Checks out, really.
Wouldn’t it depend if you’re listening to audio book?
Well guess I’m fucked. We have zero public transportation in my town surrounding my entire neighborhood is all highways. And only way to get anywhere is by driving
Causality… Stupid people drive more.
It’s easier to become a paid driver than a paid thinker.
IQ is not an objective measure of intelligence. Nothing can be because intelligence is colloquial and subjective. If I told you that I had an instrument that could objectively rank all humanity by beauty, smart people would see the problem immediately.
IQ depends on their being one kind of underlying intelligence. No such thing as ‘book smarts’ or ‘street smarts’. Emotional intelligence is also fake. Just logical problem solving and spacial recognition.
IQ is racist. IQ consistently shows that black Americans have lower IQ than other groups. White supremacists love this fact because they view it as scientific evidence that black people are inferior.
“Race” is biologically incoherent, but “black American” is the most incoherent of all. Barack Obama is a famous black American. But his mama is a white lady named Durham and her people are British. In the Jim Crow era South, 1/16 black ancestry made you 100% legally black. That’s one great-grandparent. White and black Americans have been cross pollinating for 400years. Sometimes even consensually.
“Black American” is not a coherent biological category. Therefore, when IQ tests mark differences between these groups, it can ONLY be measuring social difference because their is no biological explanation.
IQ is not an objective measure of intelligence and any study based on it is faulty.
IQ is a reasonably effective metric of certain kinds of intelligence. It doesn’t measure all intelligence and has some caveats, but it still highly correlates with certain abilities of one’s brain. IQ decreasing over time in the same subject is a cause for alarm.
And you absolutely can objectively measure certain types of beauty. If you managed to rank all of humanity by facial symmetry, I’d think you were a bit weird, but I wouldn’t say that you were wrong.
The original article wasn’t talking about IQ at all - Reader’s Digest was oversimplifying the research.
Cognitive tests included prospective memory (baseline only: n = 171,585), visual-spatial memory (round 1: n = 483,832; round 2: n = 482,762), fluid intelligence (n = 165,492), and short-term numeric memory (n = 50,370).
hence the term “car brained”
I don’t think this is new information at all. It’s long been known that say rats put in a stimulating environment have more developed brains, more grey matter, and a higher intellect, than ones kept in a boring enclosure.
What is in question, is how much of that drop in mental ability is from particulate matter and such, which is something it does do, and how much from just not thinking?
The study found similar results with participants who partook in several hours similarly sedentary activity, like television watching.
Does it apply to motorcycles?
I think the issue is insufficient challenges for your brain to deal with on an intellectual level. If you don’t use it, you lose it kind of thing. Which sedentary activity you’re doing doesn’t itself really matter.
Ah, so driving in SEA is safe, got it.
“driving”, they’re all just standing around
Well yeah, experiencing >1000 motorcycles and bicycles all blocked in and boiling in the Hanoi heat because of like 10 cars and a van will solidify ones unending loathing of cars, but usually things aren’t so bad and you get the fun of weaving and finding the ever-changing paths between bikes, pedestrians, cars, construction equipment, and potholes, whereas cars are just forced to go and stop when somethings in the way.
I think that’s more of a challenge to your patience than your intellectual processes.
Getting stuck in traffic in a car or cruising on a freeway is an exercise in patience, tracking which of the hundreds of bikes around you you have to pay close attention to while operating a motorbike is mentally exhausting.
Yes, but what to do in any given situation is not exactly a mental challenge. You don’t take an undefined amount of time to think through all the possibilities & outcomes - you have to make split second decisions that are mostly instinctual. This is far from being an intellectual process.
I doubt it, riding a bike is much more involved
Oh, that famous Journal called Reader’s Digest.
Here’s the original article: https://doi.org/10.1093/aje/kwx273
Abstract:
We investigated the cross-sectional and prospective associations between different sedentary behaviors and cognitive function in a large sample of adults with data stored in the UK Biobank. Baseline data were available for 502,643 participants (2006–2010, United Kingdom). Cognitive tests included prospective memory (baseline only: n = 171,585), visual-spatial memory (round 1: n = 483,832; round 2: n = 482,762), fluid intelligence (n = 165,492), and short-term numeric memory (n = 50,370). After a mean period of 5.3 years, participants (numbering from 12,091 to 114,373, depending on the test) also provided follow-up cognitive data. Sedentary behaviors (television viewing, driving, and nonoccupational computer-use time) were measured at baseline. At baseline, both television viewing and driving time were inversely associated with cognitive function across all outcomes (e.g., for each additional hour spent watching television, the total number of correct answers in the fluid intelligence test was 0.15 (99% confidence interval: 0.14, 0.16) lower. Computer-use time was positively associated with cognitive function across all outcomes. Both television viewing and driving time at baseline were positively associated with the odds of having cognitive decline at follow-up across most outcomes. Conversely, computer-use time at baseline was inversely associated with the odds of having cognitive decline at follow-up across most outcomes. This study supports health policies designed to reduce television viewing and driving in adults.
Good news is that it’s not hereditary. Protect your brains kids. This is your brain on when driving 🍳
On the flip side, making mental maps, like professional drivers do, seems to protect against Alzheimer’s
Probably not worth the pain, but it’s sort of opposite to this.
