ok now is my chance. what is this (opens new tab) phenomenon?!

In the article, there's a link in the text right before they put that parenthetical. I'm guessing they're saying that the link interested them so they clicked it to read but opened it in a new tab so they could finish the current article first.

It seems to be hidden text in the page? Either way, it just shows up alongside links when you copy text from the article.

"researchers, including those spearheading the work, are cautious about overselling their results" Either it is correct; or it is not. Perhaps it is somewhat correct, but then it may not be fully correct, so it would contain wrong information. I write this here because science does not really work well when it is based on speculation. So this article is weird. It starts by speculating about something rather than anal…

> So their theory is incomplete as of yet. That's not good.

I hard disagree. Your comment to me reads as if a paper should either prove a new theory or disprove an existing theory.

However, publishing new results without a clear understanding of how it works is just as valid and this seems to be that. In Phsyics and Astronomy, new observations are often published without a theory of how it works. This is not a bad thing, that is part of the collaborative nature of science. The same holds true for papers suggesting a new theory, but lacking either observational or theoretical proof.

I guess this makes sense if you also consider the history of dog breeding. The best traits are always breed forward into future generations, those characteristics could be how athletic the dog is or how friendly the dog is.

You're talking about traits passed via DNA, which is nothing new ... this is quite different.

From the perspective of an individual breeder, they cannot know how much of a trait is from DNA or not. It may be more likely to be DNA-driven if you can prove that the trait is durable over many generations, in different environments. At least, that is my guess.

> they all have the same mother, grew up in the same house, etc. I’m pretty sure the first one didn’t have siblings, and the second only had one. Also their mother is not the same person after raising the first kid, or raising two. Parenting never have reproducible conditions.

I have twins (a boy and a girl) and you could tell they have a completely different temperament about two weeks after birth.

I’m a twin - admittedly boy/girl, so already with some fundamental differences - and we are very, very different people. Always have been. Different interests, different ways of seeing the world, different attitudes to competition, sports, social relationships etc.

Now I’ve got 2 boys, and even at fairly young ages they were very different. I’d say by 6 months old the basics of their personalities were visible, and they haven’t changed vastly as they’ve grown.

I'm insulting myself. I'm describing what is my family dynamic.

No, you're insulting boomers, and you just doubled down.

It was a self-deprecating joke which back-fired because nuance is lost on the internet. You got triggered, which is entirely human, but at this point, you're the one who is doubling down. Perhaps it's a good time to disconnect and enjoy some time with your family.

Adding "jk" after a casual prejudiced insult to a demographic doesn't undo the prejudiced insult.

Please tell me you’re joking.

He was, see his comment from 1h before you posted.

The twins I have known are the same. I would assume it has something to do with a desire to differentiate themselves from one another, but they always seemed far more dissimilar in personality and affect than my siblings.

OTOH could be siblings tend to be more similar as the smaller ones try to copy the older ones (my son would dress up as a ballerina to play with his sister when he was little, my smaller brother would acquiesce to play chess with me just to spend time together etc).

I have given up trying to explain child development, there's just too many variables.
