Endorsing a product, writing a review, or speaking for another person ties your reputation to theirs. The Manifesto calls the endorsement of a person edification, an exchange of influence that creates credibility by association, the opposite of guilt by association.
If an endorsement goes wrong, you can withdraw it, but you must explain why. A bare withdrawal looks like you have something to hide.
Your followers have expectations and endorsements are extensions of your good faith and your personal influence.

How to Endorse Well
Do Your Due DiligenceFor a product, look at who built it and who promotes it. For a person, look at their narrative, your experience with them, and why they are asking.
Speak From ExperienceEdify someone with what you have actually seen them do.
Withdraw With ReasonsIf you must withdraw, explain why, with class and emotional awareness.
Give Without Being AskedAn unprompted endorsement carries the most good faith and the least risk.
Putting It to Work
The moves ISIA, the engine behind the Brand Audit, draws from this part of the doctrine. Each one is something you can do this month, and the reason it matters.
Vet Before You EndorseBefore any endorsement: research the makers, the other promoters, and the history, and speak with the team. For a person: their narrative, values, and your own experience with them.Why: Your name is the collateral on every endorsement.Reputational Health & Risks
Endorse Others Without Being AskedEach month, publicly recommend one person whose work you genuinely vouch for. Speak from real experience.Why: Edification compounds. Becoming a public figure requires enough people edifying you unprompted, and it starts with doing it for others.Credibility
Keep Other Income So You Are Never Chasing ChecksMake sure no single sponsorship or deal is money you cannot walk away from. It keeps your endorsements credible.Why: An audience can tell when someone is chasing checks. Other income protects your judgment.Reputational Health & Risks
Where It Comes From

Personal Branding: A Manifesto on Fame and Influence, Second Edition (Mashman Publishing, 2025)
The endorsement of an individual: someone speaking supportively about another person's accomplishments and character. It is how influence is exchanged.
Can I withdraw an endorsement?
Yes, but you may lose credibility, and you need to explain why. A withdrawal without reasons suggests you have something to hide.
In Isaac's Words
From the Interviews, on Giving Endorsements.
Advice Isaac Mashman has given on his own shows and in interviews on this subject, from the same library MCG consultants work from. Each one keeps the words he said it in, and links to the transcript where there is one.
Credibility
Gather Letters and Testimonials From People of Standing
When a respected person offers to vouch for you, accept and keep it on record. Ask clients for video testimonials for the same reason.
