Episode Overview

This episode of More or Less examines whether major football clubs like Manchester United and Barcelona are favoured by referees in the awarding of penalties—a common accusation after contentious moments on the pitch. Using data analysis, the episode explores this claim, unpacks the numbers, and broadens the discussion to how statistics can challenge perceptions, including a thought-provoking interview with renowned statistician Hans Rosling on global development.

Key Discussion Points and Insights

Are Big Football Clubs Favoured by Referees?

• Origin of the Debate:
  The episode kicks off with discussion about a recent controversy where Fulham was denied a penalty against Manchester United, sparking claims of referee bias in favour of bigger clubs ([00:13]).

• Widespread Perception:
  The narrative is echoed by football industry figures, notably Patrick Vieira, who claims,
  "When United played at home, they may get some advantage that some of the team will not get, but if you go into Spain, it's the same. If you're going to Italy, it's the same." ([01:37])

What Do the Statistics Show?

• English Premier League Data (2006–2012):
  Data from sports statisticians Opta:

  • Manchester United concede a penalty every 12 home games.

  • Fulham concede a penalty every 14 home games ([02:02]).

  • Chelsea, one of the most successful clubs, concede the fewest—one penalty every 18 home games.

    • Expert Interpretation:
      Bill Edgar, Times newspaper sports correspondent, explains:
      "Given that Chelsea have been among the most successful clubs over that period, you would expect them to have given away the fewest penalties. Simply, the opposition are generally weaker and therefore will spend less time in Chelsea's penalty area, so there will be less opportunity for them to win penalties." ([02:45])

• Spanish La Liga Data (Barcelona/Real Madrid, 2006–2012):

  • Real Madrid concede a penalty every 11 home games.
  • Barcelona concede a penalty every 10 home games ([03:25]).
  • Real Madrid both concede fewer and win more penalties at home (one every 4 games) versus Barcelona’s one every 5 games ([03:43]).

• Who Wins the Most Penalties in England?

  • Manchester United are awarded a penalty every 4.5 home games (second place).
  • Manchester City (Vieira’s own club) lead, awarded a penalty every 4 games ([03:43]).

Conclusion

• Summary of Findings:

  • The numbers do not provide evidence of systemic referee bias in favour of the biggest clubs. Differences are better explained by match dynamics (dominant teams’ opponents spend less time attacking, so fewer opportunities for penalties).
  • "So as so often, the data reveals the truth. It's Jose Mourinho's own team, Real Madrid, who have a better penalty average." ([03:35])

• Methodological Challenge:
  Host Tim Harford observes,
  "The only way to test for sure whether large football clubs are getting an undue advantage from the referees would be to somehow anonymise every club and every player and see whether it made a difference... I'm not quite sure how to conduct blind experiments for referees. Mind you, some football fans will tell you the referee is blind anyway." ([04:19])

Interview with Hans Rosling: Rethinking Global Development

After the football statistics, the episode pivots to an interview with Hans Rosling, world-renowned statistician and founder of Gapminder.

Key Themes

• Breaking Down Old Stereotypes:

  • Countries are not easily divided into “Western/developed” and “developing”—that dichotomy is outdated ([05:22]).
  • "We can no longer have two boxes in our head. One labeled Western World, the other labeled Developing World... Singapore has the lowest child mortality in the world and they are still a developing country." – Hans Rosling ([05:22])

• Diversity Within Continents:

  • Africa, for example, is too often judged by its worst examples, which is both inaccurate and, as Rosling points out, reflects a kind of racism.
  • "In Africa, you know, something bad happens in one country and you generalize it to the whole of the continent. Basically it's racist because you don't keep the countries apart." – Hans Rosling ([07:23])

• Progress and Nuance in Global Development:

  • Rapid development is occurring, notably in Africa, often unacknowledged by the West.
  • Ethiopian capital Addis Ababa’s fertility rate rivals that of Western countries, and Ghana’s life expectancy has reached 67 years ([08:10]).
  • "...we are projected to have an economic growth of 0.3%, whereas the entire sub Saharan Africa is projected to have 5% economic growth. And mind you, that is not from oil, that is from a diverse economic development now." – Hans Rosling ([08:35])

Memorable Moments

• Rosling’s critique of uncritical labels:
  "...Unicef, this wonderful United Nations organization, which I like so much stupidly, still labels South Korea developing country and unforgivingly label Singapore a developing country... This has to go. This has to leave." ([05:22])
• Challenge to Western pessimism about Africa:
  "No, it's not that I see it differently. It is differently." ([06:51])
• Sharp reminder of misplaced generalizations:
  "And that's not the way people look at Africa because they make a judgment of the worst of it." ([08:15])

Transcript

[A]

There are dozens of different podcasts now available from the BBC, including news, documentaries, science, business, arts and sport. The details of them all go to bbcworldservice.com podcasts this is more Or Less the programme in which the numbers always add up. We make an edition of the programme for BBC Radio 4, but this episode was broadcast by on the World Service. Hello and welcome to More or Less on the BBC World Service. We're your weekly guide to the numbers in the news and in life. And I'm Tim Harford. This week, we find out the secrets of life on earth with the superstar statistician Hans Rosling. But first, are big football clubs favoured by referees? That was the complaint after Fulham were recently denied a penalty against Manchester United. We don't have the broadcasting rights to play the key moment, but Ruth Alexander is standing by ready with an action replay.

[B]

Right, I'm Danny Murphy. Ok, I've got the ball, I'm running really fast. I'm about to shoot, but oh, no, Michael Carrick's after me.

[A]

Ooh, I want that ball. Penalty.

[B]

No, a penalty was not awarded.

[A]

Really? Hang on, are you speaking as Danny or Ruth?

