  • N=15 is a normal size on FMRI studies. It is about the smallest size you can have and still make your significance cut offs while still detecting decently small effects. The time and cost is so much higher than other studies. Some of the bigger FMRI studies start to reach 30-40 ppl. Getting into clinical trial sizes of subjects is unheard of.

    The other thing with FMRI studies that most everyone doesn’t understand is that they aren’t actually looking at activity. They are looking at the BOLD response (blood oxygen level dependance) and that is then correlated to activity. Meaning You can only see blood oxygen uptake. You are not seeing neuron firing, just the metabolic side effect of oxygen use after increased neuron use. This is why you will never be able to see something like a “thought process”. You can only track structures/locations used.

    At the same time we know that no two brains are wired the same even for the smallest of tasks, but they will “structure” their wiring the same. There have been literally hundreds of studies that indirectly see that. Soeach other. Plot out cultural differences versus individual differences would be basically two variance plots on top of eachother.


  • Participants 120 We analyzed fMRI data from N = 15 (2 male, 13 female) participants aged between 22 and 35 121 years (mean: 25.5) who took part in a previously published fMRI study about color vision 122 (Bannert & Bartels, 2018). The participants were the subset from the prior study for whom the 123 cortical retinotopic representations of the visual field were measured along both the polar and 124 the eccentricity axis of the visual field. All participants had normal or corrected-to-normal visual 125 acuity and were tested for normal color vision using Ishihara color plates (Ishihara, 2011). Each 126 participant gave written informed consent before the first study session. The experiment was 127 approved by the local ethics committee of the Tübingen University Hospital.

    Ignore the numbers 120-127, those are line numbers.

    Doesn’t say. To be fair, you normally aren’t allowed to collect biographical data or any additional identifying data without a specific purpose tied directly to your research question. If they wanted to answer your question they would have to redo the study under a different IRB application. Interesting question, but I would guess you wouldn’t see a difference in an fmri. The voxel sizes for functional are normally 2mm while what you are eluding to is the difference of a few thousand neurons wired a little differently. That difference would be extremely difficult to detect with 2mm voxels. Even at 1mm it would be difficult. When it comes to brain structures there really aren’t significant different between races or cultures more than the variance that already exists between people.


  • Every person eating out of a dumpster is a failure of the system. How has our economy not incentivized creating a method yet to maximize the wealth we could be extracting from these people?? We could slap a simple coin op slot onto those dumpsters and operate them like an unregulated vending machine. We could come up with a subscription model to allow monthly access to eating out of them. We could even figure out some form of alternative decentralized money system to get around FTC regulations and pesky labor laws on how we pay and receive the money from these homeless people. Capitalism is the greatest economic system ever created and we need to find a place in it for the homeless to contribute their fair share to the shareholders.


  • I love a good impossible burger over a normal burger for the big reason of how I feel after. Eating a normal burger as I am getting older means that I feel full in a gross way after, like I can feel the fat from the burger slowing me down, and I feel tired both physically and mentally and I sometimes feel borderline sick for an hour or so after. But with the impossible burgers I can just feel full in a healthy way. I love it. I will admit to also getting it with bacon though for that extra flavor.

    I an pretty anti factory farm and love the idea of cutting out at least burgers from their industry. I also enjoy their sausages. Highly recommend them if you have not tried them. I try to cut out bulk meat eating for the environment and keep it to occasional, smaller portions, and even then it is normally chicken. Impossible meat helps scratch that itch if I want some meat but don’t want to commit to blowing my personal weekly allotment of red meat.


  • There are some great lists here. I am just going to add- put a whole home water filter on the cold water line of the kitchen sink. It has changed my life. I only need to replace the filter at most once a year, it is on the cold water line that is almost as good a fridge water dispenser would be, but with more pressure. And now when I make pasta, fill up the coffee pot, make tea, or whatever other random kitchen thing that needed water, it is filtered water. Not to mention the clean taste.

    Actually, there was a Supreme Court case about this. If you just sit there and say nothing after they give you your Miranda rights, they can make assumptions about things or simply continue for as long as they want. The case concluded with- you must declare that you understand your rights in some way and that you are invoking that right.

    I did human intelligence. It was literally my job to interact with the people. And we did. And not just to hear what they say to our face, but to get sources and find out what people say behind our backs too. I can, with high confidence, say that close to 90% of the population wanted the taliban gone. It was the other 10% that were the issue. And they were the very loud minority that news stations loved to interview just to claim “accurately showing both sides”.

    Under taliban rule Afghanistan was economically devastated and the second poorest country in the world. They had one of the lowest literacy rates in the world. And they had no healthcare system to speak of other than what was gifted to them from Iran or Pakistan depending of what half of the country you were in. No to mention their lack of infrastructure with the not even completed one highway ring around the country.

    That all changed under ISAF and the people noticed. And now their past is about to become their future.

