As for the first one, my main reason would have been quite shady... Your description made me think of Barney Stinson from How I Met Your Mother. I believe he's an ENTJ with hyperactive Se, who acts like a ladies' man primarily to satiate his mastermind tendencies, and in discussion his TJness becomes pretty obvious. Also, the ESTP guys I know are usually extremely friendly, fun-loving creatures (Fe) who typically don't try to show others who's the boss. I considered ESFP as well but I've seen ENTJs 'masking' as both ESFPs and ESTPs to be more successful in society, so ENTJ seemed like a better guess.
As for the second one, to be honest I really don't think that routine and strict schedule equals J. I think that hyperactive Tertiary Si can provide for it just as well. I've actually met more INxPs who were pretty in love with their quirky little routines than INxJs. Do you think that your friend's schedule actually has any point (it is practical), or does it just seem like a quirk? Besides that, the sense of humor you described sounds totally Ne to me. "For example, he will give you step A and B of the joke, and it's up to you to infer steps C, D and E by yourself based on the situation." - where is this Ni? Playing with associations is much more typical for Ne. Plus, "finding logic to justify everything" is much more Ti than Ni+Te. Are you really sure that your friend is an INTJ?
As for the third one, I thought ENTP was pretty obvious, as the description sounded exactly as my two ENTP friends.
As for the last one, it sounded exactly like the ESFJ 'stereotype', but I've also met a fair share of ENFPs who were all 'nice to your face' but talked about you behind your back the next minute. Some ENFJs I know do it just as skillfully. Also, the passive-agressiveness doesn't sound too Fe-Si imo. (The ESFJs I know are rather plain aggressive ) But the desire to control her boyfriend does sound J, and you didn't offer enough N qualities for her to come across as an N.
For #1, one of three things could've happened...
1. I did a shitty job describing him
2. People did a shitty job typing him
3. He tested wrong
(4. A combonation)
His strengths reported from the humanmetrics test were:
Granted, I'm an INSANELY strong P, and I managed to score J on that test. So eNTP is also possible.
The others were pretty good!
Yeah, you didn't describe #1 very well. You went on and on and on about Se and never mentioned anything about Ni, or even Te.
If you could be anything you want, I bet you'd be disappointed--am I right?
