Okay, hope you don't mind my copying the other thread's idea....Here's my version for ILI. See if you agree with these.
The following types of people whom I think are ILI aren't all mutually exclusive (some people may have traits of more than one of these). They're very similar in that they're more approachable than they appear to be:
1) Highly talkative and somewhat clingy. Talks about some area of knowledge at length, and is difficult to interrupt. Has low awareness of whether other people are interested, but very easy to get along with.
2) Has strong opinions; likes to debate in a lawyerly style; amenable to a good argument; has high logical standards and avoids being too "soft."
3) Artist type; writes stories, takes pictures, writes music, etc. Usually somewhat perfectionistic about his/her art. Interested in abstract/geometric patterns. Tends to dabble in lots of things. Usually doesn't take a lot of initiative in doing something with his/her creations.
4) Straightforward, easy-going and friendly; usually involved in some technical field. Creates the appearance of organization and control but relies on others to supply initiative.
In addition, here are some types of people who may be ILI according to some views, but are more probably other types:
a) Engineering mentality; interested in making money; obsessively normal; lacks own personality; tends to follow the group in whatever it does; lacks convictions; low sense of morality. Possibly SLI? (or ILI but psychopathic? Tcaud-style crosstype?)
b) Heavy planner; researches everything in advance; annoyed if things don't go as planned; lives life as a sequence of planned actions; concerned with planning actions and averting what might go wrong; action-oriented; highly organized but likes to relax (usually relaxation time is scheduled). Business-oriented. Possibly LSE, LIE, or SLI?
c) Hard-working scientist type; seems to know everything; rather eccentric; very commanding and directing. Good at figuring things out; sometimes jumps to conclusions. Possibly LIE or LII.
d) Flaunts impression of knowledge (without necessarily demonstrating it); intellectually aggressive; power-driven; arrogant-seeming, uses unfair means of attacking opponent or making opponent look bad; implies that opponent is stupid. Probable LSI.
