Huang Kuang-kuo, a professor of psychology at National Taiwan University, affirms that people who like guess-fingers are usually affable and outgoing. "Guess-fingers is a social activity that brings interpersonal relations closer. Reserved or introverted people have a hard time handling it."
台大心理系教授黃光國便認為，喜歡劃酒拳的人多半較為豪爽、四海，因為「酒拳屬於拉攏人際關係的社交活動，一般含蓄內向的人很難習慣於這種開放式的溝通。」
