I googled but could not find source. I only found more memes based on this graph. Which isn't to say it's fake, could simply be in some research paper hidden away under a paywall. 15k sample is a very big study though.
The graph alone is highly problematic to make any argument though as it doesn't specify other critical axis such as age which would highly change the meaning of this graph. The older you are, T levels fall, but your IQ increases. So age alone can potentially explain the phenomenon we're seeing here.
My attempt to find the graph only resulted in many counter points, however.
https://pubmed.ncbi.nlm.nih.gov/9845018/ looked at only young men and women, so the age no longer becomes an issue. But among young men, higher T is advantageous. I can only read the abstract without paying. But does outline three conclusions there.
https://www.sciencedirect.com/science/article/abs/pii/030645309190018O this study on "normal" men and women, though not sure how they define normal, showed a negative relationship. But this once again doesn't define age in their study. Which continues with my previous point that simply older men will have lower T but higher IQ.
Is that the YouTube that couldn't grow a beard even though he was in his thirties so he had this hormone levels checked and his testosterone was through the roof?
Jep. Pretty sure that’s the one. Don’t think he ever got into what his specific ailment was though. And he hasn’t been all that active lately as far as I remember.
thats blatant discrimination against outliers, I vote the line be tweaked into a third order polynomial that fits the highest points to better fit the data.
Yeah I saw this and all I could think was "Mad! The guy is going to be mad about all of the stupid while also knowing he can't use his fists to make it (actually) better". A constant cycle of never having all of the solutions or a way to feel better.
How does this lead you there? IQ 100 is already the average by definition, so no matter how moronic people are as a whole this chart will look the same
Btw is this real? I thought there was no conclusive data on testosterone and inteligence being related. Most sources say that its the change which matters(meaning that if you start taking it) and not the baseline except in the extremes.
For about a month every day, he drank 500grams of protein powder, mixed with meth and cocaine - power lifted every day .... literally saw the face of God for a moment and could understand space and time ... then suffered a massive heart attack and died.
It's Add Health, so it's not even the R2 that's the problem but the fact it's probably got a ton of covariates not included in the model. Lots of contextual variables not in that set drive me nuts, although I'm not even sure if 5th wave exists or has testosterone data lol (haven't used it in years)
That's an easy wish! Last time I saw this plot people were saying that this kind of data doesn't even exist in the mentioned source (that and IQ is kind of bogus, but y'know)
