I understand how frustrating that must be. It sucks to have people tell you all of your life that you can't do certain things because of your intelligence and then have someone tell you it's "not real".

I think most people who say this (including the person you're replying to) are trying to reassure you, not dismiss you. The origins of IQ are arguably racist/classist and the science behind it is disputed by many. I was told all my life that i had an above average IQ, but i never understood why. I didn't feel smarter than my classmates and I did poorly in school. I later learned that I did well on the IQ test because of my economic background and the resources that I had available to me from a young age.

Intelligence is such a broad concept that we frankly don't fully understand yet. So the fact that we measure peoples intelligence and worth over a number is bullshit and dystopian. This is where the split in your experience comes from. You feel the effects of a low IQ because society values it too much. But most people know it's a metric that's used as a cudgel against others.

In other words, I very much believe that you are treated differently and have fewer opportunities as a result of your IQ, but that's an indictment of our society; not you. On top of it all, it sounds like you didn't have the support network that other people have. Verbal and physical abuse from the people who should be our guardians and champions (your father) will stomp the spirit out of anyone.

I know it might not be comforting, but I read your post and you didn't seem unintelligent to me. Sure, your sentence structure might be different than mine, but you seem like a thoughtful and connected person. What I'm missing, most likely, is the effort, time and energy that it may have taken you to write your original post, which i dont want to discount. But you're able to get your thoughts and feelings across just fine, at least in the form of writing.

Alright, enough with the pep-talk. Do you have any interests or things you like to spend time with? Video games? Animals? Exercise? Drawing? Writing? Makeup? Anime? Cooking? It doesn't matter if you think you're bad at them -- I'd recommend pursuing those interests. Sometimes volunteer work opens up opportunities that you haven't considered. It can also help you create that social safety net that I was talking about earlier.

I would try to get a job that gets you by (I know, easier said than done). Something like janitor work, fast food, retail, or hotel service. It doesn't have to be permanent, but just something to keep a cashflow while you give yourself time and room to grow. I'm not sure where your located, but I would check for non-profits or local orgs that offer assistance to folks.

Don't let our psychotic and unhealthy society dictate your worth. You are a human being who has thoughts and feelings. Your ability to hold a job or quuckly solve a problem is relatively superficial.

IQ only means something within a small subset of the establishment. It's a made up thing that is highly biased towards white European men. Yes, the system will hold you back if they determine you to have a low IQ, but for thousands of years people of all intelligences successfully lived in societies with others.

You have to give up the belief that the system is the sum total of reality. It's the reason you wonder if your life is over at 23 - because the system is narrow and myopic and only has a little space in it and everyone else is pushed out. But the system isn't even half of real life, and when you find the rest of life by giving up on the system you'll find your life is just beginning.

Carl Jung even said that life doesn't start until 40 - everything before that is just research.

IQ only measures how good you are at taking IQ tests. They recalibrate score every year to maintain the same distribution of scores within a year. (they change what each question is worth so every year 50% of tests get above 100, 40% of tests are between 85 and 100, 40% of tests are between 100 and 115, etc.)

The impact is that they have to make the tests harder every year. If you applied modern standards to 1920, the average score would be ~70.

What makes more sense to you, that 8/10 people today would be considered near-geniuses 100 years ago, or we got much better at taking IQ tests?

IQ does not define your destiny.

I don't know what my IQ is. Nor do I care what it is.

You sound smart enough to ask for advice. I don't think your IQ is as low. Let's go through some steps. You can type, read, write, use the Internet, figure out how to get on the fedi, realize you have an issue, and you asked for advice. That's more than 99% of people can do. My parents couldn't do what you did.

I was once told a story about an IT worker. They got called by a doctor about their mouse not working. The IT person tries to troubleshoot the issue with no luck. They go over to the Doctor's work station. The Doctor is trash talking them. The IT guy looks at the computer and realizes the issue instantly. The mouse is upside down. (This is a true story)

We are all smart in our own ways. We all have talents and gifts. What can you do well? And if you don't know that answer; ask your friends. Take inventory of yourself.

Speaking for myself as someone who was dismissive, my best contribution to the answers here is that it's reductionist to a seriously misleading extent. It seems like you have a couple of conditions contributing to your struggle, but it all gets reduced to "your number is too low." As others have alluded to, how much of that is your adhd? How much is from some condition you may have that hasn't been diagnosed because you have been unsupported throughout your life? I don't think anyone is denying that you have real neurological conditions that hinder you, they just doubt low IQ as being a meaningful description of what you're facing compared to something that gives a better causal explanation.
