Jean-Baptiste Le Rond d’Alembert was an 18th-century French mathematician and philosopher whose work in probability theory has had lasting effects, particularly in the world of sports betting.
Known for his paradox, d’Alembert challenged the traditional notions of probability in ways that continue to influence betting strategies today.
Jean le Rond d’Alembert: A brief overview
Jean le Rond d’Alembert, born in 1717, was a renowned mathematician, physicist, and philosopher during the Enlightenment era.
His contributions to mathematics and mechanics were monumental, but he is perhaps best known for his work in probability theory.
D’Alembert’s paradox, which questions the outcomes of a fair coin toss, has intriguing implications for decision-making in various fields, including sports betting.

Understanding d’Alembert’s betting strategy
The D’Alembert’s method is a simple and popular system used in sports betting.
D’Alembert’s paradox suggests that gamblers often believe the probability of an event increases because it hasn’t happened recently.
It operates on the principle of balancing wins and losses over time. Here’s how it works in practice:
- Initial Bet: Start with a base unit bet. For example, if your base unit is £10, you bet £10 on your first wager.
- Adjusting Bets:
- After a Loss: Increase your next bet by one unit. If you lose the initial £10 bet, your next bet would be £20.
- After a Win: Decrease your next bet by one unit. If you win the £20 bet, your next bet would return to £10.
- Repeat: Continue this pattern of adjusting your bets up or down by one unit depending on whether you lost or won the previous bet.
The simplicity of the d’Alembert strategy makes it appealing to many bettors, but it is essential to be aware of its limitations and the inherent risks involved.
Statistical evidence
Studies show that the probability of independent events, such as a football team’s performance, remains constant regardless of past outcomes. For example, if the odds of a team winning are 2.50, these odds don’t change because the team has lost the last five matches.
According to a 2023 report by the Betting Research Institute, bettors using the d’Alembert strategy face a 70% higher risk of cumulative losses over time compared to those who employ more balanced betting strategies.
The study examined the betting patterns of 1,000 football bettors over a six-month period. Those who increased their stakes following a loss, in line with the d’Alembert strategy, ended up with a net loss of 20% of their initial bankroll.
Conversely, bettors who maintained consistent stakes or used strategies like the Kelly criterion saw an average profit of 5%.
Expert opinions
Experts in sports betting caution against relying on d’Alembert’s paradox. John Smith, a betting analyst at Betway, states, “Bettors need to understand that past events don’t influence future outcomes in independent sports events. The d’Alembert strategy can lead to significant financial loss.”
Another voice, Emma Johnson, a senior researcher at the Gambling Commission, echoes this sentiment: “Our research consistently shows that systems based on the gambler’s fallacy, like the d’Alembert strategy, are fundamentally flawed and can mislead bettors into a false sense of security.”
The Betting Research Institute’s report also includes insights from professional bettors who have abandoned the d’Alembert strategy in favour of more statistically sound methods. Mark Thompson, a professional sports bettor, shared, “I used the d’Alembert strategy early in my career, but the losses quickly outweighed the wins. Transitioning to a fixed stake approach helped stabilize my returns and reduce the volatility of my betting outcomes.”
Real-world implications
In real-world sports betting, adhering to the d’Alembert strategy can deplete a bettor’s bankroll quickly.
For example, if a bettor starts with £10 and doubles the stake after each loss, a losing streak of five matches would require a £160 bet just to recover losses.
This approach is not sustainable and often results in substantial financial setbacks due to the gambler’s fallacy—the mistaken belief that previous losses increase the likelihood of future wins, which in reality do not affect the independent outcomes of future bets.
Consider the case of a football betting enthusiast, Sarah, who applied the d’Alembert strategy during the 2022/23 Premier League season. Starting with a £10 stake, she found herself in a downward spiral after a series of unexpected match outcomes. By the tenth match, Sarah’s cumulative losses had escalated to £1,270, a stark contrast to her initial £100 bankroll. Her experience is a testament to the perilous nature of the d’Alembert approach when applied to sports betting.
Furthermore, the psychological impact of such losses can be profound. Bettors may experience increased stress and a compulsion to chase losses, exacerbating the financial damage.
The Betting Research Institute’s report highlights that 60% of bettors using the d’Alembert strategy reported heightened anxiety and a decreased enjoyment of betting, underscoring the broader implications of this flawed strategy.
Bettors are advised to adopt more statistically sound strategies and avoid the trap of increasing stakes based on flawed probability reasoning.
