Reply to comment by NaturalisticDualism in The brain can rapidly detect and process fearful faces that are otherwise invisible to the eye. There appears to be a neural pathway for detection of fear, which operates automatically, outside of conscious awareness. by Wagamaga

Going to hard disagree for a second, but I'm not paying $35 to review the study so please provide more information on those studied.

Those with borderline personality disorder would be populations I would be interested in seeing the commonalities, as it's already well prove that micro expression mind reading is a prevalent trait in these subsets.

If this is similar to how we learn to stop hearing dialect sound patterns for instance, then there is a strong case for this being a trained perception, particularly in cases of childhood trauma before your brain start trimming out excess information.

Also, neurodivergent is a stupid term to begin with, who the heck is neurotypical? It's best measured in degrees, if that. Even the most average person across all metrics is exceptionally unique in their normative tendencies I'd posit.

Reply to comment by dustymoon1 in A study in the US has found, compared to unvaccinated people, protection from the risk of dying from COVID during the six-month omicron wave for folks who had two doses of an mRNA vaccine was 42% for 40- to 59-year-olds; 27% for 60- to 79-year-olds; and 46% for people 80 and older. by Wagamaga

These sources do point to an association between COVID-19 and increased risk of various autoimmune conditions, however, this is a far cry from conclusively saying “your immune system takes a hit with every covid infection as well.”

And it isn’t considered an “immune system virus”. That would imply it actively targets the immune system. There is evidence that it can infect certain immune cells like macrophages, but it is considered a respiratory system virus because that is the primary tissue it attacks (as opposed to an actual immune system virus like HIV, which specifically targets immune cells and spreads throughout the lymphatic system).

Not trying to be dismissive, but there is not enough research yet to fully characterize the effect on the immune system, or how long such effects might last, and claiming conclusively one way or the other is irresponsible.

No, this was specifically something they controlled for. They wanted to remove this effect from the study.

Hints that the unvaccinated were more likely to already in a poorer health. Sentence before the one you quoted: "We found substantially lower non-COVID natural mortality risk for vaccinated than for unvaccinated persons."

Which, if interpreted optimistically, might mean that people who skipped vaccinations had immunity system problems or were already too critically ill.

But it probably just means that the lifestyle choices of the unvaccinated people were generally much less healthy than the vaccinated people.

In the sentence after the one you quoted, they say they controlled for this effect: "After controlling for these selection effects [..]"

For reference:

> We used a novel outcome measure, CEMP, to study how vaccination affects COVID-19 mortality risk. This measure uses mortality from other natural causes to control for selection effects in who gets vaccinated. We found substantially lower non-COVID natural mortality risk for vaccinated than for unvaccinated persons. Thus, the vaccinated would likely face lower COVID-19 risk even if not vaccinated. After controlling for these selection effects, we found substantial vaccine protection against death [..]

Reply to comment by PsychologicalLuck343 in Investigators assessed the risk of dementia using changes in alcohol consumption in nearly four million people in Korea and found that after about 7 years, dementia was 21% less likely in mild drinkers and 17% less likely in moderate drinkers. by Wagamaga

I think you'd have to extrapolate based on this info and what you know about yourself/the 20%.

I'd imagine it's all tared down a bit for you, but somewhat proportional. What is considered mild/moderate drinking for you - and go from there.

Reply to comment by tsowmaymay in Cultivating a sense of perspective about pet loss can lead to post-traumatic growth after their death by chrisdh79

My therapist told me to kinda treat my mind like it’s someone who I’m friends with coming to me asking for help on anxiety. And try to focus on perspective - so many people have it much worse than you. You’ve got a roof over your head. You’ve got more than enough time to fix how you feel. Take a deep breath. Things are going to be ok.

Why is the term "invisible" used so casually and without qualification in this study? My understanding is that it means "not consciously perceptible", which is a completely differemt thing that "invisible", in normal parlance.

The part in the title about being outside of consious awareness is not really accurate to the story. This is happening before the cortex. There's tons of other stuff happening in the cortex that is outside of conscious awareness. It's not that this is unconscious thats interesting, most things are unconscious, its that it happens even before the cortex.

Reply to Social mobility refers to movement of individuals from one socio-economic strata to another. Social mobility is largely driven by personal motivation, education, skills and migration. But an analysis of historical data tells us that social mobility is primarily caused by changes in political rule. by rustoo

How would you ethically test for the effectiveness of a vaccine in blocking transmission?
