The Einstein myth: Why the cult of personality is bad for science

We love citing the big names in science. Einstein. Curie. Sagan. Nye The Science Guy. But does that lower the bar for the rest of the workaday scientists out there?

Michelle Thaller: So Jonathan you ask a question that actually gets to the heart of a lot of my ideas about science and culture. And you ask about the celebrity culture. We hear about these famous scientists, it goes Albert Einstein or Stephen Hawking or Neil deGrasse Tyson; we know of these wonderful kind of larger than life personalities, and does that really reflect what the practice of science is?

And in fact, to me, this is actually a deeper question because I think it’s one of the ways that people are kept out of science. We hold up examples about these incredible, heroic, sort of seemingly perfect people, and then we compare ourselves to them. And this is exactly the same as comparing ourselves to supermodels and then looking at the way we look, or comparing ourselves to athletes or to incredibly famous rock stars. So much of our world right now seems to be set up to keep you dissatisfied with who you are and keep you feeling insecure. And in science I keep being asked by people, is it possible that I am smart enough to be a scientist? Do I have what it takes to be a scientist?

And there’s also this sad corollary of all of the people who contact me and say, “Well I see you on television, you must be brilliant. I couldn’t possibly do what you do. I wasn’t good at math. I don’t have the sort of brain that you have.”

All my life this has made me feel different and strange and not right. The very moment that I started to get interested in science I was a very small kid. I was just very curious about space, about geology and rocks, I started to be told, “Wow you’re really different, you’re not the same as all of us,” and “You’re a girl; Wow, that’s even stranger!” Even when people we’re trying to be kind, what they were doing was telling me that in some way I wasn’t right.

The celebrity culture of science and the idea that you need a special personality, a special type of brain to do science, are some of the most harmful ideas about science that our culture has come up with. I often have to deal with – for example, the idea of Albert Einstein: Albert Einstein was incredibly brilliant and he revolutionized our understanding of the universe. But there’s a myth about him—and you may be familiar with it—that Albert Einstein “wasn’t really part of the scientific establishment,” he was “just working in a patent office,” “he just pulled all of this out of his brain,” “it was just him working alone.” And that wasn’t true at all! Albert Einstein was, in fact, part of science.

He was a professor, he was finishing up his doctorate when he was working in the patent office. He was part of a culture and the establishment of science. And he wasn’t working alone. Some of the major parts of his theory, for example the special theory of relativity that deals with how time and slows down when you go close to the speed of light, had been largely been formalized and set up before by people like Lorentz, and even parts of general relativity, his idea about gravitation and the curvature of space, had been done by people like LeMaitre and others.

Einstein was absolutely brilliant at seeing that different theories that people were working on could come together into a wonderful coherent whole. Even he admitted he wasn’t particularly great at the mathematics and he had other people that assisted him with actually formalizing the mathematics of how gravity could work.

So Albert Einstein himself would’ve said that he was brilliant in collaboration, that he actually pulled lots of things together. He wasn’t just a lone person pulling stuff out of his head from first principles just by magic. The idea that “science is done by brilliant people who are different than you” is just a way to keep people OUT of science.

There is nothing more difficult about learning science than there is about learning anything. It takes years to learn all the physics you need, for example, to get a doctorate in physics, but I always looked at it like learning a foreign language: you learn things slowly step-by-step, you practice; it’s difficult, but you keep going.

I don’t know why we set science as something different than learning a language. Nobody would say to you “you simply do not have the mental capability to learn French.” Everybody can. There are some people that are naturally brilliant at languages, it may come faster to them, it may be something that they don’t have to work on as hard as other people, but there’s nobody that can’t learn a language, and there’s nothing magical about science.

I have a brain that tends towards the creative and the imaginative, I’m not very linear, I’m not very logical, I’m not very organized, and I kept being told I didn’t have the “right personality to do science.” And there’s nothing about what science actually is that demands any type of personality. You can learn something in many different ways, and honestly, you can learn anything if you take the time and if you practice.

Science can be taught in a very intimidating way, and I suffered from that. I spent most of my college years so scared and confused I wouldn’t even ask the professor a question because I felt so much shame that I basically hadn’t understood anything the whole semester, but you take things over and over again, and slowly they build up.

The idea that we are led by single, brilliant people is an idea that, I think, has at its core privilege and exclusion. And it’s time for us to take back science, imagination, creativity. You are enough, right now, to do this. You are smart enough, you are brilliant enough, you have everything you need. You can be a scientist if you want to, you don’t need me to actually turn something on inside your mind, you don’t need to have been born with something magical. You’re a scientist, and you can just ask a question.

We love citing the big names in science. Einstein. Curie. Sagan. Nye (The Science Guy). But Michelle Thaller of NASA thinks that perhaps the whole so-called 'celebrity scientist' idea makes it more difficult for regular people to think they could ever be one. "The idea that we are led by single, brilliant people is an idea that, I think, has at its core privilege and exclusion," she posits, "And it’s time for us to take back science, imagination, creativity."

Does conscious AI deserve rights?

If machines develop consciousness, or if we manage to give it to them, the human-robot dynamic will forever be different.

  • Does AI—and, more specifically, conscious AI—deserve moral rights? In this thought exploration, evolutionary biologist Richard Dawkins, ethics and tech professor Joanna Bryson, philosopher and cognitive scientist Susan Schneider, physicist Max Tegmark, philosopher Peter Singer, and bioethicist Glenn Cohen all weigh in on the question of AI rights.
  • Given the grave tragedy of slavery throughout human history, philosophers and technologists must answer this question ahead of technological development to avoid humanity creating a slave class of conscious beings.
  • One potential safeguard against that? Regulation. Once we define the context in which AI requires rights, the simplest solution may be to not build that thing.

  • 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.

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.

Predicting PTSD symptoms becomes possible with a new test

An algorithm may allow doctors to assess PTSD candidates for early intervention after traumatic ER visits.

Technology & Innovation
  • 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.

Going forward

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.
