Bracketology: What the data says about why people love an underdog

People love the underdog for a variety of reasons, even when the data shows that the underdog is unlikely to win. why?

The answer to that question is, to some extent, built into the annual spring ritual millions of people engage in: bracketing the NCAA men’s basketball tournament.

The NCAA’s “Selection Sunday” will be held on March 17, St. Patrick’s Day this year. This is the day the NCAA finalizes the brackets for this year’s March Madness basketball tournament. The next morning, millions of people download, print, and fill out these boxes. All are anticipating a “Final Four” and some are hoping to win a few bucks.

Brackets are very simple. The 64 men’s college basketball teams are divided into four regions, and each region’s games are structured based on the team’s ranking (1st vs. 16th, 2nd vs. 15th, etc.). Each game is an elimination game. Winners advance to the next round and losers go home. The tournament will culminate this year with the “Final Four” at State Farm Stadium in Glendale, Arizona.

So how do most people fill in the brackets?

The easiest approach, especially if you don’t follow the NCAA closely, is to always choose the higher ranked team. In fact, higher ranked teams win more often, especially in the first round, where big names like Duke and Gonzaga could face smaller schools that just barely made it to the tournament. Some bracketing websites like ESPN always give you the option to select the higher ranked team by default.

But this is not something many people do. Instead, pick the underdog to win, at least in some matches.

This is partly due to the fact that it is much more exciting to take risks and bet on low-probability upsets.In fact, people A general tendency to root for the underdog. Do you remember the first time you saw the movie Rocky? Didn’t you expect Apollo Creed to lose to Rocky Balboa? Vulnerable people have the right to appeal by proxy.

Another reason people tend to root for the underdog is that making the same choices all the time can be boring. Decades of research It shows that people change their decisions over time, even to undesirable outcomes, because they get bored or tired of repetition. But they also do it for social reasons. That is, to let yourself or others know that you are not the type of person who always does the same thing. In fact, the desire for variety even causes people to change their decision-making strategies (for example, from choosing the cheapest product to choosing a more expensive product). Just “for a change””

These are all strong psychological reasons to expect an upset at some point in the March Madness bracket.but when Are people more likely to predict unlikely outcomes, such as picking the underdog to win?

What we carried out was scientific research The paper, published in the INFORMS journal Management Science, found that people were more likely to make predictions when they were made later than when they were made earlier. Applying this to March Madness, our findings show that, for example, if people predict the outcome of a game third, they would rather predict a lower-ranked team (e.g., a 10th seed than a 7th seed). ) suggests that there is a high possibility of choosing . than the first bracket.

This is called the “predictive order effect,” and it’s caused by how people think about probability on a daily basis.They are tend to treat Separate events as if they were related, even if they are not. If he tosses the coin three times and it comes up heads the first two times he flips it, it seems unlikely that it will come up heads three times in a row, so the coin “should” come up tails the third time. You may feel it instinctively. But in reality, each coin flip is statistically independent or unrelated to the last coin flip. The probability of heads (or tails) on the third flip is the same as any other flip: 50%.

The same process can be applied to the “March Madness” bracket. When predicting the winner of the first game, people act logically and are very likely to pick the favorite. However, they do not ignore previous choices when making subsequent predictions. Rather, they consider the results of all the matches together and think, “This is a march.” Insanity There’s a reason for that – an upset is bound to happen at some point! ” Having already decided the winner several times, people tend to predict that the underdog will win in later matches decided by chance.

The NCAA Men’s Basketball Tournament has exploded in popularity for this very reason. Every year, at least a few underdogs win the match. It’s inherently difficult to predict exactly which team will be on when.And while science can reveal when and why people predict upsets will occur, the only thing that hasn’t been figured out yet is the code for filling in the perfect bracket (and maybe it’s never).
