied ideas overlap with parts of it, and it helps to know which parts are supported.
Confidence can change performance
In studies by Lysann Damisch and colleagues (2010), students who believed they had a lucky charm or a lucky golf ball did better on a putting task and a memory game, and the researchers found the boost was explained by increased self-efficacy, a person’s confidence in their own ability. The samples were small (28 and 41 students in the two experiments I checked), but the idea is consistent: believing you can do something changes how hard you try.
Picturing only the good outcome can drain effort
Heather Kappes and Gabriele Oettingen (2011) found that people who imagined an idealized future felt less energized afterward. Earlier work by Oettingen, Pak and Schnetter (2001) found that imagining the future and the obstacle in the way produced commitment that matched people’s real expectations of success, while indulging in fantasy alone did not. This matters because the pure “assume it and it comes” version of the law of assumption skips the obstacle step.
If-then planning helps people act
A large meta-analysis by Peter Gollwitzer and Paschal Sheeran (2006) found that specific if-then plans help people reach goals. An example is “If it is 8 a.m. on Monday, then I send one application.” This is the part of your day that makes an assumption concrete.
The honest summary: assuming something does not change outside events by itself. But a steady, confident, well-planned person tends to act differently, and acting differently can change what happens next.
Criticisms and risks worth knowing
- Blame: if every outcome is a mirror of your mind, people in hard situations can end up blaming themselves. Real life includes luck, systems and other people’s choices.
- Avoiding action: assuming a wish is done can feel so good that you stop doing the work. See the Kappes and Oettingen research above.
- Self-gaslighting: telling yourself you are fine when you are not can delay you from seeking help.
- Unrealistic financial or health decisions: acting “as if” you have money you don’t have, or ignoring a symptom because you have decided you are healthy, can cause real harm.
- Obsession over another person: using the method to “assume” someone’s feelings can turn into checking and waiting, which is hard on both of you.
If you are dealing with persistent anxiety, low mood, financial hardship or a health concern, please talk to a doctor, a therapist or a financial counselor. A mindset practice can sit beside that help but should never stand in for it.
A simple week of law of assumption practice
Here is a gentle schedule you can copy. It takes about five minutes a day and includes exactly one real-world action.
Sample week (goal: a new role)
Monday: Write your assumption and choose your scene. Send one tailored application.
Tuesday: SATS at bedtime, with the scene on loop for a few minutes.
Wednesday: Revision for any rough moment from the day. Update your resume bullet points.
Thursday: SATS again. Message one person who works in the field.
Friday: Write three lines on what moved this week, big or small.
Sunday: Review. Is the sentence still believable? Edit it, and set next week’s one action.
If you want an app to carry some of this, Kaizen’s morning affirmations are written from your own journal, and the evening manifestation story is set in an ordinary day of the life you are building, which maps closely onto the “find the scene” step. A notebook works just as well. Our future self journaling guide covers a paper version.
Questions
What is the law of assumption?
The law of assumption is a manifestation belief, taught by Neville Goddard, that whatever you persistently assume to be true about yourself and your life will eventually appear in your experience. In practice it means imagining your wish as already fulfilled and acting as the person who has it. There is no scientific evidence that assumptions change outside events on their own.
Who created the law of assumption?
The law of assumption comes from Neville Goddard, a Barbados-born lecturer and author who taught in the United States and died in 1972. He described the idea in books such as Feeling Is the Secret (1944) and The Law and the Promise (1961). Modern online communities have adapted his ideas, so today’s versions often differ from his original teaching.
What is the difference between the law of assumption and the law of attraction?
The law of assumption focuses on assuming your wish is already true, while the law of attraction focuses on raising your mood and sending out matching energy. The tools overlap: both use visualization and affirmations. Neither has scientific evidence that thoughts alone change external events.
How do you practice the law of assumption?
To practice the law of assumption, choose one wish, write it as a present-tense sentence, then imagine one ordinary scene from the moment it is true, ideally while drowsy at bedtime. During the day, act in small ways that fit that sentence and revisit it when doubt appears. Add one concrete action each week so the practice leads somewhere.
What is SATS in the law of assumption?
SATS stands for state akin to sleep, a drowsy, relaxed state used for imagining your wish fulfilled. Practitioners lie down, breathe slowly and replay a short scene of the wish being true as they fall asleep. It is a bedtime rehearsal technique, and its spiritual claims are not scientifically supported.
What is revision in the law of assumption?
Revision is a technique in which you replay a day or moment that went badly and mentally rewrite it with the ending you would have wanted. It is done at night and repeated a few times. Psychologically, it works like mental rehearsal of a better response, and it is not meant for traumatic memories.
How long does the law of assumption take to work?
There is no reliable timeline, and no evidence it works on its own. Online claims range from days to months, but outcomes depend on your actions, other people and chance. Judge the practice by what you do and how you feel each week, not by a deadline.
Does the law of assumption really work?
No study shows that assuming something changes outside events by itself. The parts of the practice that overlap with psychology, such as building confidence, rehearsing scenes and planning specific actions, do have research support. Treat it as a way to focus attention and act with more confidence, not as a guarantee.
Can doubt ruin the law of assumption?
No, a doubtful thought cannot undo your progress, and believing it can leads to anxious self-monitoring. Doubt is a normal human reaction, especially when you want something badly. When it appears, repeat your sentence, recall your scene briefly and take your next real step.
Is the law of assumption safe?
It is generally low-risk as a bedtime imagination exercise, but it has pitfalls. Avoid acting as if you have money you don’t, ignoring health symptoms, or blaming yourself when things go wrong. If you are struggling with anxiety, mood, money or health, seek help from a professional alongside any mindset practice.
