Affirmations and visualisation: what the evidence says

Affirmations and visualisation cover several different practices. Repeating a positive sentence, reflecting on personal values and mentally rehearsing an action serve different purposes and have different research behind them.

None provides a basis for promising that a wish will come true. Start by naming what you want to prepare: a conversation, decision, work session or response to a mistake.

What research says about positive statements

In two experiments reported by Wood and colleagues in 2009, participants with low self-esteem felt worse after repeating a prescribed positive statement or focusing on its truth than in comparison conditions. These findings concern particular experiments; they do not establish that all supportive language is harmful. Read the positive self-statements study.

If a sentence creates strong internal disagreement, you do not need to repeat it more forcefully. You could describe an available action instead: “I will prepare one example and clarify the question I cannot answer yet.” That wording does not require pretending the outcome is already secured.

Why self-affirmation is a different research term

Cohen and Sherman's 2014 review describes self-affirmation interventions that often involve writing about important personal values. That evidence cannot automatically support claims about repeating “I am successful.” Read the review of self-affirmation research.

If thoroughness matters to you, an everyday question might be “Which source needs checking before I send this report?” If relationships matter, you might ask “How can I agree on a convenient time to talk?” These are our editorial examples of connecting a value with an action, rather than a reproduction of a research intervention.

Decide what you are mentally rehearsing

Pham and Taylor's 1999 study compared simulations of exam preparation and the desired exam outcome among college freshmen. Process simulation improved studying and grades. That result should not be assumed to apply to every goal and setting. Read the original mental-simulation study.

Before a work meeting, you could consider your opening question, which figures to have available and how to ask for time to check an answer. A vivid image of success is optional: you can write the same preparation in words or talk it through.

Connect an outcome with an obstacle and a plan

A 2021 meta-analysis by Wang, Wang and Gai combined 21 studies of mental contrasting with implementation intentions: considering a desired future alongside obstacles and making if–then plans. The average effect on goal attainment was small to moderate, with possible overestimation from publication bias. This concerns a combined strategy, not positive fantasy alone. Read the MCII meta-analysis.

For a proposal, an example might be:

• Outcome: send a clear first draft for discussion
• Obstacle: I start formatting before deciding what to say
• Plan: if I open design templates, I will first write the problem, proposal and one example in a plain document

If the obstacle is missing information or another person's decision, record that dependency and agree on how to get an answer. Not every barrier is under your control.

Review a specific result

After trying the exercise, check the task: is there a draft, a clarified question or an agreed next action? A successful attempt does not establish why it worked. If the exercise creates pressure, you can adapt it or stop.

First distinguish the outcome from the action with our guide to goals, projects and tasks. To examine a sweeping conclusion, use the guide to balanced thinking. For conversation preparation, continue with exercises for confident action.
