The Hitchhiker’s Guide to the Galaxy, Douglas Adams

Ne: Ford wants to do everything, see everything and he sort of gets his wish –aside from the boring 15 years he spends trapped on earth. His writing (for the Hitchhiker’s Guide) is rambling and doesn’t stick to one topic or even come to conclusions most of the time. He improvises a lot, trying to drive ships that he’s never driven before and almost getting people killed. He hitchhikes the galaxy without a map or plan, practically bluffing his way through the majority of danger.

Ti: When thrown out of an airlock by the Vogons, Ford is hardly frightened, and responds in an apathetically go-lucky way to Arthur’s panic. Rather than comforting his friend, he gives a detailed, emotionless briefing of what will happen to them “the hatchway in front of us will open automatically in a few moments and we will shoot out into deep space I expect and asphyxiate.” Despite his ability to improvise and come up with out of the box solutions, Ford isn’t particularly action oriented and in fact, would rather sit around and wait for luck than come up with a strategy to get out of danger.

Fe: Ford doesn’t really go around trying to save anyone or really help anyone and that includes himself. Much of the time, he’s perfectly unphased by the idea that he might die if he doesn’t act, which leaves Arthur in a panic much of the time. He’s not easily controlled by his emotions, which can be a good thing (in allowing him to not freak out in dangerous situations) and a bad thing (in making it so that he doesn’t feel the need to act in order to protect himself and others).

Si: When trapped on earth, Ford goes for a name that he thinks will blend well with the planet’s culture (and fails at it, since he picked the name of a car, not a person). When in a dangerous, stressful situation, he often assumes that there is no way out (Vogon poetry? We’re dead! Airlock? Oh, too bad. etc.)
