On the other hand I would say that E7s are cocky in a charming manner, whereas E3s are egoistical.
"Cocky" is a great adjective for 7s; I think it's where [MENTION=5684]Elfboy[/MENTION]'s coming from about 7s wearing their swagger on their sleeves, and thus, perhaps, being more visible in their self-centeredness than type 3s. I don't know about you, but I tend not to worry too much about whether someone might be turned off by my personality. For example, I'll make extremely sexual jokes in the presence of somebody I just met (provided the circumstances are not professional), and then I'll giggle hysterically at my own comments because I really can't help myself. (Think Craig Ferguson, and the way pretty much everything on
The Late Late Show deteriorates into a perv-fest.)
I think 3s are more inclined to concern themselves with first impressions, and would therefore be more likely to hold off on revealing parts of themselves until they've decided it's appropriate. They probably come off as more polished - more widely liked, more universally charming. Sure, there are a lot of people who seem magnetically drawn to my, uh,
unique approach to socializing, but I would bet that it rubs just as many the wrong way...and I don't care. I think 3s are more likely to care, possibly a lot.
In my personal experience, 7s might wear a playful self-assuredness on the outside, but it's usually harmless - and that's why I don't really care for the use of the word "narcissistic" to make generalizations about the type. I've seen true, disorder-scale narcissism and it's abusive - very, very damaging, caustic, and scary. It's not fair to label 3s with the word, either, and I know that...but two of the three people I've known with varying degrees of the problem were indeed 3s, and their traits aligned so much more strongly with Elfboy's descriptions of entitled-just-because.
So, basically, my theory is that if we have two unhealthy individuals (one a 7 and one a 3), the 7 would be more outwardly cocky and abrasive whereas the 3 might seem very classy and cool on the outside, yet obsessed with themselves and their images underneath, cutthroat.
On a side note, I don't personally relate to the idea that 7s think everything should just be handed to them. Not at all. I did have a bad childhood, and yeah, I might be trying to compensate for years of misery to some extent, but I still expect to work for what I want. I'm an opportunist, a playmaker. See something you want? Then go for it. But you don't deserve to win if you're not even willing to play the game.
