Edit: Since there are many comments, I would like to clarify my statement. I meant that you should rather trust scientists, that the earth is round / that there is a human-made climate change, etc. and not listen to some random internet guy, that claims these things are false although he has made no scientific tests or he has no scientific background. I know that there are paradigm shifts in science and sometimes old ideas are proven to be wrong. But those shifts happen through other scientific experiments/thoughts. As long as > 99 % of all scientists think that something is true, you should rather trust them then any conspiracy theorist...
Not being able to entertain ideas. "What would the world be like with 100% renewable energy?"
"Would basic healthcare for every person help our country?"
I tried to explain the 4 day work week to someone that gets paid by the hour. You make the same money but work 4 days a week instead of 5. Insisted he got paid less. Had to explain like a Bingo card with a Free Space, 1 day he is paid even if he stays home.
Being a republican. Sure there are some educated grifters who decide to label themselves as republican, but your average republican voter is a mouth-breathing fucking idiot.
Not being curious. Education should never stop. You should constantly be seeking intriguing books, new ideas, different perspectives. Once you've lost your curiosity or pridefully believe in one opinion and one way of thinking, no matter your schooling, you have at that moment become poorly educated.
"Whataboutism", or if you are unfamiliar with the term:
"The act or practice of responding to an accusation of wrongdoing by claiming that an offense committed by another is similar or worse"
People that use this mechanism are "poorly educated" and unable to hold a conversation and they should just be mocked by whatabouting even harder, so they can maybe understand that they're dumb and that's not how you should debate.
Example of the last argument I had recently with my dumb c*nt father:
Me: You shouldn't idolize that politician, he evaded literally billions in taxes and that befalls on citizens like you
Dumb c*nt father: Yeah? And what about that other politician?
Ironically, defending arguments using scientific studies and experiments, but not being able to think critically about the methodology used or what the results mean. Too often people will cite scientific literature based off the title and MAYBE skim it. Trying to have a discussion with them will usually result in them calling you anti-science.
A good example is the pseudo-scientific belief common within incel circles that women can store and absorb dna from past sexual partners and that their children can then have more than one genetic father (an excuse to shame sexually active women while fear mongering about cuckoldry). If you track down the source the study actually explicitly explains exactly why this isn't the case.
Being poor or lower middle class and voting for right wing/conservatives. You essentially give away your hard earned money and give it to ultra rich and worsen the quality of your life.. usually because the right wing scares people to be afraid of other people and new phenomena.
Any reference to "common sense", which really means "what I believe". Violating it is used as a universal rebuttal for any intellectually sophisticated argument.
I'm going to interpret poorly educated as badly educated as opposed to just not.
Imo the best sign of someone who has been brought up wrong is a total inability to tell the difference between what is legal and what is moral. Don't smoke weed because its illegal. Those homeless people shouldn't have slept outside if they didn't want to be arrested. Nazis should be allowed to march in the ghetto. I've heard all of those from people that have been raised wrong. They don't have any capacity for care, and they're basically just robots fullfilling whatever function they've been told is expected of them. Their hobby is watching tv. They have a wife that they never talk to.
Insisting things like tax returns or household maintenance should be taught in school.
The goal of Education is not to train you to fit into the system you happen to grow up in, but should provide the foundation (litaracy, STEM, art …) and awaken the curiosity in yourself to become lifelong learner.
That will develop society, and not a bunch of drones doing their tax returns and changing tires every season.
It depends on how you interpret "educated". If including things that aren't learned on school: I think that fallacies, rushed certainties and decontextualisation scream "this individual was so poorly educated that they never learned how to think."
I think that everything else can be derived from the above, shitty moral premises, or a mix of both.
People who think their dialect or language style is grammatically correct and others are wrong, because they don't personally known the grammar rules of any other dialect or language. They don't understand that language is alive and evolving and that the purpose of language is communication.
Personal use of proprietary software in the 2020s.
Or running a company to be completely dependand on dozens of unreliable and expensive proprietary software vendors.
Might not be a popular take but having an undefendable position like creationism does not necessarily mean "poorly educated." There are apologists who have learned proper reasoning skills and use their education to bend reality as much towards their will. I think most people would consider Jesuits and the like to be very educated but also very wrong.
As far as signs that someone is poorly educated, there are people who make up "big words" to give the impression of having a better education to other poorly educated people. Which backfires when someone with an actual large vocabulary walks into the room.
regurgitating talking points from a third party and the inability to distinguish between divisive issues and issues of difference. I
am a college professor and pastor and when I teach theology there is a crazy high instance of people who just spit out exactly what their favorite celebrity pastor says and immediate decide that it trumps whatever you are saying. Then they are unwilling to yield any bit of their position and get offended that you disagree.
disagreements do not need to be so divisive. The constant need for affirmation shows that you actually have no idea what you are talking about
Went on a trip a while back with a relative, here are some of the things that they belived/behaved like(sorry for the long text):Needless gossiping and thinking that other people's achivements threaten your credibility. Anger/apathy/being dismissive as default, snarky useless remarks, belittling other people any chance possible, trying to seem superior through "presenting intelectual", playing "the devil's advocate" just to look edgy and be unnerving, beliving propaganda over science, not apologising when needed, lacking self awareness and being selfish constantly, not going to therapy&health check ups, making poor spirited jokes about other people, not respecting people's space, touching them without permission,being disrespectful on purpose to other people(and to yourself), and the phobias(homophobic, biphobic, transphobic, xenophobic),misoginistic,misandrist, ableist, rascist,antisemitic,heavily nationalist attitude, thinking the world revolves only around you and that other people are just tools&objects, not cleaning after yourself, expecting other people to take care of things for/accompaning you as if they have an obligation, thinking violence settles things, refusing to pay people because "it's for exposure" and "they should do it for the experience/self fuffilment", loud music in public spaces(please use headphones), dismissing people's religious practice just because it isn't exactly how you would do it, pressing other people to live the life you want to but not living the life you want to live yourself, being needlessy pessimistic and cynical about the future(guilty), not being bewildered about earth and not wanting to learn or practice random things(who has time to be hateful when you see a beautiful leaf that has just sprouted?), lack of wanderlust.
Thinking about different languages in the terms of "useful" or "useless" according to the number of speakers they have.
Edit: What I mean specifically is not for someone to want or not to personally learn a language, but if the existance in itself of a language is more or less valuable according to how many people speak it (per example and as I explained below, believing that Occitan's existance is useless because there's already French to talk to Occitan people with, who already understand it). Yes, this happens.
