The power calculation indicates a 20% chance of getting useful information. My quasi-experiment has <70% chance of being right, and I preserve a general skepticism about any experiment, even one as well done as the medical student one seems to be, and give that one a <80% chance of being right; so let’s call it 70% the effect exists, or 30% it doesn’t exist (which is the case in which I save money by dropping fish oil for 10 years).


Do you sometimes feel like you are only half-there in your daily conversations because you lack concentration, or mental focus? With Cognizance you will no longer be wondering if the people conversing with you realize your lack of mental focus as you interact. This supplement helps by improving mental clarity and focus1, boosting intelligence levels, memory function, and increasing your level of concentration and alertness. As an added bonus, Cognizance can provide you with an increased level of energy and improved mood. COGNIZANCE BENEFITS: - Improves mood - Boosts memory function - Raises intelligence levels - Increases physical energy - Improves mental clarity - Boosts ability to focus - Improves concentration - Increases level of alertness The proprietary ingredients in Cognizance improve the functioning of the mind and body in several ways. One ingredient, dimethylaminoethanol is responsible for improving mood, boosting the function of the memory, raising intelligence levels, and increasing physical energy. Another, L-pyroglutamic acid, works to improve mental focus and concentration. These ingredients, combined with the others in Cognizance allow it to offer these benefits and more.
The brain of animals features in French cuisine, in dishes such as cervelle de veau and tête de veau. A dish called maghaz is a popular Muslim cuisine in Pakistan, Bangladesh, parts of India, and diaspora countries. In Turkish cuisine brain can be fried, baked, or consumed as a salad. In Chinese cuisine, brain is a delicacy in Chongqing or Sichuan cuisine, and it is often cooked in spicy hot pot or barbecued. In the southern part of China, pig brain is used for "Tianma Zhunao Tang". In South India goat brain curry or fry is a delicacy.
There are a variety of substances to get magnesium from. Considerable enthusiasm for the new compound magnesium l-threonate was stirred by 2 small animal rat studies finding that magnesium l-threonate was able to increase magnesium levels in the brain and improve learning/memory tasks. (There are no published human trials as of October 2015, and evidence of publication bias, which I take as evidence against there being large effects in humans.) Animal studies mean very little, of course (see the appendix), but I thought it’d be interesting to try using l-threonate, so I bought the $30 Life Extension Neuro-Mag Magnesium L-Threonate with Calcium and Vitamin D3 (205g), which according to the LEF product page works out to ~60g of Magtein™ magnesium L-threonate and ~4.31g elemental magnesium inasmuch as LEF claims 2000mg of threonate powder provides 144mg elemental magnesium or a 14:1 ratio. (I don’t need the calcium or vitamin D3, but this was the only magnesium l-threonate on Amazon.) Experiment-wise, I’ll probably look at sleep metrics and Mnemosyne performance; I put off designing a blind self-experiment until after trying some.
…Four subjects correctly stated when they received nicotine, five subjects were unsure, and the remaining two stated incorrectly which treatment they received on each occasion of testing. These numbers are sufficiently close to chance expectation that even the four subjects whose statements corresponded to the treatments received may have been guessing.

In 3, you’re considering adding a new supplement, not stopping a supplement you already use. The I don’t try Adderall case has value $0, the Adderall fails case is worth -$40 (assuming you only bought 10 pills, and this number should be increased by your analysis time and a weighted cost for potential permanent side effects), and the Adderall succeeds case is worth $X-40-4099, where $X is the discounted lifetime value of the increased productivity due to Adderall, minus any discounted long-term side effect costs. If you estimate Adderall will work with p=.5, then you should try out Adderall if you estimate that 0.5 \times (X-4179) > 0 ~> $X>4179$. (Adderall working or not isn’t binary, and so you might be more comfortable breaking down the various how effective Adderall is cases when eliciting X, by coming up with different levels it could work at, their values, and then using a weighted sum to get X. This can also give you a better target with your experiment- this needs to show a benefit of at least Y from Adderall for it to be worth the cost, and I’ve designed it so it has a reasonable chance of showing that.)
The beauty of this stack is that nature has already given us a perfectly packaged combination of caffeine and theanine in the form of green tea, whether a cup of green tea, a bowl of matcha tea, or even a green tea extract supplement as a substitute for a cup of coffee. This is an especially convenient stack to use during a time when you don’t want the excess stimulation of coffee or caffeine in isolation, such as during an evening dinner at a restaurant or in the latter stages of a workday when a cup of coffee might keep you awake too late into the night.
I noticed on SR something I had never seen before, an offer for 150mgx10 of Waklert for ฿13.47 (then, ฿1 = $3.14). I searched and it seemed Sun was somehow manufacturing armodafinil! Interesting. Maybe not cost-effective, but I tried out of curiosity. They look and are packaged the same as the Modalert, but at a higher price-point: 150 rather than 81 rupees. Not entirely sure how to use them: assuming quality is the same, 150mg Waklert is still 100mg less armodafinil than the 250mg Nuvigil pills.
Spaced repetition at midnight: 3.68. (Graphing preceding and following days: ▅▄▆▆▁▅▆▃▆▄█ ▄ ▂▄▄▅) DNB starting 12:55 AM: 30/34/41. Transcribed Sawaragi 2005, then took a walk. DNB starting 6:45 AM: 45/44/33. Decided to take a nap and then take half the armodafinil on awakening, before breakfast. I wound up oversleeping until noon (4:28); since it was so late, I took only half the armodafinil sublingually. I spent the afternoon learning how to do value of information calculations, and then carefully working through 8 or 9 examples for my various pages, which I published on Lesswrong. That was a useful little project. DNB starting 12:09 AM: 30/38/48. (To graph the preceding day and this night: ▇▂█▆▅▃▃▇▇▇▁▂▄ ▅▅▁▁▃▆) Nights: 9:13; 7:24; 9:13; 8:20; 8:31.
Reason: More than 50 percent of your brain is comprised of DHA! Among a big group of elderly Americans, those with the highest blood levels of DHA were about half as apt to develop dementia and 39% as apt to develop Alzheimer’s as those with lower blood levels of DHA over a nine-year period. The top 25% of those with the highest blood DHA got about 180 mg DHA a day or three servings of fish a week, researchers said. In this study, the other major fatty acid in fish oil. EPA had no effect.

Alex recalled one week during his junior year when he had four term papers due. Minutes after waking on Monday, around 7.30am, he swallowed some "immediate-release" Adderall. The drug, along with a steady stream of caffeine, helped him to concentrate during classes and meetings, but he noticed some odd effects; at a morning tutorial, he explained to me in an email, "I alternated between speaking too quickly and thoroughly on some subjects and feeling awkwardly quiet during other points of the discussion." Lunch was a blur: "It's always hard to eat much when on Adderall." That afternoon he went to the library, where he spent "too much time researching a paper rather than actually writing it - a problem that is common to all intellectually curious students on stimulants". At eight he attended a two-hour meeting "with a group focused on student mental health issues". Alex then "took an extended-release Adderall" and worked productively on the paper all night. At eight the next morning he attended a meeting of his student organisation; he felt like "a zombie" and went back to his room. He fell asleep until noon, waking "in time to polish my first paper and hand it in".
Panax ginseng – A review by the Cochrane Collaboration concluded that "there is a lack of convincing evidence to show a cognitive enhancing effect of Panax ginseng in healthy participants and no high quality evidence about its efficacy in patients with dementia."[36] According to the National Center for Complementary and Integrative Health, "[a]lthough Asian ginseng has been widely studied for a variety of uses, research results to date do not conclusively support health claims associated with the herb."[37]
