But the home advantage is not limited to sports. Researchers have identified a more general effect as well: when people occupy spaces that they consider their own, they experience themselves as more confident and capable. They are more efficient and productive. They are more focused and less distractible. And they advance their own interests more forcefully and effectively. A study by psychologists Graham Brown and Markus Baer, for example, found that people who engage in negotiation within the bounds of their own space claim between 60 and 160 percent more value than the “visiting” party.
