G.I. Joe Fallacy – when you think knowing a bias makes you immune to it
Do you think that just knowing about cognitive biases makes you immune to them? That’s G.I. Joe Fallacy – the belief that awareness of a bias is enough to eliminate its effects. Unfortunately, self-control doesn’t work that way.
Where it can show up
- Financial decisions – even knowing about the ‘sunk cost fallacy,’ you still cling to bad investments.
- Productivity – you read books on time management but still procrastinate.
- Stereotypes – you understand that biases are bad, yet you still catch yourself making stereotypical judgments.
A practical countermeasure
- Practice, don’t just learn – recognizing a bias doesn’t mean you’ll stop falling for it.
- Build systems, don’t rely on willpower – if you know you’re prone to an error, set up safeguards against it.
- Stay humble – even the smartest people fall into cognitive traps.
