The Hidden Bias of Betting Markets: How Human Psychology Forces a Betting Broker to Correct Predictive Errors

Over the years in betting the data also show one pattern repeating over and over again and the odds you see are not just math, they are odds of what should happen vs odds of what a better thinks will happen.

In this article, we cover: Why betting long-shot will drain your bankroll significantly quicker than betting on the favorites. Which 3 mental costs a bettor money. How a broker changing the odds in less than 1 second.

The Favorite Longshot Problem

Longshots over time lose money faster than betting on the favourites, and this are something that I’ve saw long enough to experience first-hand. A longshot is a team that is outrighly favoured to win with 100 to 1 odds in their favour. A favourite is a team with a high chance of winning that is placed with low odds, once again a 2 to 1.

A team that is placed way over 100 to 1 is because the betting odds suggest that their chance of winning is in fact a staggering 300 to 1. Then, that 2 to 1 favourite should also win and most likely to win but should come in low it to just 1.5 to 1.

The Results show the results clearly. Betting on the favourites you will lose over time 5% of your stake and backing longshots you will lose 50% of your stake. This means that if you are betting longshot odds your problems are going to worsen exponentially, and this pricing problem is the problem that most betting broker has to watch and fix daily.

Three Mental Tricks That Cost Bettors Money

I’ve seen these mistakes wreck strategies hundreds of times. Here are the big three:

Biases such as overconfidence do the most damage. Overconfidence leads recreational bettors to greatly overestimate their predictive abilities. Recreational bettors likely consider themselves to be better, on average, than their true forecasting ability. They remember the winning bets but are less likely to recall their losing bets. This leads to over-betting as well as over-frequent betting.

With confirmation bias, some bettors see nothing but the outcome they want. Let’s say they want a Manchester United to win:

● They will remember only the five game winning streak at home.

● They will ignore the injured players on their team.

● They will overlook the opposing team who has a strong away record.

I catch myself doing this too – it leads to one sided betting, a practice that is used in surge pricing by betting pros.

The gambler’s fallacy leads to the creation of fictitious dependencies, such as patterns that do not exist. After a team has lost five games in a row, they will accumulate bets on that team because they think they are “due” for a win. They will be surprised to learn that in betting, every game is a separate event.

How Betting Brokers Real-Time Adjust Mistakes

Professional bookmakers can track betting patterns with extreme finesse. When large bets are placed on one side, prediction sites like FocusPredict, can identify this almost immediately. They subsequently shorten the odds on this pick and lengthen them on the other side. This is done to mitigate the potential loss if the majority happens to be correct.

Economist Steven Levitt studied this and concluded that bookmakers understand reading probabilities better than the average bettor. Research done by Snowberg and Wolfers claims the longshot bias which costs bettors large amounts is driven by false probability perception. They are aware of how casual bettors tend to side with popular teams, and when bets are placed on the favorites, they adjust the lines to make this more unfavorable. The market has absorbed the public’s mistakes by the time sharp bettors enter the market with large bets placed.

Final Take On Betting Psychology

These biases are real and understanding them won’t make them disappear. Insight informs you that your brain is tricking you into false patterns and longshot bias to overvalue. Bookmakers understand this as well. This is why they are continually adjusting lines to account for profit due to these patterns.
