Here's another person's take on this, though. Leon Tsao echoes Blake Donovan's ENFJ profile (I'm not indicating that he has ever read it; he's not referring to that profile), and he describes it as more of a delusive self-image, shared with ENTJs and based on tertiary Se.
While I personally have no idea whether he's right about ENFJs and ENTJs, I do think he's right about ENTPs and ESTPs, which he talks about later in the video. I might not actually be an ENTP, but I see it as a driving motive in the ETPs I've known.
Of course, that doesn't mean he's right about every type's "hidden agenda".
Here's what he thinks is ENFJs' (and ENTJs') hidden agenda:
They're afraid of appearing weak at all costs. So... I know quite a number of ENFJ males walk around like this (Leon puffs his chest up and pumps his arms up and down), and a lot of ENFJs I know try very hard to be "bad-ass". Like, a pattern I see is that they try to pretend to be goody-two-shoes in front of your parents, and then they pull you aside, and they're like, "Hey, by the way, do you know I'm a bad-ass?" And then they try... They talk a lot about getting tattoos and piercings, and then put up edgy pictures of themselves on Facebook. So, a lot of ENFJs I know are into kickboxing... (He says something about ENTJs for a moment.) It's not uncommon for ENTJs and ENFJs to have dating advice in which they tell you to be an animal on the prowl.
LOL
The part of the video from
1:49--2:56 is the part transcribed above and is the part that echoes Donovan's. (Entire ENFJ part is from 1:12--2:56.)
