Jan Gill, an experimental psychologist at Queen Margaret University who helped establish that people have a tendency to overpour, agrees that Attwood and colleagues have shown an interesting effect of glass shape on how fast people drink. However, several aspects of the study give her pause. For example, she thinks that the inclusion of people who drink up to 50 units of alcohol per week -- roughly 12 liters of 3.5% to 4% strength beer -- is pushing the limit on what constitutes a "social beer drinker." At that level of consumption, she thinks people will drink quickly no matter what because they're "just drinking to get drunk."
