Mastermind group: how it works, and how to choose one

Varch editorial · Reviewed October 16, 2026 · 7-minute read · Sources at the end

A mastermind group is a small circle of peers who meet to sharpen each other’s decisions and keep each other moving. The idea is almost a century old, and the evidence behind its core mechanics, peers and progress tracking, is solid. Here is how it works and the questions to ask before you join one.

Where the idea came from

Napoleon Hill popularized the term in his 1937 book Think and Grow Rich, describing the “master mind” as two or more people coordinating knowledge and effort in harmony toward a definite purpose. Hill’s book is motivational writing, not research. The mechanics that make a group useful, though, have been studied.

What the research supports

People who track progress reach goals more often, especially when they report it to others: that was the finding across 138 studies with 19,951 participants (Harkin and colleagues, 2016). Social support helps people keep going: in one trial, people who joined with friends and had support were far more likely to finish and maintain results than people who joined alone (Wing and Jeffery, 1999).

What a good group does

  • Shares a model. Members measure progress the same way, so feedback is specific.
  • Brings real decisions. Not updates for show; choices that need other angles.
  • Keeps a rhythm. Regular meetings or check-ins, kept.
  • Protects the room. No selling to each other.

Questions to ask before you join

  1. What exactly is included, and for how long?
  2. Who else is in it, and how are members chosen?
  3. Is there a shared framework, or does each person bring their own?
  4. Is selling to members allowed?
  5. What are the terms if it is not for you?

Group readiness check

1 = not true · 5 = very true

1I have a decision I would like other angles on.
2I am willing to report my numbers to peers.
3I can commit to a regular rhythm for a year.
4I want peers more than a coach.
5I would rather share a framework than start from scratch.

Questions about mastermind groups

How many people are in a mastermind group?

Classic masterminds are small, often under ten. Larger communities work differently, with more members and less structure per person.

Is a mastermind group the same as coaching?

No. A mastermind is peers helping peers; coaching is a professional guiding a client.

What should a mastermind group cost?

Prices vary widely. Judge on what is included, how long it runs, who is in it and the terms.
