Is Your Negativity Getting in the Way of Your Creativity?
Do your meetings and brainstorms always end with a pile of decimated ideas? Learn to overcome negativity bias and obstructive tendencies.

We all know a Debbie downer. That one person that always knows what could go wrong, and lets you know about those horrible things as soon as you propose any new idea. They rarely have anything in the way of new proposals, but they know for sure that your idea is the worst thing they've ever heard. Why do they still make people like that? Wouldn’t optimism be better for everybody?
But, what if we told you that their tendency to bring everyone down is really a survival skill—one that drove human evolution.
Adam Hansen, author of Outsmart Your Instincts, argues that our early human ancestors without food surpluses found that the status quo of what worked well enough was much preferable to taking risks with any chance of failure. The DNA that we have is that of the survivors, the ones who didn’t take large risks and lived to tell the tale. “We are the descendants of the savants of risk aversion,” Hansen claims. This negativity bias is irrational but is a bias towards caution, which is a tendency we still value, as evidenced by our idioms of “curiosity killed the cat,” “better the devil you know,” and, “leave well enough alone.”

The negativity bias is a well-studied and heavily documented phenomenon with implications for nearly every aspect of our lives. One area where it affects us daily, almost without our noticing it, is in our decision making. Nearly all people are more risk averse than they think they are.
In one study, young children took part in response inhibition activities. Half of them were rewarded for the desired behavior, and half were punished (by taking away a visible reward) for failure. It was found that punishment was more effective at getting the children to follow along at all age levels than reward was. Another study showed that we view the loss of resources as being more important than the gain of resources, even when the amounts in question are similar.
Of course, not everybody is pessimistic all the time, so you can overcome the negativity bias.
Understanding your biases is the first step in overcoming them. The idea that humans are perfectly rational beings is a fairly new one, historically speaking, and becoming aware that your first instinct is going to be irrational is the second step. Julia Galef, co-founder of the Center for Applied Rationality, makes the case that you should never accept your brain's first answer to anything. "Your brain is lazy," Galef says. "Don’t take it personally, my brain’s also lazy. Everyone’s brain is lazy. It’s how the human brain is built."
Hansen too calls negative reflexes "cognitively lazy". It's much easier to say something is wrong than to think about how it could become right. While it takes cognitive effort to reject your first impulse and make the more rational or helpful observation, it is one that can offer huge dividends.
The best solution to the problem is feedback, says management expert Jennifer Brown. Being aware of when you do get hung up on the possible negatives more than you should is the best way of starting to view the negatives in the right proportion to their reality. She has a similar suggestion about how to overcome confirmation biases.

For Adam Hansen, the solution is to work on new habits. While your instinct will be to find the fault in a new idea straight off, try finding what you like about it first. Old habits die hard, but it can be done. He also recommends that businesses ban the phrase “I don’t like it” in meetings, unless it comes with further explanation.
"Every idea is really a compound of ideas. It has all these facets, all these little pieces, and so even if it’s a horrible idea overall, you can still isolate something in there [that you like].
What value could be there? What benefit could come out of this? And what potential are you starting to see because you’re not dismissing it out of hand? Once you start considering ideas for the provocative value, maybe more than just their immediate merits, really cool stuff starts to happen. Every idea can become this multiplicative force, and now I’m not building a shrine to this one idea. I’m simply using it to help me come up with even better ideas. Once you’ve done that, your mind is in a much better frame to take on the problems with the idea, the very real issues," Hansen says.
While we all tend to view negative outcomes as more severe than they are, and view the whole as less positive than the sum of its parts, we can overcome this ancient irrationality with feedback, reflection on our actions, and a new vocabulary of "How might we..." or "That's great, and..." that opens up possibilities rather than shooting them down. Overcoming the negativity bias we all share can be a profitable change.

