That's mainly because of the writers and not because of Lisa. She used to have friends in the first few seasons, but for some reason they weren't her friends anymore after that. Lisa made some new friends in Summer Of 4 Ft 2, but we never saw them again in any of the newer episode. I think that's the last episode were Lisa had some friends of her own age...

You could say Lisa has some older friends. In the latest episode (Moe 'N' A Lisa) she helped Moe discovering his inner poet and Moe liked her, so you could say Moe is a friend. The same goes for Willy (My Fair Laddy from season 17) and probably some other examples I can't think of now

IMO, the greatest Simpsons episode EVER. Anyways, Lisa has a few good friends. Some that were not mentioned yet are: Allison, Alex, and Janey [I guess]. Even though

Lisa seems to get along well more with adults than her peers. Case in point: Mr Bergstrom, BGM, That museum guy in Iconilast. There was an episode where Lisa was at the libary and seemed to know some of the people there.

^ he's right

and she does have friends, like janey for example... lisa and janey hang out at times but we haven't seen them hang out together since the current season started

nelson muntz... they went out together, and nelson helped lisa get back on sherri and terri.

homer: they do some stuff together at times like when the painted houses fot the destitute, they do father daughter activites, and homer helped lisa with her scinece project(the nuclear reactor)

these are just SOME of the people i can think of right now

That is very true, wise people know that quality > quantity.

And yes, Bleeding Gums deserves to be mentioned He was a great friend of Lisa's, even if he made only several appearences before his untimely death.

My personal opinion about Lisa's lack of friends is simple. Other kids alienate her, while adults don't take her seriously. This sounds sad and rude, but this is true, to my opinion. Other kids don't want to have friendship with Lisa, because she has different values and principles; sometimes they don't even understand her. As for adults... Springfield is Springfield, and the situation when even an adult doesn't understand Lisa and therefore doesn't take her behavior seriously, happens quite often. Lisa is smarter than many of people around her, that's why she is alone. I want to believe that that would change in her future, when she grows up a bit, but it's very likely that even when she still will be a lonely girl.

Lisa is "doomed" to be ahead of her own time, and such people always have hardships in relations, especially in a world like Springfield: more so, cause Springfield is a theater for the most mediocre and lowest-common-denominator personalities that roam this green earth.
It isn't as simple as "being mature". If she was just more mature for her age, she wouldn't have problems with older people. The problem that keeps her from having any friends (other than the script) is in my opinion that she is just "too unique". She is such a fine blend of the better (and why not, even worse) things taken from every age... that she's just like a snow flake. You might find some that looks *just quite like it*, but it's still different.

I hope i made sense

You're right. I do so, too. If you're intellectually talented, gifted or whatever the right translation is older people understand you better. But can't have any friends because she lives in Springfield. The charas at this club (Database, E-Mail...) are designed after the typical prejudices. The ones that I know from the Mensa Germany camps are different. They listen to each other and discussions can really be fun! There is a famous quote that says "In a room with 12 Mensa members discussing you can at least find 13 different opinions. So it's not directly cause she's a kid.

That from my part. Remember the Simpsons are cartoon and Matt and his guys have thought about in what situation they place Liz. She's not at lucid dreamin here

I am actually sure she wouldnt appreciate you beating up people for her. Protecting her from an attacker is another matter but just beating up people isn't what Lisa is about.

In the long run I am sure Lisa would frown on violence against people in her name. I honestly don't think Lisa has enemies as such (except probably Sideshow Bob). There are people that she is not keen on and those who are not keen on Lisa.

I think Lisa is the kind of person who people secretly want to be friends with, but embarassment and peer pressure from classmates prevent that. I would think a few of her classmates actually look up to her.

When Lisa gets older she will have no shortge of friends. She has one of those personalities which attracts people, as an adult people will of grown up and realise what a nice person Lisa is.

If only Lisa was aware we existed lol.

I guess the writers never show her with them, but she does have them (see "Flaming Moe's" as an example)...maybe that's a missing piece of new episodes. Same for Bart, they rarely show him with anyone else except the family these days.

You speak so wisely...I totally agree

"I think Lisa seems to feel more comfortable in company of older people. Remember her Mensa membership? But since she is only a kid she can't have friends like that yet."
I think what is this in fact? I mean such her adulthood. Is it something caused by her natural loneliness, or it's just a consequence of her bad relationship with peers? And therefore she searches for communication in company of the old people? Anyway I must admit she's really a kind of hermit beside her classmates. They all just a kids with their own lacks, while Lisa searches some eternal truths in their behaviour. And of course she couldn't find it. Same with the family.
