Deciding what information to include in a presentation is a challenge everyone faces. From the presenter’s perspective, every fact that supports the presentation objective has some value. These might be case studies, data points, primary research, or other elements that drive the point home. Some facts, like primary research studies, might have a high impact while others, like anecdotes and informal stories, have less impact.
On April 30th, South China Morning Post reported that Chinese companies are using brain-reading technology to detect the emotional state of workers. The article was short on details but long on effectiveness claims. If you missed it, the device looks like this:
Sharing a great post from Farnam Street on mental models for problem solving. In my day job, I use a number of these methods for market and product forecasting. One of the most valuable methods is Second Order Thinking:
First-level thinking is simplistic and superficial, and just about everyone can do it (a bad sign for anything involving an attempt at superiority). All the first-level thinker needs is an opinion about the future, as in “The outlook for the company is favorable, meaning the stock will go up.” Second-level thinking is deep, complex and convoluted.
When working with technology vendors, they frequently can’t get past the first level. In their defense, the first order is what’s in front of them – often the next quarter of results. My end user clients, the folks writing checks for technology, are less concerned about the next 3-6 months, but the next 3-6 years. This is where second order thinking comes in. It’s often contentious and imperfect; predicting the future usually is, but this model gives a framework for approaching it.

The top news item this week is the death of Ascendance Biomedical’s CEO, Aaron Traywick. Also, artificial retinas, YouTube’s apparent attack on nootropics content, and the cognitive benefits of music and language training.
Musical training, bilingualism, and executive function: working memory and inhibitory control
Early studies suggested the possibility of a cognitive advantage from musical training and bilingualism but have failed to be replicated by recent findings. To assess whether cognitive benefits from training exist, and how unique they are to each training domain, this study compared musicians and bilinguals to each other, plus to individuals who had expertise in both skills, or neither. The findings confirm previous associations between musicians and improved cognition and extend existing evidence to show that benefits are narrower than expected but can be uniquely attributed to music compared to another specialized auditory skill domain.
Biohacker and CEO of Ascendence Biomedical Aaron Traywick Found Dead in DC
The biohacker community suffered a loss this week. Aaron was found dead in a float tank in DC. It is currently unknown if [Ascendence](https://ascendance.io] will continue operations. Before he died, Ascendance was planning a CRISPR-based trial for treating lung cancer.
YouTube Is Removing Some Nootropics Channels
YouTube deleted at least three nootropics channels over the past three days, leaving members of the community confused and worried that a larger crackdown is coming. Apparently this wasn’t targeted, per the updated Motherboard article, but it leaves more questions than answers about YouTube’s enforcement and appeal guidelines.
New Studies Show Dark Chocolate Can Enhance Cognitive And Immune Health
Although doctors have known about dark chocolate’s health benefits for awhile, these new studies are the first to look specifically at the brains and immune systems of human patients. Flavonoids, an antioxidant, are credited with reducing brain and heart inflammation, but these antioxidants aren’t limited to chocolate. They’re also found in dark vegetables and fruits.
Pupils are taking drugs to help them perform well in exams, says Dr Miriam Stoppard
It’s finals season for many college and university students, which means a raft of “smart drugs” articles. Many of these are overblown and designed to create more FUD than fact.
Scientists develop ‘artificial retina’ in hope to restore sight to the blind
A cheap new artificial retina could soon be used to restore sight to the blind. Researchers from Tel Aviv and Linkoping have developed a small, photoactive film capable of converting light into electrical signals that stimulate light-sensitive nerve cells in the eye. It is hoped that the research could lead to the development of a wireless implant which could be inserted in the eye of a person whose light-sensitive cells have degraded. This technology may be adapted for other biological applications.
Earlier this week, Vice reported that YouTube removed several channels that cover nootropics. I also had trouble publishing Cognitive Enhancement Weekly when MailChimp’s automated service detected a violation of its acceptable use policy. While MailChimp quickly resolved my problem, the YouTube channels have yet to be restored.
I think what’s triggering these automated responses is coverage of kratom. Kratom is an opioid-like herb promising relief from pain, depression and anxiety. The DEA has been on the warpath to ban sales of the herb and make it a Schedule 1 drug, putting it in the same category as heroin and LSD.
Prior to this week, I’ve never mentioned kratom in a mailer. The first time I did, the content was flagged. According the to Vice article, at least one the YouTube content creators believes his coverage of kratom is what triggered the ban. Platforms like YouTube have rules that are applied arbitrarily and they frequently leave no avenue for appeal. Suppressing information, especially for substances with questionable efficacy, benefits no one.
