The difference between "sensors" here and in real life is I get to see what the introverted ones have to say and how they think about things. People in general are more introspective in online forums.
But as far as character and intelligence and all that, unlike seemingly the majority of "intuitives" on type forums, I have had plenty of good experiences with "sensors" in my life and already knew what a gift they can be. I don't think the "sensors" here are smarter than the average "sensor" in any way, shape, or form. That is one thing that is not different, they are every bit as smart in real life, and there are dumb "intuitives" everywhere. I have had way too many smart "sensor" friends and family and even co-workers to buy that. I have known people from all over the world, urban and rural, educated and not at all. I have known dumb people and smart people, and most of the smart people I have known have been "sensors" (probably because I haven't known too many "intuitives" very well, just 5, and yes they were all more or less smart, even if at least one was very socially stupid).
The only reason I am participating in this forum at all is the large minority of "sensors" here. It is such a refreshing change. The various numbers of "sensor"-haters on the internet (usually NPs I am sad to say) really, really tick me off. It's funny, when I found this forum I was prepared to come in fighting because I was feeling feisty and the last forum I left was intpcentral, which is filled with very stupid people who happen to be "intuitives". But I see I don't have to fight.
And ESs will discuss this kind of thing (well, I don't know about ESTs, but I know a lot of ESFs), but not usually by typing in an online forum. Or reading it in a book. They more like talking about psychology stuff in an offline kind of discussion.
