It is difficult to determine which MBTI type is most skeptical of MBTI results as skepticism can vary greatly among individuals within each type. However, based on the information provided, it appears that INTJ individuals may be more skeptical of MBTI results. This is because INTJs are naturally skeptical individuals who prefer to focus on facts and proven methods, and will do plenty of researching before just believing something they hear. They are not the type of people to take all information at face value and prefer to analyze and question information before accepting it as true.
