@Llyralen a better explanation and list of them. I can't remember all of them but there are new ones popping up that do not test accurately at all. It's like someone that made a test and didn't fully understand the MBTI or as someone pointed out does not care for the MBTI so it's more of a joke. Some of the worst can be a person with full Jung theory only and not going by what the other two scientists flushed out to become the MBTI it's known as today (Myers and Briggs personality test). The official one that the college gives you is probably one of the more accurate ones I've taken. Though free to take if you're at a university for being undecided, it's not free for the general public and costs money. Again Llyralen has a better list of them that are free.
I took an accurate function test recently and I was Ne, Te, Fi, Ni, Ti, Si, Fe, Se in that order.
But on this one, my Te was last place my Fe was pretty high. Both my Ne and Ni scored high on this test, my Ne edged out my Ni for first place as it always does because I'm heavily intuitive. My Fi edged out my Fe but both we're pretty high. I've never had Fe that high in my life. So that tells me the test makers have no clue what Fe/Fi or Te/Ti does and do not know how to properly test for them or ascertain a correct question to fit it.
When I retook it and answer all negative questions = heavy Te. so that means they think only assholes are Te people. That is not the case. All MBTIs can have assholes in them.
"You are generally attuned to what it means and takes to be of good moral character. " Strong NO
"You know exactly how to break someone. " Strong Yes
"You tend to communicate harshly or bluntly with others. " Strong yes
"You believe the world is ruled by the law of the jungle, that the strong prey on the weak." strong yes
This is what I got Te>Se>Ni>Ti>Fi>Ne>Si>Fe = ENTJ
And I don't disagree that Te can be blunt and a blunt force hammer but that's not all that it is. And if that's the only Te question the test maker thinks that it is, it's going to miss a lot of placement for people with Te as a third or second function. Do you understand?
Fe was all the lovey-dovey I'm so emotionally intuned with people. That's not just Fe. I know a lot of INFPs that can understand people and really empathize in a situation. So the test makers don't know how to properly test for Fi or Fe, hence I get both scored high.
It's a huge flaw in a test when two functions can't be properly tested for.
