Challenge Network Method
Assemble a team of trusted critics who push you through honest feedback
The Challenge Network Method is Adam Grant's formalized approach to building a group of trusted people whose explicit role is to disagree with you, poke holes in your thinking, and push you to produce your best work. Inspired by the culture of radical transparency at Bridgewater Associates, Grant distinguishes between a support network (cheerleaders who build your confidence) and a challenge network (critics who improve your quality). The framework recognizes that most people surround themselves with supporters but systematically avoid critics, which means their ideas, work, and decisions never receive the stress-testing needed for excellence. A great challenge network member pushes you because they believe in you — it is tough love, not hostility. Grant implements this through student groups who compete to give the most devastating criticism of his book drafts, colleagues who are explicitly told that their role is to challenge his thinking, and a practice of soliciting criticism after every public appearance. The method also includes specific techniques for making critics feel safe enough to be honest, such as having a senior member model extreme criticism at the first meeting and responding with visible curiosity rather than defensiveness. The framework fundamentally redefines the value of criticism from something to be avoided to something to be actively sought.
- A challenge network improves quality; a support network improves confidence — you need both
- The best challenge network members push you because they believe in you, not to tear you down
- Making criticism explicit and structural removes the social awkwardness that prevents honest feedback
- Model the reception of extreme criticism with curiosity and openness to set the norm for others
- Soliciting criticism is a sign of strength, not weakness — the more you accomplish, the easier it becomes
- Identify Your Potential ChallengersLook through your professional and personal network for people who have demonstrated intellectual honesty, domain expertise, and a willingness to disagree with you in the past. These are people who care enough about you or your work to tell you uncomfortable truths. They may be colleagues, mentors, students, or peers. The key criterion is not whether they are nice but whether they are honest and have good judgment in areas relevant to your work.Pro tipThink about who has given you the most painful but most useful feedback in the past. Those people are your natural challenge network candidates.WarningAvoid people who are critical for the sake of being critical without constructive intent. Pure negativity is not the same as productive challenge.
- Make the Role ExplicitReach out to each person and explicitly tell them you consider them part of your challenge network. Grant did this by saying: I want you to know that I consider you a founding member of my challenge network. I know I am not always as receptive to your criticism as I would like to be and sometimes that is frustrating for you, but I keep coming to you because I know I need it. Making the role explicit gives them permission to be more honest and removes the social friction that normally suppresses useful criticism.Pro tipAcknowledge upfront that you may sometimes react defensively, and ask them to push through that reaction because you value the feedback even when you do not like it.
- Structure Regular Challenge SessionsFor major projects, schedule regular meetings with your challenge network — Grant uses biweekly sessions during book writing or podcast production. At the first meeting, have a senior or experienced member come in with the toughest possible criticism to model the expected level of honesty. Respond with visible curiosity and openness to set the norm. Over time, this structure produces increasingly honest and useful feedback as people learn that challenge is genuinely welcomed and rewarded.Pro tipFrame the task explicitly: Your job is to violently disagree with every word I write. Make it a competition to see who can give the most devastating criticism.
- Solicit Micro-Challenges SpontaneouslyBeyond structured sessions, build the habit of soliciting challenge after every presentation, meeting, or publication. After getting off stage, ask: What is the one thing I can do better? If people deflect with nothing or that was great, push them by saying: I thought you had higher standards than that. You could not find a single thing I could improve on? If they still will not engage, criticize yourself out loud and ask if they agree with any of your self-assessments. This almost always unlocks honest feedback.Pro tipThe question 'What is the one thing I can do better?' is more effective than 'How did I do?' because it assumes there is something to improve and gives permission to name it.
As a first-time graduate student teacher, Grant received harsh feedback from students about his nervous teaching style and poor time management. Rather than hiding the feedback, he typed it up verbatim and emailed it to the entire class, then devoted a whole class session to discussing improvements. His advisor warned this would cause a mutiny, but instead it transformed the students into engaged coaches who helped him improve dramatically.
When writing books, Grant sends each chapter draft first to a group of students whose explicit job is to compete to give the most devastating criticism. One student memorably told him: At no point at any time during reading this chapter did I feel like I could say the words page turner. This level of honesty produced books that became number one New York Times bestsellers.
Grant began building his challenge network accidentally when, as a terrified graduate student teaching his first class, he shared all student feedback verbatim with the entire class and devoted a session to discussing improvements. This radical openness transformed students into coaches. The concept crystallized when Grant visited Bridgewater Associates for his WorkLife podcast and recognized that Ray Dalio had built an entire company around the challenge network concept. Grant then formalized his own version, reaching out to key critics in his life to explicitly tell them he considered them founding members of his challenge network and valued their criticism even when it was uncomfortable.
