In very basic terms, a cognitive bias is an observed departure from rational judgment. It’s a habit which the brain develops which leads us to judge things in an inefficient manner. When gambling, predicting results effectively requires the most rational judgment, so cognitive biases place us behind the eight-ball before we’ve even looked at our first formguide!
The good news however is that doctors, scientists and various other people in white coats have been studying this stuff for centuries, and have been able to at least identify and label different types of cognitive biases. There’s a very long list of them. So as natural as cognitive biases may be, at least we know they exist. Which means we can take steps to combat them.
Outcome bias refers to a tendency by humans to judge an entire event, and the decision they took in the lead-up to it, entirely on the outcome. If you consider that cognitive biases are generally just shortcuts that our brains take when processing events, this becomes understandable.
If a football team lost, they performed poorly. But if they won, then their performance was satisfactory.
The problem is that outcome bias completely ignores why something happened. And more importantly when it comes to gambling, it can place an enormous weight on factors that the gambler himself (or herself) cannot control.
Let’s say you’re trying to make money betting on horses (that’s a fair assumption!). The first thing to recognise is that, dodgy jockeys aside, the punter has absolutely no control over how a particular horse will run. None. You have zero impact on the outcome of a race.
That sounds absurdly obvious. So how can you judge a punter’s performance purely on the outcome of a race? That’s outcome bias.
It entirely ignores the why.
Why did the race pan out the way it did? Did one or more horses perform in an entirely unpredictable manner, be that positive or negative? If there were indeed factors that were entirely unpredictable, then you can’t judge the punter for not forecasting them: nobody can read the future.
Perhaps a horse was severely held-up in a manner that wasn’t identified on anybody’s speed maps. Perhaps the horse – or even the jockey – suffered a minor injury at some point during the race. It affects the outcome, but how on earth could anybody predict it?
Reviewing races is the first step toward understanding why something panned out the way it did, yet a lot of punters don’t even take the time to do that.
Once you can effectively review a race, you’ll know the factors that led to the result. More crucially, you’ll be able to work out whether you should have been able to predict them. If so, you’ve made an error in your form analysis. The beauty of racing is that there’s always another race and you can amend and evolve your process.
Assessing a punter’s performance
When assessing a punter, you generally don’t know the exact method by which the analyst arrives at their conclusions. So how do you judge them on anything other than the outcome?
The key lies in concentrating on the long-term. You cannot judge any analyst’s performance on the back on one race, one day, or even one month. A poor performance may be purely variance at work.
So look at the long term: does the analyst have a reliable, genuine set of results that demonstrate an edge over the market? If they’ve been able to finish in front over the long term, it’s fairly good indicator they do!
So next time you throw that quaddie ticket in the air, or feel like hurling the remote at the TV? Keep outcome bias in mind: you might start to save yourself considerable heartache.
