Can the Crowd Predict Soccer Matches?

One way to test the Wisdom of Crowds is to ask a simple question and see how a group responds. Surprisingly, even people with very little soccer knowledge can sometimes produce estimates that are close to reality.

A Simple Soccer Experiment

Imagine asking a group of people:

“How many total corner kicks will there be in tonight’s soccer match?”

Suppose the group consists of researchers, office workers, or friends who don’t regularly follow soccer. Some may watch the sport occasionally, while others know almost nothing about it.

Each person writes down an independent estimate without discussing it with anyone else.

As expected, the guesses vary dramatically. Some people predict only a few corners, while others expect more than twenty. Individual estimates are all over the place.

Yet when the guesses are averaged, something interesting happens.

The group’s average often falls very close to the number sportsbooks use when setting their betting lines.

Why Does This Happen?

This is another example of the Wisdom of Crowds.

While many individual guesses are inaccurate, the mistakes tend to balance each other out.

Some people consistently underestimate the number of corners.

Others overestimate.

When enough independent opinions are combined, the overall average frequently produces a realistic estimate of what usually happens in a soccer match.

This doesn’t require expert knowledge. It simply relies on the statistical effect of combining many independent estimates.

Sportsbooks Use Similar Principles

Sportsbooks don’t rely on random guesses, but betting markets work in a similar way.

As thousands of bettors place wagers, the betting line adjusts to reflect the market’s collective opinion.

By kickoff, the corners line often settles near the number that the betting market considers most likely.

This doesn’t mean sportsbooks know exactly how many corners will occur. It simply means the market has reached a reasonable consensus based on all available information.

The Crowd Can’t Predict the Future

Although the crowd often produces a good estimate of the average outcome, it cannot predict the exact result of any individual match.

One game might produce only three corners.

Another could finish with eighteen or more.

Soccer is influenced by countless unpredictable factors, including tactics, game state, weather, refereeing decisions, and random events during play.

Even the most accurate betting line represents only an expectation—not a guarantee.

Average Doesn’t Mean Exact

This is an important distinction for bettors.

A betting line of 9.5 corners doesn’t suggest that every match will finish with nine or ten corners.

Instead, it reflects the market’s estimate of the most likely range over thousands of similar matches.

Individual games will naturally produce outcomes far above or below that average.

That’s exactly how probability works.

What Bettors Should Learn

The Wisdom of Crowds shows that large groups can generate surprisingly accurate estimates of average outcomes.

However, accurate averages don’t translate into perfect predictions for individual matches.

For soccer bettors, this means betting markets provide a strong baseline for evaluating a game, but they cannot eliminate uncertainty. Every match remains unique, and unexpected outcomes are always possible.

The crowd can estimate what is likely to happen over the long run, but it cannot reliably predict exactly what will happen in the next 90 minutes.