How tiny bioelectronic implants may someday replace pharmaceutical drugs
Scientists are using bioelectronic medicine to treat inflammatory diseases, an approach that capitalizes on the ancient "hardwiring" of the nervous system.
Left: The vagus nerve, the body's longest cranial nerve. Right: Vagus nerve stimulation implant by SetPoint Medical.
- Bioelectronic medicine is an emerging field that focuses on manipulating the nervous system to treat diseases.
- Clinical studies show that using electronic devices to stimulate the vagus nerve is effective at treating inflammatory diseases like rheumatoid arthritis.
- Although it's not yet approved by the US Food and Drug Administration, vagus nerve stimulation may also prove effective at treating other diseases like cancer, diabetes and depression.
The nervous system’s ancient reflexes
<p>You accidentally place your hand on a hot stove. Almost instantaneously, your hand withdraws.</p><p>What triggered your hand to move? The answer is <em>not</em> that you consciously decided the stove was hot and you should move your hand. Rather, it was a reflex: Skin receptors on your hand sent nerve impulses to the spinal cord, which ultimately sent back motor neurons that caused your hand to move away. This all occurred before your "conscious brain" realized what happened.</p><p>Similarly, the nervous system has reflexes that protect individual cells in the body.</p><p>"The nervous system evolved because we need to respond to stimuli in the environment," said Dr. Tracey. "Neural signals don't come from the brain down first. Instead, when something happens in the environment, our peripheral nervous system senses it and sends a signal to the central nervous system, which comprises the brain and spinal cord. And then the nervous system responds to correct the problem."</p><p>So, what if scientists could "hack" into the nervous system, manipulating the electrical activity in the nervous system to control molecular processes and produce desirable outcomes? That's the chief goal of bioelectronic medicine.</p><p>"There are billions of neurons in the body that interact with almost every cell in the body, and at each of those nerve endings, molecular signals control molecular mechanisms that can be defined and mapped, and potentially put under control," Dr. Tracey said in a <a href="https://www.youtube.com/watch?v=AJH9KsMKi5M" target="_blank">TED Talk</a>.</p><p>"Many of these mechanisms are also involved in important diseases, like cancer, Alzheimer's, diabetes, hypertension and shock. It's very plausible that finding neural signals to control those mechanisms will hold promises for devices replacing some of today's medication for those diseases."</p><p>How can scientists hack the nervous system? For years, researchers in the field of bioelectronic medicine have zeroed in on the longest cranial nerve in the body: the vagus nerve.</p>The vagus nerve

<p>The vagus nerve ("vagus" meaning "wandering" in Latin) comprises two nerve branches that stretch from the brainstem down to the chest and abdomen, where nerve fibers connect to organs. Electrical signals constantly travel up and down the vagus nerve, facilitating communication between the brain and other parts of the body.</p><p>One aspect of this back-and-forth communication is inflammation. When the immune system detects injury or attack, it automatically triggers an inflammatory response, which helps heal injuries and fend off invaders. But when not deployed properly, inflammation can become excessive, exacerbating the original problem and potentially contributing to diseases.</p><p>In 2002, Dr. Tracey and his colleagues discovered that the nervous system plays a key role in monitoring and modifying inflammation. This occurs through a process called the <a href="https://www.nature.com/articles/nature01321" target="_blank" rel="noopener noreferrer">inflammatory reflex</a>. In simple terms, it works like this: When the nervous system detects inflammatory stimuli, it reflexively (and subconsciously) deploys electrical signals through the vagus nerve that trigger anti-inflammatory molecular processes.</p><p>In rodent experiments, Dr. Tracey and his colleagues observed that electrical signals traveling through the vagus nerve control TNF, a protein that, in excess, causes inflammation. These electrical signals travel through the vagus nerve to the spleen. There, electrical signals are converted to chemical signals, triggering a molecular process that ultimately makes TNF, which exacerbates conditions like rheumatoid arthritis.</p><p>The incredible chain reaction of the inflammatory reflex was observed by Dr. Tracey and his colleagues in greater detail through rodent experiments. When inflammatory stimuli are detected, the nervous system sends electrical signals that travel through the vagus nerve to the spleen. There, the electrical signals are converted to chemical signals, which trigger the spleen to create a white blood cell called a T cell, which then creates a neurotransmitter called acetylcholine. The acetylcholine interacts with macrophages, which are a specific type of white blood cell that creates TNF, a protein that, in excess, causes inflammation. At that point, the acetylcholine triggers the macrophages to stop overproducing TNF – or inflammation.</p><p>Experiments showed that when a specific part of the body is inflamed, specific fibers within the vagus nerve start firing. Dr. Tracey and his colleagues were able to map these relationships. More importantly, they were able to stimulate specific parts of the vagus nerve to "shut off" inflammation.</p><p>What's more, clinical trials show that vagus nerve stimulation not only "shuts off" inflammation, but also triggers the production of cells that promote healing.</p><p>"In animal experiments, we understand how this works," Dr. Tracey said. "And now we have clinical trials showing that the human response is what's predicted by the lab experiments. Many scientific thresholds have been crossed in the clinic and the lab. We're literally at the point of regulatory steps and stages, and then marketing and distribution before this idea takes off."<br></p>The future of bioelectronic medicine

In the future, it may also be used to treat cancer, diabetes, and depression.

