Reply to New study (n = 15,764) shows repeated concussions are linked to worse brain function in later life by unswsydney

Hi r/science, jumping on to share this research led by UNSW PhD Candidate, Dr Matthew Lennon MD in collaboration with researchers from the University of Oxford and the University of Exeter.

The team found that people who experienced three or more concussions had worse cognitive function, significantly worse concentration and a reduced ability to complete complex tasks.

This is the largest study to explore the cognitive effects of concussion, or traumatic brain injury to date.

Here’s a link to the full study in the Journal of Neurotrauma, if you’d like to take a look: https://www.liebertpub.com/doi/10.1089/neu.2022.0360

Even the small countries in Europe think they’re culturally superior. It’ll never go away. It’s deeply ingrained into our thoughts (like elsewhere, Japan for example). Even more left-wing people in Europe think they’re culturally superior, they just go a different way about it.

Also, we will dig deep into our history to dredge up something to justify hatred of our neighbours, even if it was 200 or 600 years ago. That’s just the way Europe is

You might not want to include narcissism and impulsivity. A narcissist is very worried by how they look and seem to others, psychopaths aren't worried at all. Impulsivity is more related to sociopathy or antisocial personality disorder.

tl:dr the data availability statement? This is good practice for data and code sharing tbh.

"Final demand data for the 27 EU member countries, as well as global MRIO tables and environmental extensions were retrieved from the EXIOBASE v.3.8.1 database (https://zenodo.org/record/4588235)14. Coefficients for biodiversity loss from land use were collected from ref. 12. Data for calculating regional average GDPpc were retrieved from the World Development Indicators DataBank (https://databank.worldbank.org/source/world-development-indicators)63, the World Economic Outlook (October 2022) (https://www.imf.org/external/datamapper/datasets/WEO)25 and the United Nations World Population Prospects 2022 (https://population.un.org/wpp/)64. For creating maps, shapefiles from Natural Earth (https://www.naturalearthdata.com/)65 and the Eurostat R package66 were used. Data for recreating the results and figures are available in the Supplementary Code. The main results are collected in the Supplementary Data."

the metaphor is valid for epidemiology studies. at the core you're just tallying the chances of an objectively observable binary outcome in a series of predetermined groups

I'm not sure where your experiment of rolling infinitesimally loaded dice in a sealed black box is coming from but it's so completely absurd and disconnected from the practical and theoretical considerations associated with epidemiology that I needn't comment on it

>always is correct

Now you are just being disingenuous. You and I both know that this wasn't your first use of the word "always," nor was it the one I was referring to.

>my very first answer could have specified "always in epidemiology studies", but it was evident from context;

Really? Your very first answer include the following example:

>It's like if you're trying to check if two dice are loaded, but there's one die you can roll every few seconds and another you can roll only once every hour

The reality is that, unless you are suggesting that rolling dice is an epidemiology study, then the context clearly wasn't limiting your claim to epidemiology studies. At the very least, the context was applying your statement to dice rolls as well.

EDIT: Funny that you don't even attempt to address my claim (e.g., at the very least, the context of your example was meant to apply to epidemiology studies and dice rolls). Instead, you just make a reply that doesn't attempt to address this point and then block me.

> of course there are other factors involved, but statistical power is always hugely dependent on the raw numbers

always is correct

my very first answer could have specified "always in epidemiology studies", but it was evident from context; unless you've forgotten what this discussion is about (which very much seems to be the case, at this point you just want to convince yourself that you are right to doubt the faithfulness of the original article and whoever defends it)

Acetone isn’t good for you and a bunch of shop’s problems still use it.

>You're over-interpreting

Nope. You said "always." I called you out on that as being an over generalization that didn't hold water when applied to all specific instances. You response was to make personal attacks about how I don't understand statistics.

>...and have built a straw man that I won't bother taking down

You didn't say "always"? You didn't push back and resort to personal attacks when I called you out on this being an over generalization?

Or are you saying that you agree that it was a over generalization, but you still personally attacked me for pointing it out?

I've already given answers to these arguments. You're over-interpreting what I've said and have built a straw man that I won't bother taking down

if you want to believe you know, do just that

People just think evil people are psychopaths so if someone's evil they must be a psychopath and if they are a psychopath they must be evil. There are plenty of nmgood psychopaths out there. The media just loves a villain. Also a lot of research into the subject is only done in prisons on CRIMINALS. It is going to skew the data.

I think it's interesting that the US has a roughly 20% false conviction rate, but only 15% of those tested had a score lower than 10. That means that the entirety of those with low scores could be innocent.

Look in the mirror.

You're either pretending to have a job collecting and analyzing data or you are pretending to believe that you can easily reach statistically relevant results for any question of interest, as long as something has happened ~1,000 times, even if it is impossible to observe or measure these ~1,000 events.

Not only that, you claim that this is an "elementary statistical principle." Maybe you should pump the breaks on accusing others of not being honest here.
