Ubonwan is a Thai academic who wrote a 400 page doctoral thesis on the 9 characteristics of the Thai and why that contributed to the total failure of the early Christian missionaries to convert the Thais. It is a thorough examination of the subject. The list of references is itself 10 pages long!Ubolwan describes the characteristics as: Ego orientation, Grateful relationship orientation, Smooth interpersonal relationship orientation, Flexible and Adjustment orientation, Religio-psychical orientation, Education and competence orientation, Interdependence orientation, Fun and pleasure orientation, and Achievement-task orientation. Matt's "Meekness in Thai Culture" shows in just 24 short pages that her characteristics are the same cultural and lifestyle aspects of the Thai that he describes in his books. Matt gives many real-life examples in a readable format . Doctoral theses do tend to be harder to understand though covering the same ground. Ubolwan had to be more acaedmic in order to get her doctorate.
