People Place Larger Bets When Risky Choices Provide a Postbet Option to Cash Out.

Area of Science:

• Behavioral Economics
• Decision Making
• Gambling Psychology

Background:

• Decision-makers often face delays between making a choice and learning its outcome.
• Modern sports-betting platforms offer a 'cash-out' feature, allowing early withdrawal of discounted payouts during the delay period.

Purpose of the Study:

• To investigate how the availability of a post-choice cash-out option influences decision-making in gambling contexts.
• To understand the behavioral impact of cash-out features on bet amounts and participant choices.

Main Methods:

• A novel gambling task was designed, integrating a cash-out option during the bet-outcome delay.
• Two experiments were conducted with 240 adult participants recruited via Prolific.
• Data collected included bet amounts, cash-out decisions under varying odds, and individual differences in cash-out propensity.

Main Results:

• Cash-out availability led to an increase in participants' bet amounts, up to 35%.
• Participants showed differential cash-out behavior: more likely to cash out when odds deteriorated, less so when odds improved.
• The increase in bet amounts due to cash-out availability was positively correlated with cash-out propensity, specifically for bets with deteriorating odds.

Conclusions:

• The availability of a cash-out option can encourage larger initial bets in gambling scenarios.
• This effect appears driven by the perceived ability to mitigate losses, particularly when facing deteriorating odds.
• Individual differences in risk aversion and cash-out strategy moderate the impact of this feature on betting behavior.