<p>Vagus nerve stimulation is currently awaiting approval by the US Food and Drug Administration, but so far, it's proven safe and effective in clinical trials on humans. Dr. Tracey said vagus nerve stimulation could become a common treatment for a wide range of diseases, including cancer, Alzheimer's, diabetes, hypertension, shock, depression and diabetes.</p><p>"To the extent that inflammation is the problem in the disease, then stopping inflammation or suppressing the inflammation with vagus nerve stimulation or bioelectronic approaches will be beneficial and therapeutic," he said.</p><p>Receiving vagus nerve stimulation would require having an electronic device, about the size of lima bean, surgically implanted in your neck during a 30-minute procedure. A couple of weeks later, you'd visit, say, your rheumatologist, who would activate the device and determine the right dosage. The stimulation would take a few minutes each day, and it'd likely be unnoticeable.</p><p>But the most revolutionary aspect of bioelectronic medicine, according to Dr. Tracey, is that approaches like vagus nerve stimulation wouldn't come with harmful and potentially deadly side effects, as many pharmaceutical drugs currently do.</p><p>"A device on a nerve is not going to have systemic side effects on the body like taking a steroid does," Dr. Tracey said. "It's a powerful concept that, frankly, scientists are quite accepting of—it's actually quite amazing. But the idea of adopting this into practice is going to take another 10 or 20 years, because it's hard for physicians, who've spent their lives writing prescriptions for pills or injections, that a computer chip can replace the drug."</p><p>But patients could also play a role in advancing bioelectronic medicine.</p><p>"There's a huge demand in this patient cohort for something better than they're taking now," Dr. Tracey said. "Patients don't want to take a drug with a black-box warning, costs $100,000 a year and works half the time."</p><p>Michael Dowling, president and CEO of Northwell Health, elaborated:</p><p>"Why would patients pursue a drug regimen when they could opt for a few electronic pulses? Is it possible that treatments like this, pulses through electronic devices, could replace some drugs in the coming years as preferred treatments? Tracey believes it is, and that is perhaps why the pharmaceutical industry closely follows his work."</p><p>Over the long term, bioelectronic approaches are unlikely to completely replace pharmaceutical drugs, but they could replace many, or at least be used as supplemental treatments.</p><p>Dr. Tracey is optimistic about the future of the field.</p><p>"It's going to spawn a huge new industry that will rival the pharmaceutical industry in the next 50 years," he said. "This is no longer just a startup industry. [...] It's going to be very interesting to see the explosive growth that's going to occur."</p>Smart vultures never, ever cross the Spain-Portugal border. Why?
The first rule of Vulture Club: stay out of Portugal.
So you're a vulture, riding the thermals that rise up over Iberia. Your way of life is ancient, ruled by needs and instincts that are way older than the human civilization that has overtaken the peninsula below, and the entire planet.
Best. Science. Fiction. Show. Ever.
"The Expanse" is the best vision I've ever seen of a space-faring future that may be just a few generations away.
- Want three reasons why that headline is justified? Characters and acting, universe building, and science.
- For those who don't know, "The Expanse" is a series that's run on SyFy and Amazon Prime set about 200 years in the future in a mostly settled solar system with three waring factions: Earth, Mars, and Belters.
- No other show I know of manages to use real science so adeptly in the service of its story and its grand universe building.

<p>Now, I get it if you don't agree with me. I love "Star Trek" and I thought "Battlestar Galactica" (the new one) was amazing and I do adore "The Mandalorian". They are all fun and important and worth watching and thinking about. And maybe you love them more than anything else. But when you sum up the acting, the universe building, and the use of real science where it matters, I think nothing can beat "The Expanse". And with a <a href="https://www.rottentomatoes.com/tv/the_expanse" target="_blank">Rotten Tomato</a> average rating of 93%, I'm clearly not the only one who feels this way.</p><p>Best.</p><p>Show.</p><p>Ever. </p>How exercise changes your brain biology and protects your mental health
Contrary to what some might think, the brain is a very plastic organ.
As with many other physicians, recommending physical activity to patients was just a doctor chore for me – until a few years ago. That was because I myself was not very active.

By 2050, there may be more plastic than fish in the sea.
