Core Idea

Brandolini's Law (the "bullshit asymmetry principle") states that the amount of energy needed to refute nonsense is an order of magnitude larger than the energy needed to produce it. A false claim takes seconds to make; debunking it requires evidence, context, and effort — and even then, the correction rarely travels as far as the original claim. For founders, this applies to misinformation about your company, bad-faith criticism, competitors' misleading claims, and internal rumours. The asymmetry means you can't win by refuting everything. You need a strategy for when to engage, when to ignore, and how to make truth travel faster than noise.

Section 2

How to See It

Public Narrative
You're seeing it when a false claim about your product or company spreads faster than your correction. By the time you've assembled the rebuttal, the original claim has moved on and new ones have appeared.
Internal Culture
You're seeing it when a rumour or misunderstanding spreads through the company in a day, but the clarification takes a week of all-hands, Slack threads, and one-on-ones to land. Misinformation is cheap; correction is expensive.
Section 3

How to Use It

Accept the asymmetry and plan around it. Don't try to refute every false claim — you'll exhaust yourself and amplify the noise. Instead: build a strong default narrative (proactive truth), pick battles where correction has high leverage (material claims, key audiences), and create systems that make truth travel fast (trusted channels, pre-built responses). On defence, make the cost of producing nonsense higher by demanding evidence and holding bad actors accountable.
Decision filter
"Is this false claim worth the energy to refute, or will engaging amplify it? Where is the highest-leverage point to set the record straight?"
As a founder
Build a proactive narrative so corrections are less often needed. When false claims arise, pick battles by materiality and audience reach. Don't play whack-a-mole with every piece of nonsense — that's the trap Brandolini's Law predicts. Invest in trusted channels that let truth travel fast.
Section 5

Founders & Leaders

Mark TwainAuthor; humorist; public intellectual
Twain observed that "a lie can travel half way around the world while the truth is putting on its shoes" — an early articulation of the asymmetry Brandolini formalised. As a public figure constantly misquoted and misattributed, Twain learned that correcting every falsehood was futile. Founders face the same: competitors mislead, critics distort, rumours spread. The Twain lesson is strategic restraint — build a reputation strong enough that false claims bounce off, pick your battles on substance not volume, and invest your energy in building rather than refuting.
Section 7

Connected Models

Reinforces
Asymmetric Warfare
Brandolini's Law is informational asymmetric warfare — the attacker (misinformation) has lower cost than the defender (truth). The same strategic principles apply: don't fight on the attacker's terms. Change the battlefield.
Reinforces
Signal vs Noise
Nonsense increases noise; refutation is an attempt to restore signal. Brandolini's Law warns that noise production is cheap and signal restoration is expensive — invest in signal amplification, not just noise suppression.
Tension
Burden of Proof
Burden of proof says the claimant must prove the claim. In practice, Brandolini's Law means the burden often falls on the refuter — the false claim circulates while the debunker does the work. The tension: norms say prove it; reality says disprove it.
Section 8

One Key Quote

"The amount of energy needed to refute bullshit is an order of magnitude bigger than to produce it."

Summary & Further Reading

Brandolini's Law: misinformation is cheap to produce and expensive to refute. Don't try to debunk everything. Build proactive narrative, pick high-leverage battles, and invest in channels that make truth travel faster than noise.
