Today we are typing "Vision". This is obviously a pseudonym, and one which already tells you something about him. A recurring theme is his vision for the future, which he has thought about in quite a lot of detail (I followed up with him to make sure of this). This suggests an Ni triad type, seeing as his long-term plans are a conscious part of what is important to him (rather than an unconscious part as the suggestive function often is).
But what is his vision? The main part of it concerns him and his family, rather than realizing some larger vision for society. This would suggest Gamma rather than Beta. Vision places a lot of importance on relationships: someone who is there to "have your back" in facing the world and going through rough times (so, more SeFi than NeFi). He is willing to cut people off when called for, a typical Gamma (FiSe) sentiment. He isn't against being friends with people who have different beliefs as long as they support him and his goals — a pragmatic approach that suggests lower priority Ti and maybe higher Ne as well. He occasionally uses harsh language at other points to describe people who have done him some kind of wrong. "Get over it buttercup" — Gammas are quick to emphasize personal responsibility when things go wrong.
Vision has difficulty thinking of weaknesses and things he needs help with. This is very unusual and suggests maybe higher Ne and possibly Te. The one that he does mention is a lack of trusting others — again a typical Gamma trait (Ni + Fi), though not a weakness in the Model A sense. His strengths include farsightedness and tenacity: never giving up, eventually succeeding even if he fails multiple times. This suggests some access to both Se and Ni, so likely not Ni leading.
Beyond the responses to the questions, it's worth noting that Vision proceeds quickly, even impatiently, through the questionnaire, often giving brief answers when he feels like it. Most people choose to use the full time allotted, whether because they want to get their money's worth or because they enjoy talking about themselves. His affect is bright and positive, suggesting higher Fe. He describes being "needlessly enthusiastic" and social around strangers which suggests bold and possibly weak Fe. All in all it's very difficult to see Vision as an introvert and especially an introverted Gamma.
What he dislikes in people is essentially the opposite of his own long-term thinking, which he describes as hedonism. He doesn't care for simply "enjoying" himself mostly, he would rather "use [his] youth effectively]" and "get power at the right time". While hedonism can be related to either Se or Si, in this case it is clearly about Si (+ Fe), in opposition to Se and Ni.
If it wasn't clear yet, the most obvious typing for Vision is LIE — the only type with bold and valued Se, bold Fe, and strong Ni. TeNi is further supported by his enthusiastic response to the "starting a business" question: not only does he seem to have thought about starting a business before, for the lottery question he offers a breakdown with specific numbers (!). For the business he would do the "elbow grease" at first but eventually transfer the day-to-day management to someone else, and possibly sell it, suggesting a disinterest in Si. It's also notable how he doesn't have a strong preference about what type of business to start, focusing instead on capitalizing on whatever economic opportunity exists, e.g. selling hand sanitizer for the COVID pandemic. (Financial) autonomy comes up here, a common Gamma theme. He describes jumping into the stock market as a significant step in his life, where he took a risk despite the naysayers.
Even though Vision mostly seems to be a clear LIE, it's worth considering possible alternatives. The main ones that come to mind are EIE and SEE. He is unusually frank on the topic of relationships, suggesting maybe higher Fi. But SEE doesn't really work for multiple reasons: his focus on the future, just walking around and thinking while on vacation, being seen as a cool-headed person, etc.
As for EIE: He has no shortage of large-scale judgments about society or "this culture", and does wax romantic sometimes — even the name "Vision" is arguably a bit dramatized. But it's hard to see an EIE emphasizing personal loyalty and character judgment to such a degree, not to mention the economic focus. He also does criticize people for being overly autonomous, for not caring about others — despite his own emphasis on autonomy. But I'm prone to viewing this kind of social responsibility as simply a more mature, self-reflective Gamma outlook. And he doesn't care about, or even like, getting attention either.
Vision's attitude towards conflict is maybe unusually restrained for an LIE — he says he generally walks away from it, and doesn't get angry much in general. (But he contradicts this somewhat by saying that he would have gotten in a lot of trouble at high school.) It doesn't contradict the overall picture of Se valuing extrovert, but it's probably more likely for an Fi valuer, and someone with greater Ni. So it would suggest EIE and SEE even less so.
Vision, more than most people, fits the classical idea of the LIE's "unbridled optimism". He has no shortage of Ne: the purpose of life is "to make something better". But other LIEs are much more negative and skeptical, which is why I find the classical descriptions misleading. Nonetheless most would likely agree with his principle: "I live my life so I don't regret things."
