“...researchers can seek both environmental and genetic contributionsto successful cognitive...”
Dangerous turf.
This presumes that some people start out with more smarts ... and so end up with more smarts. Right?

Yes...I was also struck by that first sentence. She treated it as it was settled science (which it is)...only the ostriches tried to deny it.

FTA: On the other hand, whether this intelligence changes over time, they found, is very reliant on the environment.
Well, duh!

Actually, the surprise here was how much the environment plays into maintaining (or losing) cognition over time. The intelligence you’re born with is mainly determined by genes (as the article notes, mainly from excellent studies looking at identical twins reared apart), so the findings here were perhaps unexpected by some researchers in this field.

I’m guessing part of the environmental would include how much ‘exercise’ an individual gives their brain . It’s like a muscle use it or lose it.

You are a good guesser: the data on what you describe tends to support your supposition.

My grandmother’s common sense could have predicted this. If you have the ability to understand and learn math, but you never use it throughout your life, you won’t remember how to do algebraic equations when you are 90.
Those famous “Twins Studies” from the University of Minnesota were conducted by Thomas Bouchard, formerly my neighbor in Berkeley when he and my husband were both students at UC. I used to babysit his daughter, Elizabeth, daily to earn extra money. I wonder how many IQ points I shaved off of that child by being exposed to me every day! LOL

Darned if he wasn’t right every time.

Ha! I'm sure you added...you're Freeper, right??
And I have been following Bouchard's work since the '80s when I saw the first reports. Wow...I am impressed.
And, you survived Buhzerkley!

Half of our chromosomes come from mom, half from dad.
*On average* one quarter come from each grandparent, but obviously there is no integer solution to one quarter of 46, so the concentration of genetic origin begins with the grandparental generation, and it turns into something analogous to the old "war" card game -- an early advantage means eventual victory. Here's some arbitrarily and randomly assigned values, showing the pathway to the 46 of the current hypothetical person (but entirely possible, and given the 2^23 squared possibilities in each generation, this is bound to have happened at least once by now, to someone, somewhere):

I started from 46 and worked back, but if we wanted to maximize the number of genetic sources from the 4ggrand generation (46 of 'em, of the 64 on the tree), we need only put zeroes in 18 of them at random, then carry the totals additively downward. Probably would be a lot easier than the pain in the neck I just went through with that. Hope I didn't miss any typos. And of course, the other way to do that is to do the actual family tree and see if there are any duplicate ancestors. :')

A person's intelligence is mostly inherited, it's in their genes, but whether a person can expect to be a clever grandma or grandpa relies on both genes and environment.

I've just bought three pairs of genes at Target. You mean they'll help me remember? What?
