    Yes general intelligence is related to genes. Two important caveats:

    1. Don’t forget the environment. See the Flynn effect, according to which measures of general intelligence have risen over time, showing the effect of the environment. This is just like height. The Dutch were once amongst the shortest people in Europe, and now they’re amongst the tallest. It’s true that they are tall now, in part, because of their genes, but, since they used to be short, obviously there’s much more to height than just genes. The best genes won’t help an unwatered seed sprout. Someone with low intelligence now might have the genes of a genius, if only they had received an education.

    2. Racists are still wrong. There is an overwhelming consensus that there is no genetic basis for race. There is no gene or set of genes or distribution of genes that all and only members of a race have. In fact, there is more genetic variation within races than between races!

    My personal take is that intelligence is much like muscular strength. Genetics probably play a role but the more important factor is how you use and train your cognitive strength. A cognitively sedentary person will almost always be less intelligent than a cognitively active person, I doubt genetics play a large role unless we’re talking about people who put similar levels of effort into their development and upkeep.

    Yes. We have plenty of studies indicating that IQ deviation (for lack of a better measurement) is heritable.

    This is even observable casually - plenty of people gossip about $LOCAL_FAMILY having a history of Darwin award attempts, or how $OTHER_FAMILY is stuffed with straight-A engineering students.

    However, it’s only a component, not the whole story. Intelligence can be built up like muscle - Joe Average who trains will beat out Sally Smartypants who doesn’t.

    I’m intoxicated so fuck me.

    Yes. There is a genetic link to IQ.

    IQ doesn’t test all kinds of intelligence though.

    Iirc, you can alter your IQ, just as you can expand your other intelligence areas acumen.

    In developing a specific intelligence acument (verbal, logic, interpersonal, nature, et al), you increase the odds that your offspring develop similar acumen

    Iirc this finding is significantly leaning towards nurture, and not nature (,genetic)

    Anyways cheers goodnight someone smarter than me please correct and source if you’re diligent and stuff

    No I don’t think so. Its definitely more of an enviromental upbringinf and personality predisposition thing. Some people just simply aren’t heavy thinkers or curious about anything. They live their life one day at a time in the moment without really contemplating anything. Its not genetic inheritances, its just how they choose to be/are.
