Asked how to avoid being persuaded, Adams starts by conceding the technique's limits: he feels himself being persuaded all the time despite having every tool, and claims only 'a little protection'. The defense has four parts. First, learn persuasion itself — knowing how irrational people are helps. Second, audit your agreement rate with your own team: if you never seriously disagree, you have a problem and you're probably not a serious player. Third, run the source-swap test — would I feel the same if a Democrat said this instead of a Republican? Fourth, expand your information silos deliberately, because seeing only one tunnel makes understanding the full situation impossible. He adds a blunt warning that many headlines are literally fake, typically a long quote cut to show only the first part, reversing its meaning.
Origin
Adams developed this as the defensive counterpart to Win Bigly's offensive playbook, and previewed it as the subject of his next book, Loser Think, published November 5th 2019 — which he described as teaching readers more about how to break out of their bubble.
Core principles
- 01Even experts get persuaded — Adams says he feels it happening constantly.
- 02Knowing how irrational people are is itself the first layer of protection.
- 03If you never disagree with your team, you're not a serious thinker.
- 04The source-swap test isolates whether you're reacting to content or to identity.
- 05Seeing only one silo makes full understanding impossible by construction.
How to run it
- 1
Learn persuasion itself
Study as much about persuasion as possible. Adams' claim is that knowing how irrational people are is the foundational protection — you can't defend against a technique you can't recognise.
Pro tip Adams offers Win Bigly as an introduction that references further sources.
Watch out Even full knowledge is only partial protection. Adams says he gets persuaded anyway.
- 2
Audit your team agreement rate
Look at how often you agree with your own team and whether you ever seriously disagree. If you never do, you have a problem — Adams says you're probably not a serious player.
Pro tip Occasional genuine disagreement is the evidence you're not fully inside the bubble.
- 3
Run the source-swap test
Ask: if this were some other person in the situation, would I have the same feeling? Would I react identically if a Democrat said exactly what a Republican just said?
Pro tip Adams calls this 'a good test' — it isolates the content from the identity of the speaker.
- 4
Expand your silos deliberately
Expose yourself to as many different opinions as possible. Adams uses Fox and CNN as proxies: see only one tunnel and you couldn't possibly understand the full situation.
Watch out This is structural, not attitudinal. A single silo makes understanding impossible regardless of how open-minded you feel.
- 5
Assume headlines are often fake
Adams means this literally: a common pattern is a long quote cut to show only the first part, which reverses its meaning. Go to the full quote before reacting.
In the wild
Adams claims that on the day of the interview, almost all the headlines in the news were literally fake — built by taking a long quote and showing only the first part, which reverses the meaning of the whole statement.
→ His prescription: treat headline outrage as unverified until you've read the full quote, and expect the pattern over and over again.
Adams' diagnostic is to look at how often you agree with your own team and whether you ever seriously disagree. Never disagreeing is the tell.
→ If you sometimes disagree, that gives you some hope you might be breaking out of your bubble; if never, you're probably not a serious player.
Common mistakes
Believing expertise makes you immune
Adams has every tool available and says he still feels himself being persuaded all the time, claiming only a little protection. Anyone who thinks they're immune has already lost the audit.
Consuming one silo and calling it informed
Seeing only the tunnel one side presents makes understanding the full situation impossible by construction — no amount of attention within the silo fixes it.
Reacting to headlines
Adams says the truncated-quote pattern is pervasive and meaning-reversing. Reacting before reading the full quote is participating in the persuasion, not resisting it.
Is it for you?
Best for
Anyone who wants their positions to be their own rather than their team's.
Not ideal for
People seeking a guaranteed defense — Adams explicitly says it only offers 'a little protection'.
From the transcript
“It's very hard, because even people who are experts at this can be persuaded. I feel myself being persuaded all the time, and in theory…”
“Look for how often you agree with your team, and whether or not you ever disagree seriously. Cuz if you never disagree with your team,…”
“If it were a Democrat who said it, would I feel the same as if a Republican said exactly the same thing. That's a good…”
“If you don't see both sides, and you only see the little tunnel that one side presents, you couldn't possibly understand the full situation.”
