The feeling of being a fraud despite outward success.


Imposter syndrome is that nagging feeling that you've fooled everyone into thinking you're competent, and you're about to be 'found out.' If you've ever felt this way, you're not alone. This experience, known as the impostor phenomenon, is incredibly common among high-achievers. The struggle isn’t a lack of competence — it’s feeling unworthy of it.


In this post, I’ll provide you with five science-backed strategies to help you:

  • Recognise the key signs of imposter syndrome

  • Understand why it shows up

  • Implement practical, evidence-based steps to silence self-doubt

  • Lead with authentic confidence


I’m Diane Thompson of Courage Over Comfort Coaching, and I work with senior leaders and high-potential women who are ready to break out of self-doubt and step fully into their influence.



What is Imposter Syndrome? The Definition and Its Impact


Originally coined in 1978 by Pauline R. Clance and Suzanne A. Imes, the imposter phenomenon describes persistent feelings of self-doubt and the fear of being exposed as a “fraud,” even when there is clear evidence of success and competence.

For example: you’ve been promoted, you’ve delivered results, your peers praise you - yet inside you’re thinking, “They must have got it wrong. I don’t really belong here.”


Why this matters:

  • It undermines your confidence, making you undervalue your impact.

  • It causes you to over-work, over-prepare, avoid delegation and burn out. [Asana]

  • It holds you back from authentic leadership, risk-taking, and stepping into your full voice.



What Are the 5 Types of Imposter Syndrome?


According to expert research, there are five “types” or profiles of imposter-feelers.

Recognising yours is the first step to accelerating change.


  1. The Perfectionist – Focuses on how things are done. Any flaw = failure.

  2. The Expert – Measures competence by what they know or how quickly they learn. If they don’t know something – “I’m a fraud.”

  3. The Soloist – Believes “I must do it alone.” Asking for help = exposing weakness.

  4. The Natural Genius – Believes you should effortlessly succeed. If you struggle, you feel like a fake.

  5. The Super-Person – Juggles many roles (leader, parent, mentor, partner) and expects to excel in all. Falling short in any role means failure.


Take a moment: which of these profiles feels most like you? Becoming aware is your first powerful shift.



How to Overcome Imposter Syndrome: 5 Science-Backed Strategies


Here are five evidence-based strategies to move you from stuck in “fraud mode” to stepping into your power with authenticity and impact.


  1. Separate Feelings from Facts.

    The Science: Cognitive-behavioural principles show that our thoughts are not always facts. Those feelings of “I don’t belong” are real — but they’re not evidence. Research shows many high-achievers experience imposter feelings despite strong, objective performance metrics.

    Your Strategy: When the “fraud” voice speaks up, pause and ask: “What is the objective evidence for and against this thought?” Write down the factual evidence of your success.


  2. Reframe Your Inner Rule-Book.

    The Science: Psychologists note that people with imposter syndrome often have rigid, unconscious "competence rules" (e.g., "I must never ask for help"). These create impossible standards and perpetual anxiety.

    Your Strategy: Identify one of your own internal rules. Then, consciously re-write it to be realistic and compassionate. Example: Change “I must know everything” to “I have the capacity to learn what I need to succeed.”


  3. Normalise the Experience Through Sharing.

    The Science: Studies on social sharing and self-disclosure indicate that bringing hidden fears into the light reduces their power. Sharing your experience dissipates the isolation and shame that fuel imposter feelings.

    Your Strategy: Choose a trusted peer or mentor and share: “One thing I’m proud of is X, and one thing I’m figuring out is Y.” You’ll likely find they have similar experiences.


  4. Document and Attribute Your Wins Accurately.

    The Science: Those with imposter syndrome often attribute success to external factors like luck, while internalising failure. The act of writing down achievements builds a new, evidence-based narrative of competence.

    Your Strategy: Keep a weekly "Win Log." Write down two specific achievements and the skill, effort, or perseverance you contributed to make them happen.


  5. Embrace Strategic Imperfection.

    The Science: Perfectionism is a core driver of imposter syndrome. Behavioural experiments show that deliberately submitting "good enough" work (instead of perfect) and observing that the outcomes are still positive can systematically dismantle the fear of failure.

    Your Strategy: Identify one low-stakes task this week and intentionally deliver it at 85% of your perceived capacity. Notice what happens. Did the world end? Was the result still valuable? This builds evidence against the need for perfection.
