    i just finished watching a video about those triplets that were separated at birth for a study that tried to answer this question. and experimental design when it comes to these questions is so important because it can easily cross into unethical territory

    I was trying to think of who he was reminding me of and this is the answer. His tone and rhythm of speaking is really close.

    One question I have is, in the segment about height, how exactly did you measure that 80% is genetic and 20% is environment? What does that even mean?

    Yes the environment can affect complex traits such as intelligence. However, in genetics there is something we call a phenotypic maximum, which refers to the upper limit of an organism's potential traits, determined by its genes

    I would definitely agree and say it's a combination of both contributors(genes/shared environment) However according to the behavioral laws of genetics, the effect of the genes>shared environment

    Black and white mentality, which is rarely true in the big scale and in general! It’s just a mix, and sometimes one thing is more effective than the other, but n the end i think nature is the base and the main cause of capabilities! I’m not expert, just my simple thoughts

    So people from a low IQ group are more likely (on average) to have a low IQ? But given environmental factors have the ability to increase it?

    0:20 Meh, I’m gonna say 60% Nature 40% Nurturer, so it is just enough that you can’t ignore your responsibility but not so much you can claim the true cause of the successful.

    What studies do you base that statement on? You clearly did not pay attention and don´t want to learn either.
