/sci/ - Science & Math

Hope this is a /sci/ related question?
Took an iq test it's mid 80s.
Is it scientifically possible to increase IQ?
There seems to be debates between scientists on this topic.
I see the test as random patterns but what does that mean in real life?
Can I never get a PhD that I wanted?
Can I never understand higher and scarily advanced math? Or does it mean I just have to work harder than someone with a high iq.
If the brain can physically change while learning something for example the taxi driver experiment where specific parts of their brains were bigger because they had to memorize whole cities, and once they stopped being a driver that area shrank.
IQ is a good predictor of financial success and academic success.
But does it means to just give up and rot?
Will I never be able to understand what Stephen Hawking understood if I pursue a path that he was on hypothetically?
Would I be able to make contributions to the academic world, discover, or invent something?
If you're an expert on a topic you should be able to break it down well enough to explain it to a grade schooler, although it will of course take longer.
But that's obvious cope right.

Can you increase IQ scientifically?
Is my learning forever stunted?
Is it over?
