I read the abstract of the referenced article, this entire image is Conservative nonsense. The study did not find that liberals had an "atrophied" amygdala. It showed that conservatives have an enlarged right amygdala, due to their overpreparedness for a fear response.Meanwhile, the study found that liberal had a larger anterior cingulate cortex, which is an area of the brain commonly associated with empathy and other higher-order processes like decision-making.
The study provides support for conservatives being scared piss babies who are overly terrified of the world, whereas liberals are empathetic and make better decisions. The fact that this idiot made the entirely wrong conclusion is almost as incredible as it is sad.
That may be because OP had an agenda to push whatever the means, or simply is conservative.
BTW, anybody remembers some other studies similar to this, used to show how certain demographics were basically worse in a biological/genetic sense? Something around 1920-'30..
Phrenology was the pseudoscience that was used to enforce the ideology that white people were superior by looking at the inside of a skull and measuring certain areas and using those measurements to justify racism
Look, psychology in the early 20th century was an absolute mess. There's a reason we now have stuff like ethics boards, and strict constraints on the kind of studies that can be run.
Yep, there are several studies researching this in various ways. An important thing to point out is that those two portions of the brains are inversely correlated without affecting other portions of the brain like the frontal cortex. So a person can be a good doctor or scientist and also be conservative. So conservatives have high fear responses to people who are different and lack empathy while left leaning people have less fear and increased empathy. Studies also show that brains develop to have an oversized amygdala when they have physical or emotional abuse as growing up or if they have severe lack of resources.
It's like reading the Muller report, or for that matter, the constitution. Pro-Tip: it helps if you don't bother to read it at all. That way you can pretend it says whatever you want it to say! Oh yeah, the Bible too - "the worker deserves their wages; don't be a Karen; nor a pedophile either; be not afraid and instead be kind to everyone you meet, etc."
yeah, that's very standard. lotta universities have requirements on undergrads participating in studies. that's why you often see them as the subjects.
It's certainly fair to criticize, and it would be interesting to see if the study's findings hold true for a broader population, but finding test subjects is tough. you take what you can get.
Here's some neuroscience knowledge. If a part of the brain is overstimulated and requires too many resources, it actually gets expanded to the detriment of other parts of the brain. The inverse is also true, if a part isn't used other parts become more dominant. As seen when the brains of blind and deaf people were studied, it was found that the brain actually rewired itself to improve the still working parts.
It's simply your brain being efficient with it's resources. That means the amygdala of conservatives is so overstimulated that it leeches resources away from the rest of the brain.
They can also often be some of the kindest people as well, at least individually even if not from a societal standpoint. It's strange to think about, I know!
They just think different - accepting argument by authority more readily than using skeptical thought to personally analyze all input. And in that sense, they share a lot more in common with liberals than the latter group is comfortable admitting... Most thinkers are liberals but the converse is not true.
Also, everything changes - this Alt Right (or whatever term has replaced it now) is nothing like the Tea Party brand of fiscal and social conservatism that it replaced, which itself was very different than the old-school conservatism, like George W. Bush was a freaking progressive, who wanted to fund education and feed the homeless (and despite the ineptness of their implementation, he did end up doing both!) (And on and on it goes, further back, e.g. Lincoln freed the slaves - what will Republicans be ten years from now, I wonder? At some point, the two sides will switch again, it's the nature of the game.)
It's so easy to simply blame the other side for being inept, but even if true, it does not absolve us from not accomplishing anything ourselves. e.g. abortion is now up to each state to decide, so an excellent time to pass laws protecting it in each state... before conservatives find a way to do the opposite?
Yes. That's the whole reason for the tribalism. It's a survival mechanism that helped our ancestors. But it's wildly out of place in our modern world. And sadly many people's brains are on the legacy firmware.
Who there, commie! There's just one God and his only job is to kiss my forehead and pat my hair and tell me I'm a good boy and everything is His plan and it's all going to be safe and okay and I'll get to live with him in Cozytown before everything is destroyed.
Their recent ancestors also migrated there, and look how they treated those who were already there before them. Now, every time they look in the mirror there is a guilt they will not fully acknowledge, but it's there, and deep down they're afraid they'll end up faring like the natives, that they'll end up getting treated the way they have treated others.
That they'll get treated the way they know deep down that they deserve.
No coincidence that those most loudly and vulgarly opposed to immigration are concentrated in the racist, confederacy-sympathizin' pro-slavery south.
It's so easy for charlatans to successfully pop-up in that environment and whip the people into a frenzy, feeding them more ignorance and fear every day. You get the evangelical preachers and the republican politicians, and the line is blurry between the two.
