The MBTI instrument sorts for preferences and does not measure trait, ability, or character. The tool is different from many other psychological instruments and also different from other personality tests.
The best reason to choose the MBTI instrument to discover your personality type is that hundreds of studies over the past 40 years have proven the instrument to be both valid and reliable; it measures what it says it does (validity) and produces the same results when given more than once (reliability).
