Restraint Bias — When Logic Wears a Disguise
Restraint Bias is the tendency to overestimate one's ability to control impulsive behavior. People who believe they have strong self-control are paradoxically more likely to place themselves in situations of temptation, which in turn increases the probability that they will succumb to the very impulses they thought they could resist. Identified by Nordgren, van Harreveld, and van der Pligt (2009), the bias explains why self-perceived moderates often relapse, while those with lower self-assessments of control tend to avoid triggering situations altogether.

How It Works
People in a 'cold' state (not currently tempted) systematically underestimate the power of 'hot' states (actively experiencing desire or craving). The visceral pull of temptation is invisible from a distance, leading to overconfidence in one's future self-regulation.
A Classic Example
A recovering alcoholic, confident in their sobriety, volunteers to bartend at a friend's party—reasoning that they can handle it. As the evening progresses and social pressure mounts, they take a drink.
More Examples
A dieter buys a large bag of cookies for 'emergencies only,' certain they won't touch them—and finishes the bag within two days.
A procrastinator signs up for a tight project deadline because they're confident they'll buckle down when the time comes, only to find themselves unable to resist distractions when the deadline approaches.
Where You See This in the Wild
Dieters who keep junk food in the house 'just for guests' tend to consume it themselves. Gamblers who believe they can set hard limits often extend their bets beyond them once in the casino.
How to Spot and Counter It
Adopt situation-level prevention rather than relying on willpower: avoid environments where temptation is present rather than planning to resist it in the moment. Recall specific past failures of self-control when assessing future risk.
The Takeaway
The Restraint Bias is one of those reasoning errors that sounds perfectly logical at first glance. That's what makes it dangerous — it wears the costume of valid reasoning while smuggling in a broken conclusion. The best defense? Slow down and ask: does this conclusion actually follow from these premises, or am I just connecting dots that happen to be near each other?
Next time someone presents you with an argument that "just makes sense," check the structure. The feeling of logic is not the same as logic itself.
