Numbers are generally thought of as an accurate means of describing the world for records and communication; but equally important to communication is the interpretation of the message, the accuracy of which has long been subject to scrutiny from the field of cognitive psychology. Research regarding our ability to discriminate numbers based on value has found that, within multi-digit numbers, latter digits influence our decision making even when only earlier digits are sufficient for the judgement, meaning there potentially exist some inefficiencies about converting numbers separated into different powers of ten (the one, ten, thousand digits, &c.) into the singular value they represent. To further examine this potential, the behavior of professional athletes are examined relative to the score they hold. Specifically, the average number of scores a professional badminton player lets their opponent score is calculated for each score the player may have; and the results show abnormal player behaviour when they have the score of 4 and 10 despite those scores having no actual importance to the game. Chinese and Japanese players, with a culture considering the number 4 to be inauspicious, are found to be the main contributors to the abnormalities at that score. Leaving abnormal behaviours at the score of 10 unexplainable except with a misinterpretation of its value. Even though current understandings are still vague, this demonstration of the mental failure to interpret numbers still has important implications for the studies of human error and also the discipline of human-machine interface.
