15. Star Trek’s Spock – ISTJ
For those who swear by MBTI and its unerring accuracy, fictional characters to are assigned MBTI, based on their fictional behavior. And as with those of historical basis, there is little consensus as regards the type. Star Trek’s Mr. Spock is described by some as possessing an ISTJ personality (Introvert, Sensing, Thinking, Judgement). One assumes the designation is arrived at logically. He shares the type, according to some, with Sherlock Holmes, though others designate Holmes as an INTP (Introvert, Intuitive, Thinking, Perceiving). Different portrayals of Holmes earn different MBTIs, though, which makes him more difficult to categorize. Robert Downing Jr’s rendition of Holmes is listed as an ENTP (Extrovert, Intuitive, Thinking, Perceiving) for example. Since Holmes is fictional, one doubts he would mind the differing opinions.
Star Trek’s Lieutenant-Commander Data, an android, is considered by some to possess a personality type of ISTJ, similar to Spock and Sherlock. Surprisingly, the highly emotional Dr. McCoy, from the original series of Star Trek also shares the ISTJ designation, according to some sites. Perhaps the similarities in personality are one reason McCoy and Spock were frequently at odds with one another. Or should that read will be at odds with one another, as we’re a long way from the 23rd century. One may also assume that since Vulcans are trained in logic and the elimination of emotions that all of them share the same MBTI type. But that may be racist thinking. Fortunately, all Vulcans are fictional, at least to most people. There are deeper mysteries to ponder than their personality types.
