Why an honest account of an accident can sound like an excuse
Listing the causes of an accident is how safety experts find the truth. To an untrained listener it can sound like dodging blame. Four biases explain why.
Mostly, no. Across hundreds of studies, people who work toward a shared goal learn and achieve more than people set against each other. When competition does lift performance, it tends to cost more stress for the same gain.
Many schools, workplaces and sports clubs run on a simple idea: rank people, reward the top, and everyone tries harder. Leaderboards, class rankings, sales contests and "employee of the month" all assume that beating someone else is the strongest motive we have.
Researchers have tested that idea for about a century, mostly in classrooms, because classrooms make it easy to set up the same task under different rules.
Psychologists David and Roger Johnson, at the University of Minnesota, sort any task into one of three structures:
| Structure | How it works | Example |
|---|---|---|
| Cooperative | You succeed only if the group succeeds. | A team project marked as one piece of work. |
| Competitive | You succeed only if others fail. | Marking on a curve; only the top three get a prize. |
| Individualistic | Your success has nothing to do with anyone else's. | Pass if you reach 70%, whatever others score. |
In 1981 the Johnsons and colleagues pooled 122 studies, with 286 findings, comparing these structures in North American samples. Cooperation produced higher achievement and productivity than either competition or working alone.
In 2008 a larger review focused on early adolescents: 148 studies, more than 17,000 students, in 11 countries. Cooperative goals went with higher achievement and with better relationships between students. The two moved together: students who got on better also learned more.
A 1995 review by the same group pooled 46 problem-solving studies published between 1929 and 1993. Cooperative teams beat competing individuals on every type of problem: written and spoken, mathematical and practical, clearly defined and open-ended. The result held at every age and in weaker and stronger studies alike.
Two cautions. First, the Johnsons also train teachers in cooperative learning, so they are not neutral observers, and much of the research comes from their centre. Second, classroom studies measure classroom outcomes. They say less about, say, a sprint final. Critics such as Alfie Kohn, whose 1986 book No Contest reviewed the wider research, argue the pattern holds well beyond school; that remains an argument, not a settled finding.
A 2024 study at the University of Turin tested the question in a new way. People did a demanding attention task in virtual reality, either cooperating with a partner or competing against one, while researchers tracked heart rate and asked how stressed they felt.
So competition can work. It just charges a physical price that cooperation does not. The study ran in the lab over short sessions; what that price does over a school year or a career nobody has measured this way yet.
The research does not say competition is always bad. The Turin study found it lifted performance, and games and sport can be fun when losing costs little. The evidence argues against competition as the default way to hand out grades, pay and respect, because the same gains come cheaper through cooperation.

Small rewards can double blood donations or build kids' eating habits. A fine can make parents later, and cash can halve donors. What decides which.
A famous 1989 study had judges set bond nine times higher after thinking about death. Big replications since then paint a weaker picture.
