England has a psychological advantage over Argentina heading into their World Cup semifinal match on Wednesday, according to psychologists. Experts from Eras developed a "Psychology of Winning the World Cup Index" that evaluates teams on mental resilience, leadership stability, and performance under pressure.

According to the index, England holds the mental edge over Argentina. Dr. George Sik, a psychologist at Eras, advised England to "stay composed under pressure and avoid being drawn into an emotional battle," noting that "Argentina thrive in high–stakes knockout matches and they're experts at managing momentum." He emphasized that England "needs to remain patient, keep their discipline, and take their chances when they come" to reach the final.

The index considers five measures: the total number of red cards received, average manager tenure, average goals scored in the last 15 minutes of matches, the number of knockout stage appearances, and performance under pressure. France tops the overall list, followed by England, Spain, and Argentina.

Argentina is ranked last primarily due to its disciplinary record, having accumulated 10 red cards, more than three times England's total. In contrast, France leads the index despite having six red cards, benefiting from a long average manager tenure of 1,812 days and a strong performance under pressure score.

Spain is third on the list with one red card, demonstrating that "disciplined possession–based football can also translate into pressure resilience." England ranks second with three red cards and a performance under pressure score of 5.99 out of 10.

Separately, research from the University of Reading has identified an optimal penalty-taking technique. Scientists analyzing various methods found that shots are most successful when they are "high and wide," similar to those taken by England's Harry Kane. The study advises against "safe" shots, which are more likely to be saved.
