How to increase your will power? Make a Ulysses pact with yourself
The only thing between you and your better self is your brain. Programmed to maximize short term reward, we often find ourselves struggling between what we want and what we want to want.
David Eagleman is a neuroscientist and a New York Times bestselling author. He directs the Laboratory for Perception and Action at the Baylor College of Medicine, where he also directs the Initiative on Neuroscience and Law. He is best known for his work on time perception, brain plasticity, synesthesia, and neurolaw.
Beyond his 100+ academic publications, he has published many popular books. His bestselling book Incognito: The Secret Lives of the Brain, explores the neuroscience "under the hood" of the conscious mind: all the aspects of neural function to which we have no awareness or access. His work of fiction, SUM, is an international bestseller published in 28 languages and turned into two operas. Why the Net Matters examines what the advent of the internet means on the timescale of civilizations. The award-winning Wednesday is Indigo Blue explores the neurological condition of synesthesia, in which the senses are blended.
Eagleman is a TED speaker, a Guggenheim Fellow, a winner of the McGovern Award for Excellence in Biomedical Communication, a Next Generation Texas Fellow, Vice-Chair on the World Economic Forum's Global Agenda Council on Neuroscience & Behaviour, a research fellow in the Institute for Ethics and Emerging Technologies, Chief Scientific Advisor for the Mind Science Foundation, and a board member of The Long Now Foundation.

DAVID EAGLEMAN: Go back 3,000 years to Ulysses, who fought in the Trojan War and was coming home to his island of Ithaca on his ships with his men, and he realized that he had this amazing opportunity, which is he was going to pass the Island of the Sirens. And he knew that the sirens sang so beautifully and were so seductive that mortal men would crash their ships into the rocks, and they’d all die every time. If you heard the song of the sirens you were going to die.
He wanted to hear the song of the sirens, so what did he do? The Ulysses of present sound mind made a contract with the future Ulysses. He said, “I know that guy is going to behave badly when he hears the siren’s song.” So what did he do? He lashed himself to the mast, exactly, and he filled his men’s ears with beeswax, and he said, "No matter what I do, keep on rowing." Just ignore everything, keep on going. And that way he got to hear the siren’s song but he didn’t crash in the rocks because he was lashed to the mast. And so this is what is known as a “Ulysses contract”, which is your present self making a contract with your future self. Penning in, constraining the behavior of your future self so that it has to do the right thing given your long-term thinking that you’re doing now. And so when it comes to something like the cookies, the Ulysses contract, it’s more than “I’m going to eat it or not eat it.” It can be something like, “Okay, look, if I eat cookies, I’m going to promise my spouse that I’ll go to the gym tonight.” That’s the kind of way that we can bring these sorts of things into our own life.
And so I'll give you several examples. I want to say is so what we’ve seen so far is that there’s this great seduction in the now.
And so if we want to do something where we actually are navigating our future selves in a better way we have to establish these kinds of contracts with ourselves. This is one of the most important sort of life lessons that I’ve got. I mean take something like New Year’s resolutions. Everybody has really good New Year’s resolutions and believes they’re going to do it. And by the end of January for almost everybody these things have fallen away. Why? It’s not because you didn’t mean it in January. It’s because you didn’t set up the structures in your life, the Ulysses contracts to make sure that that went through. It’s not enough to make a promise and a resolution with good intention. You need to understand what’s actually happening so that you can do something about it.
So what I want to do is suggest actionable steps by which we can actually keep our resolutions to ourselves a little bit longer.
So the first one is building fences around yourself by minimizing temptation. So, for example, in Alcoholics Anonymous the very first thing they tell you is you’ve got to clear all the alcohol out of your house. Why? It’s because on a festive Friday night or a lonely Sunday night you’re going to go and drink. Even if you think, “No, I’m done. I’m not going to drink but I’m going to keep those in there.”
With smokers the first thing they’re told in these rehab programs is: don’t hang out with other smokers. With drug addicts who are trying to quit the first thing they’re told in drug rehab programs is: make sure you never carry more than 20 bucks of cash with you.
Because if you have the cash, no matter what your resolution is, you meet somebody in the alley who offers you drugs and you feel like, “Oh yeah, I’ve got this money anyway,” and so you do it.
So the issue is not-tempting temptation.
I was recently on a college campus giving a talk and I met these kids afterwards who during finals week what they do is they swap Facebook passwords with each other and they change those passwords so they can’t log into Facebook when they’re supposed to be studying. And then at the end of finals when it’s all over they give each other’s passwords back. It was very clever and that’s a beautiful sort of Ulysses contract where a week before finals you’re knowing about the temptations that you’re going to give into and you’re doing something to take care of those. By now a lot has been said about the marshmallow test. You guys probably know about this where children are asked you can eat this one marshmallow now or if you wait until I come back you can get two marshmallows.
People talk about this in terms of the resolution that little kids have and how good they are at resisting temptation and stuff but there’s something that’s often overlooked here which is that one of the most common strategies that kids use was simply covering their eyes. Just clapping their hands over their eyes so they’re not looking at the marshmallow. And it turns out that’s a very effective strategy. And so when we think about minimizing temptations whatever your temptations are in life just think about the ways that you can actually contractually minimize that temptation so it’s not there. Not a fake thing or anything. Oh yeah, if it’s in the back of the cabinet I won’t do it but like actually get rid of the temptation.
The only thing between you and your better self is your brain. Programmed to maximize short term reward, we often find ourselves struggling between what we want in the moment and what we'll gain in the long term if we forgo immediate gratification. As neuroscientist David Eagleman reveals, the ancient wisdom of Ulysses remains useful today as a way to contextualize current scientific research. Before temptation strikes, it pays to have a plan for when it arrives. By making a contract with your future self—as Ulysses did with his crew—you can avoid occasions of indulgence. And when you do give into immediate satisfaction, you can build in supports to keep it from wreaking havoc on your life.