    Lol. I did two tours over there. The people loved us. They loved the government. They loved the schools for women. The problem is culturally, they didn’t see a need to fight for it because of apathy. They figured “ISAF was always going to be here, so why need to fight for ourselves? And is ISAF isn’t here anymore, then we can’t support our selves, so why try?” As far as the schools go, they are voluntary. There are no truancy laws. They don’t even take attendance at most of the schools. It was completely up to the family if they wanted to send their boys OR their girls. Under pre-ISAF taliban the literacy rate was about 15% and at the time of withdrawal it was almost 40%. The people wanted to go to school, the taliban just didn’t let most of them or the schools that they did keep open were so severely limited in what they could teach.

    The biggest red flag of this post, to me, is the use of the word Afghani. Any time someone says it with an ‘i’ at the end, you know they don’t know what they are talking about. Afghani is a currency, Afghan is a person.



  • While I understand the resentment of saying an institution is a person, and I agree- they still have constitutional rights. To say that private institutions don’t have a right to free speech is the same as saying that the government is allowed to dictate what companies can and can’t say. Authoritarians would love for you to push that idea.

    Under your same thinking (Harvard isn’t a person and has no right to a first amendment? OK): Then Harvard resisting against the trump administration is illegal and we find it treasonous to be funneling in possible spies from adversarial countries under the guise of education. We need to lock up anyine who works at any higher ed institution unless they can swear loyalty to America (trump) because they might be complicit in this spy ring. And don’t forget, the universities can be searched at any time for evidence and assumed guilty without trial because they aren’t a person and don’t have constitutional rights! Can we charge the university entity with state laws or federal laws? Both! They don’t have rights to protect against double jeopardy!

    You either lost money, or you lost time. If you are implying that you lost nothing because you didn’t cash out and therefore can wait for a rebound, then you are going to lose the time you have to wait for the rebound. In economics that is also called an opportunity cost. You have now lost the opportunity to invest that money into something profitable because you have now tied it up in something that is unprofitable. You still lost. You are just too dumb to realize it with this mentality.

    Worst case is when people with this mentality ride a stock to the bottom insisting it will just take more time to come back, and it doesn’t. Then forcing the person to lose both the money and the time.


  • I miss HEB. family owned and private. Thus why they get away with treating their employees so well, paying them well, and supporting their communities all while also being the largest private employer in the state of Texas. That company is a great example of how a company can both grow to a large size and not be evil. If they ever go public you know all of its charm will instantly get cut in the name of shareholder value.




  • This article is written with some wild speculations by both the author of the article and the source they are quoting. When cell phones are cracked for evidence they have to use write blockers when they copy the phone. They do the analysis on the copy. The original is then re-copied in court to show what was found. This way the original is never tampered with and made inadmissible, and whatever analysis bullshit you did isn’t mixed in with your court room copy. What this also means is that your AI can hallucinate all it wants and make up any evidence you can imagine all day long, but when you get into the court room and have to then point to where the conclusions came from and you can’t-you will be standing there with a dick on your forehead and with a case being tossed out.


  • While I have progressive ideas and believe the Republicans rule with malace, I also strongly believe the democrats rule with incompetence.

    I would love to run for president on the party of burn down the two party system and restart from there. Make politics boring again and not some partisan winner take all spectacle. We keep pushing to out ‘wing’ the ‘wing’ and it is driving us to some bad extremes.

    So yes, I will vote straight ticket Democrat for 99% of the time, but I am also disgusted by the fact anyone is even allowed to do that and people have little party letters by their name. If you didn’t research your candidate to at least know their name, then you shouldn’t be voting for them.

    It is mind-blowing to me that some things are not seen as human rights and are instead seen as political posturing. In Texas we had barbed wire intentionally strung up in the Rio Grande river with the intention to drownd people and it took multiple rounds of court cases to make them take it out. Somehow killing people is acceptable rather than booking, ticketing, and sending back. Politics have now taken a place above literal lives. At the same time, when I express this I have democrats immediately agreeing and adding “just let them in!” Or “just let them stay and we will figure it out” and that is where I stop them and ask, is that what I said? No. Simply that human life is worth more than politics. Again, stringing up barbed wire in a river to intentionally drown people it true malice. But saying let them all in and figure it out later is naive at best, and incompetence at its worst.


  • I saw patients this past week. Like I do every week. That is my one bullet point. I still need 4 more bullet points??? This is ridiculous. I’m doing my job, that I have been asked to do. He doesn’t know what my job is. The AI they are going to feed my answer through doesn’t know what my job is. The people who do know what my job is know that I am doing it just fine. We already have an evaluation system that I have to sign every 6 months and submit bullet points with.

    My supervisor, and their supervisors, are now going to have meetings about us responding. Then we are going to be told in meetings about how to respond. Then I spend some arbitrary amount of time responding. Do you have any idea how much combined time across the entire government is being waisted on this? This is literally millions of dollars in total time waisted just for the whims of a mad man. This is a prime example of wasting tax dollars.
