The greater your weight, the lower your IQ, say scientists
- badrabbit 8y agoCorrelation != Causation These types of studies are excellent for drawing a hypothesis not a conclusion like "obesetiy makes you dumber" My theory -- people eat more and excercise less due to some sort of stress. Stress that prevents engagement in activities that promote cognitive capacity or possibly even cause neural damage. But again,only guesses. The less we have publications containing only correlative conclusions,the better(imho)
- SamReidHughes 8y agoMaybe... but my mental sharpness increased as soon as I started exercising and watching my diet. I was stress free before and after 45 lbs of weight loss. Maybe it has more to do with eating meat, fewer carbs, or the exercise, rather than weight. My impression of mental sharpness is in terms of programming, and also how many typos I make, and how much energy I have to shape sentences when posting comments. I wouldn guess the main reason is that I'm sleeping better, breathing properly at night. Edit: I'd say sleep is definitely one bit of causation behind the correlation right there, but I don't know how big it is.
- acct1771 8y agoYes. My non-professional opinion is that oxygenation is the key.
- ironic_ali 8y agoThis study is married with bias, the French have had it in for the English since Waterloo. J/k
- andrewmcwatters 8y agoYeah, I'm gonna flag this. Mind you, my BMI is in the underweight range, but articles like this are total bullshit. They read with particular intent, and it's important to understand what the intention is of publishing garbage like this. It's on par with studies about how scientists tend to not be religious. Or how black people tend to be poor. Or how women tend to be less ambitious than men. If you want to call fat people stupid, just fucking do it. But this is tabloid-level trash that doesn't belong on Hacker News.
- throw-far-away 8y agoThank you. Junk pseudo-science "news" doesn't belong here. Waits for articles about Pony development and use in production
