To join — always free
Stay current in influence science — and never practice it alone.
The Community keeps the research at your fingertips and the right people in your corner. Here is what arrives once you join.
Monthly Influence Science Brief
A curated research summary, real-world case study, and one practical application of the 7 Principles of Persuasion — delivered to your inbox the first week of every month.
A Network of Practitioners
Trade tactics with marketers, leaders, negotiators, and educators who apply influence ethically every day. Share a win, pressure-test an idea, find a peer who gets it.
Members-Only Sessions
Sit in on quarterly live Q&As and behind-the-scenes conversations with Dr. Cialdini and Institute faculty — recordings reserved for members, never published publicly.
Early & Priority Access
Hear about new programs and certification cohorts before the public announcement, so you can plan around the dates that suit you and register early.

The science only matters when people put it to work together. That is what this community is for: read the brief, join the conversations, and bring what you learn back to your own work.

See your influence profile before you read a single brief.
The Influence Assessment shows which of the 7 Principles you already lean on and where your biggest gains are — so every brief that follows lands on a profile you already know.
