Decision Swear Jar
Catch your own irrational thinking patterns with trigger words
Just as a swear jar creates mindfulness around profanity by imposing a small penalty each time, a Decision Swear Jar creates mindfulness around irrational thinking patterns by identifying specific words, phrases, and thought patterns that signal cognitive bias. When you catch yourself using these trigger phrases -- such as 'I knew it all along,' 'they always get lucky,' or 'worst day ever' -- the recognition itself creates a decision interrupt that can prevent you from acting on the underlying bias.
The power of this framework is in its simplicity and accessibility. You do not need to understand the neuroscience of cognitive bias to benefit. You simply need a list of phrases that, when you catch yourself saying or thinking them, should give you pause. Each phrase maps to a specific bias: 'I knew it' signals hindsight bias; 'worst day ever' signals temporal magnification; 'they totally deserved that' signals the self-serving bias applied to others.
The Decision Swear Jar is an especially effective Ulysses Contract because the trigger words are so common in everyday language that you will encounter them frequently, creating many small opportunities to practice catching yourself. Over time, this builds the habit of metacognitive awareness -- thinking about your thinking -- which is the foundation of all de-biasing work.
- Specific words and phrases are reliable signals of specific cognitive biases.
- Catching yourself using trigger phrases creates a natural decision interrupt.
- Small, frequent practice with low-stakes situations builds the habit for high-stakes ones.
- The goal is not to eliminate the phrases but to use them as triggers for reflection.
- A group commitment to the swear jar amplifies accountability and speeds habit change.
- Create your trigger phrase listIdentify words and phrases that signal irrational thinking. Common examples include: 'I knew it' (hindsight bias), 'I'm 100% sure' (illusion of certainty), 'worst day ever' (temporal magnification), 'they got lucky' (self-serving bias), 'everyone agrees' (echo chamber), and 'that's wrong' (false certainty).Pro tipStart with five to ten phrases and expand as you notice more. Ask your truthseeking pod to help identify your personal favorites.
- Monitor your language for one weekCarry the list with you (physical or digital) and mark each time you catch yourself saying or thinking one of the trigger phrases. Do not try to change the behavior yet -- just observe and count. This builds awareness of how frequently these patterns occur.Pro tipYou will be surprised at how often these phrases appear. That surprise itself is a useful data point about how deeply embedded the biases are.
- Use each trigger as a decision interruptOnce you have awareness of your patterns, begin using each trigger phrase as a prompt to pause and reflect. When you catch yourself saying 'I knew it,' stop and ask: 'Did I really know it, or am I retroactively fitting the outcome to my beliefs?' When you say 'worst day ever,' ask: 'Will this matter in ten months?'Pro tipPair each trigger phrase with a specific reflection question to make the interrupt automatic.
- Implement the jar with your groupIf you are part of a truthseeking pod or a team, make the swear jar collective. When anyone uses a trigger phrase, it is flagged -- not punitively, but as an opportunity for reflection. The group accountability dramatically accelerates the habit change.Pro tipMake it fun and low-stakes. The point is awareness, not punishment.WarningIf the jar feels punitive rather than playful, people will stop being honest about their thinking.
A CEO catches herself saying 'I'm absolutely sure this market strategy will work' and pauses. The trigger phrase 'absolutely sure' prompts her to ask: What am I really sure about? What is my confidence level on a 0-10 scale? What are the alternative scenarios I haven't considered?
A poker player catches himself saying 'I can't believe how unlucky I got' after losing a series of hands. The trigger prompts him to ask: Was it really all luck? Were there decision points where I could have played differently? The reflection reveals two hands where his strategy was suboptimal.
Duke developed this concept as a practical, accessible implementation of the broader truthseeking principles. She observed that certain phrases reliably predicted irrational decision-making in poker players and business executives alike. By cataloging these phrases and treating them as signals rather than just language, she created a low-friction tool that anyone could use immediately to start catching their own bias in action.
