Welcome to the discussion of US Politics!
Rules:
- Post only links to articles, Title must fairly describe link contents. If your title differs from the site’s, it should only be to add context or be more descriptive. Do not post entire articles in the body or in the comments.
Links must be to the original source, not an aggregator like Google Amp, MSN, or Yahoo.
Example:
- Articles must be relevant to politics. Links must be to quality and original content. Articles should be worth reading. Clickbait, stub articles, and rehosted or stolen content are not allowed. Check your source for Reliability and Bias here.
- Be civil, No violations of TOS. It’s OK to say the subject of an article is behaving like a (pejorative, pejorative). It’s NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
- No memes, trolling, or low-effort comments. Reposts, misinformation, off-topic, trolling, or offensive. Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
- Vote based on comment quality, not agreement. This community aims to foster discussion; please reward people for putting effort into articulating their viewpoint, even if you disagree with it.
- No hate speech, slurs, celebrating death, advocating violence, or abusive language. This will result in a ban. Usernames containing racist, or inappropriate slurs will be banned without warning
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.
That's all the rules!

Fortunately for those of us who don't have a background in psychology: the folks who are experts tend to publish their findings!

So what do those parts do...
Anterior cingulate cortex: error detection, anticipation of tasks, attention, motivation, and modulation of emotional responses
Amygdala: formation and storage of memories associated with emotional events / emotional learning; fear conditioning.
...so, yeah conservatives are literally, physiologically hypersensitive to fear, and more prone to acting on emotion. WHO'DA THUNK?!?
I love a well sourced smackdown
Were you wanting to build some kind of argument or hypothesis with that segment, or did you just want to leave it to your reader to assume whatever it is you're thinking? Cuz the knee-jerk reaction your post evokes is that you're attempting to dismiss an entire study based on a disclaimer about brains being complicated... but such an attack to your critical thinking skills would ofc be a hasty and unfair conclusion considering you haven't contributed a single word of your own yet. So by all means, state your case.
Least chill comment I've seen on lemmy lol I thought I was on reddit for a second... It's a quote from the study you posted not everyone online is trying to debate you.
I'm a bit worked up. RL shit, not you - forgive my tone.
Meat of the last comment stands though: what's your point? I know it's a quote from the study, but that's how studies work: they provide supporting or detracting evidence to whatever it is they're evaluating. Even if that disclaimer wasn't there at all, it'd still be implied bc no one study proves or disproves anything, they just contribute to a broader pool of knowledge that eventually leans toward something being accepted as truth.
And right now that lean is toward conservatives being driven by fear and emotion.
Well I don't really have a point myself, the study has a point which is emphasizing that these neural processes measured aren't a direct representation of political opinions per se.
I guess my only relevant opinion aligns with what they are saying in better ways in the study, to which I would add that it gets dicey whenever people's thoughts/behaviors are reduced to something inherent about their biology. The authors of the study are putting in a good effort to avoid that reductive interpretation and explaining it very well. Biological indicators and many subsequent indicators are determined in complex ways by the conditions people are in and where they were born, etc.
LOL he's been going on the attack around here. This concept has broken his brain and he's just lost it.
I don't have a background in psychology either, but the prefix hyper- in medical contexts usually means something is abnormally and dangerously excessive in size, amount, etc. Yet from your quote there's no reason to conclude the on-average increased amydagla is necessarily abnormally increased. It isn't, it's just bigger, it's not automatically pathological.
'hyper' doesn't have a qualifier in scale; it's just an increase. Your arm muscles will hypertrophy after a single pushup... not by a significant amount, but by a higher than zero amount.
My understanding of the amygdala situation is that it follows basically the same model: conservatives aren't born with a massive amygdala that leaves them extra susceptible to fear and emotion; they do fear work-outs throughout their life by over-consuming shit like Fox News telling us the scary immigrants are here to out-breed us, or some preecher explaining how Jesus won't let you into heaven if he sees you masturbating.... over time they become the fear/emotional equivalent to a body builder; but when you start to look at the other parts of their brain, you might find they didn't just skip leg day; but that the very concept of leg day is something they find offensive and actively oppose.