[B]

Ruth. Now. So the referee did not award a penalty against Manchester United and it was controversial. Many fans of Smith smaller clubs would say it's because referees are biased towards big clubs playing in front of their home crowd. It's a widespread belief summed up by one of Manchester City's executives, Patrick Vieira.

[A]

When United played at home, they may get some advantage that some of the team will not get, but if you go into Spain, it's the same. If you're going to Italy, it's the same. And I think as a football club. Is he right? There's only one way to tell. Check the statistics and the sports data specialists at Opta have gathered the data for us every English Premier league game since 2006. And the answer is no.

[B]

So, on average, Manchester United have conceded one penalty every 12 home games since 2006, while Fulham have conceded fewer. Roughly one penalty every 14 games at home.

[A]

So if you're a team playing away, it's easier to get a penalty if you go to Old Trafford than if you go to Craven Cot.

[B]

Yes, but the team which have conceded the fewest one penalty only every 18 games is one of the top dogs, Chelsea. However, referee bias in favour of the big clubs isn't the obvious explanation, it seems here, according to a sports correspondent with a keen eye on the statistics at the UK's Times newspaper, Bill Edgar.

[A]

Given that Chelsea have been among the most successful clubs over that period, you would expect them to have given away the fewest penalties. Simply, the opposition are generally weaker and therefore will spend less time in Chelsea's penalty area, so there will be less opportunity for them to win penalties. But Patrick Vieira also complains the refs are biased towards the big clubs in Spain and Italy. And Real Madrid's manager, Jose Mourinho, is frequently up in arms over what he sees as bias towards Barcelona. So we asked the sports statisticians at Opta to look at every La Liga match involving Barcelona and Real Madrid since 2006.

[B]

And the stats show that Real Madrid conceded one penalty roughly every 11 games in front of their home crowd, while Barcelona conceded one in every 10.

[A]

So as so often, the data reveals the truth. It's Jose Mourinho's own team, Real Madrid, who have a better penalty average.

[B]

And Real Madrid didn't just concede fewer penalties at home, they won more too. Roughly one every four home games compared to Barcelona's one in five. And if you look at who's been awarded penalties in the English Premier League, there's an interesting story there too. Manchester United have been given one penalty every four and a half games they played at home, on average, putting them in second place. In first place is Manchester City. Yes, Patrick Vieira's own club. They've been awarded a penalty every four games.

[A]

Well, thank you, Ruth. Of course, the only way to test for sure whether large football clubs are getting an undue advantage from the referees would be to somehow anonymise every club and every player and see whether it made a difference. Orchestras famously introduced blind auditions where musicians played behind screens and they saw the number of women admitted rise sharply. But I'm not quite sure how to conduct blind experiments for referees. Mind you, some football fans will tell you the referee is blind anyway. Now, from using statistics to understand football to using statistics to understand the whole world, this week I've been speaking to a man who probably knows the world better than any of us. Hans Rosling is the professor of International Health at the Karolinska Institute in Sweden, founder of the Gapminder foundation, which promotes, as he puts it, a fact based understanding of the world through statistics. It's in his hands more than anyone else's that statistics truly come alive and tell their own story. If you want to understand the world you're living in, the world your children and your grandchildren will live in, listen to this.

[C]

We can no longer have two boxes in our head. One labeled Western World, the other labeled Developing World. And the very fact that unicef, this wonderful United nations organization, which I like so much stupidly, still labels South Korea developing countries and unforgivingly label Singapore a developing country. Singapore has the lowest child mortality in the world and they are still a developing country. And Qatar, which is the richest country, which has given us Al Jazeera, they are also developing. This has to go. This has to leave. And we have to realize that countries are on a line from in one end Singapore and Norway, and in the other end Congo and Afghanistan. And in that distance between Singapore and Norway being the most affluent and healthiest countries in the world and Congo and Afghanistan being the poorest and most deceased, most people live in the middle. That's where Brazil is, that's where Turkey is. That's where Indonesia is. That's where China is. That is where half India is. The other half of India is very poor, but moving also. So it's the whole way in which we sort it.

[A]

I think a lot of people have realized that places such as China, India and other major countries are developing very quickly. But many people feel a sense of hopelessness about Africa. But you see it differently.

[C]

No, it's not that I see it differently. It is differently. It has been put very nicely lately. Someone said we have to look upon Africa as we do with Asia. No one say I will not invest, nor would I like to go to holiday to Malaysia because there's such a war in Afghanistan. We have come to judge each country in Asia on their own merits. We know that Burma had a terrible dictatorship and that Thailand has a shaky democracy and that Vietnam has a clever communist party that is not democratic, but they are clever. And in Africa, you know, something bad happens in one country and you generalize it to the whole of the continent. Basically it's racist because you don't keep the countries apart. The number of children per woman in Addis ababa today is 2.5. The most educated part of the Ghanaian population have two or three children. Just. I actually looked at Mali, the tragic coup d' etat which was a major backlash in Africa. Mali has 50 years life expectancy and have 6 children per woman. Ghana has 67 years life expectancy and 4 children per woman. This means that Ghana is halfway between Britain and Mali. And that's not the way people look at Africa because they make a judgment of the worst of it. And we should be very humble in the European Union this year and next year because we are projected to have an economic growth of 0.3% whereas the entire sub Saharan Africa is projected to have 5% economic growth. And mind you, that is not from oil, that is from a diverse economic development now. And there are 17 countries in Africa which are above 5% economic growth. And I'm as a public health professor, I'm not so impressed by economic growth. But when I see that economy grow and the child mortality drop at same time, then something is truly happening. That's not happening in Gabon, for instance, but that's happening in Tanzania.
