Memory and Information Processing Biases

Restraint bias

Restraint bias is a cognitive bias wherein individuals overestimate their ability to control impulses or resist temptations. This often results in exposing oneself to situations with higher risk of succumbing to temptation, as the perceived self-control is mistakenly assumed to be sufficient to handle it.

Mechanism

How it works

Restraint bias functions by skewing an individual's perception of their own self-control. People may believe they can handle temptations better than they actually can, leading to overconfidence. This misjudgment can arise from underestimating the power of immediate temptations or from a failure to accurately recall past instances of lost control.

Examples

Where it shows up

A person with restraint bias might believe they can have potato chips in the house and eat them only occasionally, despite past behavior showing they binge on them regularly.
A student might feel confident that they can resist the distraction of social media during study sessions, leading them to keep their phone nearby, but ends up spending hours scrolling instead of studying.

Consequences

What it can distort

The overconfidence stemming from restraint bias can lead to overexposure to temptations, resulting in repeated failures to achieve goals, such as dieting, saving money, or maintaining productivity. This can cause frustration, decreased self-esteem, and potential negative impacts on personal and professional relationships.

Countermeasures

How to work around it

To counteract restraint bias, individuals can practice self-awareness and mindfulness to better recognize their limits. Setting stricter boundaries or using external tools such as apps to block distractions can help. Seeking feedback from others and reflecting on past instances where control was lost can also provide more realistic insights into one's capabilities.

Caveats

Critiques and limits

Some critiques of the concept of restraint bias focus on the influence of external factors such as stress or peer pressure that might override perceived self-control, suggesting that the bias isn’t solely a misjudgment of personal ability. Additionally, there are arguments regarding the lack of universal applicability of the bias across different cultural contexts or personality types.

Margin of Error: When a Mobile Trading App Meets Overconfidence

A real-world example of Restraint bias in action

Context

A 34-year-old software engineer with a moderate savings account signs up for a popular mobile microtrading app that markets itself on ease and real-time alerts. He has limited prior active trading experience and a long-term retirement plan but believes he has strong impulse control and can resist speculative trades.

Situation

The app sends curated 'top mover' push notifications and offers one-tap leveraged trades. Convinced he can ‘just look’ and resist acting on hype, he leaves notifications enabled and does not set any trading limits or cooling-off mechanisms.

The bias in action

Believing he can control impulses, he repeatedly exposes himself to high-frequency temptation (push alerts, trending tickers). Each alert became an environment cue, and he overrode initial doubts because he assumed he'd refuse impulsive trades. Over a short period he started placing small leveraged trades 'just to check' and then escalated position sizes after a few small wins. His confidence in self-control prevented him from creating safeguards (cool-off periods, daily loss limits) that would have reduced exposure.

Outcome

Within three months his trading frequency rose sharply and small losses accumulated into a significant drawdown. Short-term gains early on reinforced his belief in control, but subsequent market swings amplified losses and fees. He experienced financial losses and increased anxiety, and he delayed planned retirement contributions to cover margin calls.