Duke University researchers might have solved a half-century old problem.
- Duke University researchers created a hydrogel that appears to be as strong and flexible as human cartilage.
- The blend of three polymers provides enough flexibility and durability to mimic the knee.
- The next step is to test this hydrogel in sheep; human use can take at least three years.
Duke researchers have developed the first gel-based synthetic cartilage with the strength of the real thing. A quarter-sized disc of the material can withstand the weight of a 100-pound kettlebell without tearing or losing its shape.

An algorithm may allow doctors to assess PTSD candidates for early intervention after traumatic ER visits.
- 10-15% of people visiting emergency rooms eventually develop symptoms of long-lasting PTSD.
- Early treatment is available but there's been no way to tell who needs it.
- Using clinical data already being collected, machine learning can identify who's at risk.
The psychological scars a traumatic experience can leave behind may have a more profound effect on a person than the original traumatic experience. Long after an acute emergency is resolved, victims of post-traumatic stress disorder (PTSD) continue to suffer its consequences.
In the U.S. some 30 million patients are annually treated in emergency departments (EDs) for a range of traumatic injuries. Add to that urgent admissions to the ED with the onset of COVID-19 symptoms. Health experts predict that some 10 percent to 15 percent of these people will develop long-lasting PTSD within a year of the initial incident. While there are interventions that can help individuals avoid PTSD, there's been no reliable way to identify those most likely to need it.
That may now have changed. A multi-disciplinary team of researchers has developed a method for predicting who is most likely to develop PTSD after a traumatic emergency-room experience. Their study is published in the journal Nature Medicine.
70 data points and machine learning

Study lead author Katharina Schultebraucks of Columbia University's Department Vagelos College of Physicians and Surgeons says:
"For many trauma patients, the ED visit is often their sole contact with the health care system. The time immediately after a traumatic injury is a critical window for identifying people at risk for PTSD and arranging appropriate follow-up treatment. The earlier we can treat those at risk, the better the likely outcomes."
The new PTSD test uses machine learning and 70 clinical data points plus a clinical stress-level assessment to develop a PTSD score for an individual that identifies their risk of acquiring the condition.
Among the 70 data points are stress hormone levels, inflammatory signals, high blood pressure, and an anxiety-level assessment. Says Schultebraucks, "We selected measures that are routinely collected in the ED and logged in the electronic medical record, plus answers to a few short questions about the psychological stress response. The idea was to create a tool that would be universally available and would add little burden to ED personnel."
Researchers used data from adult trauma survivors in Atlanta, Georgia (377 individuals) and New York City (221 individuals) to test their system.
Of this cohort, 90 percent of those predicted to be at high risk developed long-lasting PTSD symptoms within a year of the initial traumatic event — just 5 percent of people who never developed PTSD symptoms had been erroneously identified as being at risk.
On the other side of the coin, 29 percent of individuals were 'false negatives," tagged by the algorithm as not being at risk of PTSD, but then developing symptoms.

Schultebraucks looks forward to more testing as the researchers continue to refine their algorithm and to instill confidence in the approach among ED clinicians: "Because previous models for predicting PTSD risk have not been validated in independent samples like our model, they haven't been adopted in clinical practice." She expects that, "Testing and validation of our model in larger samples will be necessary for the algorithm to be ready-to-use in the general population."
"Currently only 7% of level-1 trauma centers routinely screen for PTSD," notes Schultebraucks. "We hope that the algorithm will provide ED clinicians with a rapid, automatic readout that they could use for discharge planning and the prevention of PTSD." She envisions the algorithm being implemented in the future as a feature of electronic medical records.
The researchers also plan to test their algorithm at predicting PTSD in people whose traumatic experiences come in the form of health events such as heart attacks and strokes, as opposed to visits to the emergency department.
What would it be like to experience the 4th dimension?
Physicists have understood at least theoretically, that there may be higher dimensions, besides our normal three. The first clue came in 1905 when Einstein developed his theory of special relativity. Of course, by dimensions we’re talking about length, width, and height. Generally speaking, when we talk about a fourth dimension, it’s considered space-time. But here, physicists mean a spatial dimension beyond the normal three, not a parallel universe, as such dimensions are mistaken for in popular sci-fi shows.
Vaccines find more success in development than any other kind of drug, but have been relatively neglected in recent decades.
Vaccines are more likely to get through clinical trials than any other type of drug — but have been given relatively little pharmaceutical industry support during the last two decades, according to a new study by MIT scholars.
