PeopleMaps has many aspects in common with other well known profiling systems and also a number of important differences, most notable is the PeopleMaps questionnaire which overcomes many of the issues that traditional testing methods fail to address.
For example, MBTI comprises 94 questions in the G-self scorable questionnaire and over 100 in others; PeopleMaps questionnaire is designed exclusively for the internet and comprises ten questions. Kline (1993) states that even with as few as ten items the mean item correlation can be very high since the shorter a test the more useful it is. Tolerable reliability is especially possible if the items are measuring a common core.
At the date of writing 1.2 million people have completed the online version of the questionnaire which comprises 10 questions and the results have proven to be consistently accurate. The short questionnaire can improve accuracy as there is no time for boredom to affect the results.
