Parasite Correlated With World Cup Success

mahiskali writes "A parasite commonly found in cats, Toxoplasma gondii, has an unnerving relation to World Cup victories by country. (This parasite was discussed here twice in 2006.) Toxo can be found in almost every type of mammal, from rats to humans. The overall goal of the parasite is to end up in a feline stomach, which is the only place it can reproduce. In other mammals, humans for example, the parasite heads for the brain. It is estimated that nearly 1/3 of the human population has a latent Toxo infection, with individual countries having infection rates varying from 6% (Korea) to 92% (Ghana). Countries with greater incidence of this parasitic infection in their populations tend to win more World Cups than those without. The article, written by a Stanford University neuroscientist, goes on to try out various rationales for such a correlation, ranging from increased testosterone to increased dissent of authority — all symptoms of a Toxo infection. Now we just need to find a parasite that causes an inability to referee properly, and we'll have this whole World Cup business all sorted out."

      Seriously, though, I researched toxoplasmosis a while ago (new kitten plus pregnant wife equals a million people saying OMG KEEP BABBY AWAY FROM KITTAH) and it's a very interesting disease.
      From wikipedia:

      The study suggests that male carriers have shorter attention spans, a greater likelihood of breaking rules and taking risks, and are more independent, anti-social, suspicious, jealous and morose. It also suggests that these men are deemed less attractive to women. Women carriers are suggested to be more outgoing, friendly, more promiscuous, and are considered more attractive to men compared with non-infected controls. The results are shown to be true when tested on mice, though it is still inconclusive. A few scientists have suggested that, if these effects are genuine, prevalence of toxoplasmosis could be a major determinant of cultural differences.

      It makes men more macho (the study does lose major credibility, though, by suggesting that risk-taking rule-breaking antisocial men are LESS attractive to women... what planet are they from?) and it makes women friendlier and sexier. Where's the bad?

      For this story we can look at it another way, and see that toxoplasmosis mortality shows the final four in this year's world cup should be Brazil, USA, Mexico and South Africa. Obviously that didn't happen, so this story is wrong.

      Obviously my evidence there is weak too, but it shows you can prove anything if you look at it correctly. In the case of this story, he cherry picked statistics that supported his thesis (which is also what I did). Of course the author knows this, and pointed out some contradicting data himself:

      The relationship is neither linear nor foolproof. Italy managed to win the World Cup in 2006, despite its relatively average infection rate of 33 percent. Certain African countries plagued with public health problems have astronomical Toxo rates. Yet the heavily infected players of Ghana, Gabon (71 percent), and the Ivory Coast (60 percent) have not yet managed to win a single cup. On the other end, England (6 percent), the U.S. (12 percent), and Japan (6 percent) are pretty OK at soccer yet have some of the lowest rates in the world.

      Basically it is a case of someone noticing an interesting coincidence and wanting to point it out to everyone, but it seems there's about as much evidence for it as there is for an octopus choosing world cup winners.

    The most common carrier of Toxoplasma gondii are cats. When a cat with Toxo injures a rat (but does not kill it) it usually passes the infection to the rat. The effect of the parasite on rats makes them slower and far easier for predators (like cats) to catch/kill them. Which, in turn, passes the parasite on to the cat. The cat then takes a swipe at a rat...and so on ad infinitum.
