How to Eliminate Self-Doubt Forever & Build Unshakeable Confidence
Episode of The Mel Robbins Podcast · May 11, 2026 · 1 h 19 min
Mel Robbins talks with behavioral researcher Dr. Shadé Zahrai about her four-part framework—acceptance, agency, autonomy, adaptability—for overcoming self-doubt and building confidence.
Summary
Mel Robbins hosted Dr. Shadé Zahrai, a behavioral researcher and author of the book Big Trust, to discuss the sources of self-doubt and a research-based framework for building confidence. Zahrai described her own childhood experience of performing for family, which she said instilled a belief that she was only worthy when pleasing others, and cited Robert Kleck's Dartmouth scar experiment as an illustration of expectation bias. Using a ping pong ball and golf ball in glasses of water, she argued that the goal is not to eliminate doubt but to keep it from sinking into one's self-image.
Zahrai then laid out four attributes. For self-acceptance, she described patterns such as the pressure to prove, the likability trap, shrinking syndrome and the schadenfreude cycle, and recommended a care-less/care-more list, replacing apologies with appreciation, delaying yes, taking up hobbies, and using growth-oriented statements rather than positive affirmations, which she said can backfire for people with low self-esteem. For agency, she discussed impostor phenomenon, social comparison and over-preparation, telling the story of designer Paula Scher's Citi logo. For autonomy, she addressed overthinking, complaining and blame, recommending scheduled worry time and replacing "should" with "could."
For adaptability, Zahrai presented the opposite action strategy from dialectical behavior therapy and research on neck flexion, which Robbins summarized as "lift the chin, let's begin." She also covered diaphragmatic voice, a pen-in-teeth enunciation exercise, a humanness-versus-courage matrix for teams, and career imprinting, which Robbins connected to her early work as a public defender. Zahrai closed with Elizabeth Gilbert's story of lowering her standards while writing Eat, Pray, Love and urged listeners to show up now rather than wait to feel ready.

Key points
What was said, by whom, with the exact words. Timestamps jump to the moment.
- Shadé Zahrai
Zahrai argues that successful people do not eliminate self-doubt but strengthen themselves to move through it.
“those who are able to truly succeed, it's not that they eliminate the doubt, it's that they've found a way to strengthen who they are to move through it”
- Shadé Zahrai
Zahrai describes Kleck's scar experiment, in which participants whose scars were secretly removed still perceived judgment, as evidence of expectation bias.
“They created the reality they expected. And this is called expectation bias. We don't see the world as it is. We see the world as we expect it to be”
- Shadé Zahrai
Zahrai says senior and high-achieving people can have even more self-doubt because they feel they have more to lose.
“sometimes those who have achieved a lot, They have even more self-doubt because they feel like there's even more opportunity for them to fall”
- Shadé Zahrai
Zahrai contends self-doubt is misunderstood as one thing, leading people to seek a single solution that fails.
“we misunderstand self-doubt as being one blob of worry, insecurity, fear, and anxiety. And that means then if we think it's one thing, we think there's one solution”
- Shadé Zahrai
Zahrai recommends replacing over-apologizing with expressions of appreciation.
“So instead of, sorry, I'm talking too much, you would say, thank you so much for listening”
- Shadé Zahrai
Zahrai cites a study of Nobel Prize-winning scientists being far more likely to have hobbies, especially creative ones.
“those Nobel Prize-winning scientists were three times more likely than regular scientists to have a hobby and 22 times more likely to have a creative hobby”
- Shadé Zahrai
Zahrai says research shows positive affirmations backfire for people with low self-acceptance because they contradict self-image.
“if you struggle with self-acceptance and self-esteem, using positive affirmations backfires and makes you feel worse. Why? Because it contradicts how you see yourself”
- Shadé Zahrai
Zahrai argues feeling like an impostor is common and a sign of growth.
“some studies have found up to 82% of people have felt like an imposter at some point. And the beautiful thing about feeling like an imposter is it is a sign that you are growing”
- Shadé Zahrai
Zahrai claims chronic complaining strengthens neural pathways that make complaining a default.
“they are reliving the situation in vivid detail in their brain. which is creating deeper, more efficient neural pathways, which makes complaining your default”
- Shadé Zahrai
Zahrai recommends scheduling about 10 minutes of daily worry time in the late afternoon rather than trying to stop worrying.
“at the end of the day, you want to actually schedule in your calendar about 10 minutes of worry time. Not too close to bed because it might keep you up”
- Shadé Zahrai
Zahrai advises swapping 'should' for 'could' because 'should' triggers reactance and cuts off divergent thinking.
“research also shows that the language of should cuts off divergent thinking. We don't think as clearly. We don't think of solutions”
- Shadé Zahrai
Zahrai assesses Robbins's doubt profile as weak on acceptance and strong on autonomy.
“I think that your doubt profile from what you've shared with me, acceptance is your weak one. Autonomy is your absolute strength”
- Shadé Zahrai
Zahrai cites recent research suggesting the distance between chin and chest, rather than overall posture, drives feelings of confidence.
“It is the connection between chin and chest. The distance between your chin and chest is what determines how you feel”
- Shadé Zahrai
Zahrai says a deeper diaphragmatic voice leads others to perceive a speaker as more credible and confident.
“This deeper diaphragmatic voice, which comes with breath, it comes with gravitas, this leads to perceptions of greater credibility”
- Shadé Zahrai
Zahrai explains that early career experiences create schemas that people carry into new workplaces.
“there's something called career imprinting. where the first few experiences we have in our career end up shaping our sense of identity when it comes to our career”

Mel RobbinsRobbins attributes her strong sense of justice partly to her first job as a public defender.
“my first real big job out of college and law school was as a public defender. representing people in the justice system who could not afford a lawyer”
- Shadé Zahrai
Zahrai recommends lowering standards and aiming for good enough, citing Elizabeth Gilbert's approach to writing.
“sometimes we need to lower our standards sometimes. We need to lower our standards. Don't aim for perfection. Just aim for good enough for now”
