"The amount of energy needed to refute bullshit is an order of magnitude bigger than that needed to produce it."
— Alberto Brandolini, Italian programmer, January 11, 2013
In 2013, Italian software engineer Alberto Brandolini was watching a political debate featuring former Prime Minister Silvio Berlusconi. He observed one politician spewing a firehose of misleading claims while the other struggled to correct even a fraction of them.
After reading Daniel Kahneman's Thinking, Fast and Slow, Brandolini crystallized this observation into what became known as Brandolini's Law — the fundamental asymmetry between creating false claims and debunking them.

Why Debunking Is So Hard
Creating Bullshit
✓ Uses intuition, not analysis
✓ No evidence required
✓ Infinite ways to be wrong
✓ Vague claims resist scrutiny
✓ Simple narratives are sticky
Refuting Bullshit
✗ Requires analytical reasoning
✗ Must gather evidence
✗ Must address every variation
✗ Must clarify vague claims
✗ Complex truths are boring

Social media amplifies the asymmetry: misinformation spreads 6× faster than corrections on Twitter.
Even when bullshit is successfully refuted, people often continue believing it due to confirmation bias, the reach problem (corrections never reach everyone), and the psychological persistence of simple, emotionally resonant narratives.
The only winning move? Focus on prevention over correction—teaching critical thinking before exposure to misinformation.
