The 'projection bias' of grocery shopping on an empty stomach
Your brain is a terrible time traveler. When you hit the grocery store while starving, you fall victim to "projection bias." You’re hallucinating that your current hunger is a permanent state, not a temporary signal.
This is a failure of affective forecasting. You overvalue the future utility of snacks because your blood sugar is in the basement. You’re shopping for a version of yourself that is perpetually famished.
Once full, that mountain of food becomes a costly monument to your irrationality. Your wallet pays for your stomach's inability to see past the next twenty minutes.
Precisely. This is the "hot-to-cold empathy gap." When you’re in a "hot" state—furious, heartbroken, or caffeinated—you lose the ability to imagine what "cool" headedness feels like.
It’s why you buy a treadmill during a midnight burst of motivation, only to use it as a laundry rack. You’re falling for hyperbolic discounting, valuing immediate "highs" over long-term reality.
Your brain is a terrible narrator who thinks the current chapter is the entire book. You aren't making choices for "you"; you're making them for a temporary stranger.
You need a "commitment device"—basically a trap you set for your own future stupidity. It’s the psychological equivalent of freezing your credit card in a block of ice to stop 2 a.m. impulse buys.
You’re acknowledging that "Future You" is an unreliable narrator. By creating friction now—like deleting delivery apps or automating savings—you outsmart the stranger before they even arrive.
It’s not about willpower; it’s about making the "wrong" choice so annoying that even your most impulsive self is too lazy to follow through.
That’s why it’s called a "Ulysses contract." Odysseus didn't just "promise" not to jump; he had his sailors tie him to the mast. He engineered a situation where his future whims were physically irrelevant.
The trick is making the "undoing" take longer than the impulse. If you have to wait for ice to melt to get your credit card, your rational brain usually has time to stage a coup.
This is "pre-commitment." You're effectively gagging your future self so they can't talk you into another bad decision.
You don’t need a crew of burly Greeks; you need "accountability sinks." These are external systems or people that make the social cost of failing higher than the temporary pleasure of the impulse.
Think of it as "social collateral." If you tell your most judgmental friend you’re quitting caffeine, the fear of their smug "I told you so" becomes the rope holding you to the mast.
You’re essentially weaponizing your own ego. You’d rather suffer through a craving than pay the "reputation tax" of being a total flake.
