Dr. Neil deGrasse Tyson is the showman supreme of astrophysics. I have long admired how he brings complex scientific ideas to the general public with clarity and humor. So when Jamie Canfield, our president, offered me the chance to accompany her to his talk at the Long Center on April 14th, I did not hesitate. The title, “Science Under Siege,” felt especially relevant in today’s climate, where science funding is under pressure and public discourse around science is becoming increasingly strained.
As expected, the showman did not disappoint. The roughly 2,500-seat auditorium was nearly full, with an audience that spanned generations, from young children to seniors. For over two hours, he held their attention with ease. There were stories, personal anecdotes, moments of humor, interactions with children in the audience, and even live tweeting during the talk. His connection with Austin, mentioned at different points during the talk, elicited warm applause from the audience. From a presentation standpoint, it was polished and highly engaging.
At the same time, the subject itself was serious. Science, as he framed it, is facing multiple challenges, including funding cuts, policy decisions that run counter to established scientific understanding, and a broader cultural polarization that affects how science is perceived.
Dr. Tyson chose to approach these issues through his own experiences. He spoke about his journey, his perspective on the current situation, and his role as a public figure advocating for science. Early on, he made a point of distancing the issue from simple political binaries. According to him, this is not a matter of Republicans versus Democrats or Right versus Left. He supported this with historical examples, highlighting which administrations increased or decreased science funding. Some of these examples were surprising. For instance, the largest percentage increase came under Eisenhower, while some of the smallest increases occurred under Democratic presidents.
He then moved to the idea of bias and how easily we label institutions and individuals. Fox Corporation served as one of his examples. He spoke about his involvement in reviving Cosmos and used that to challenge the perception of Fox as a monolithic entity. His argument was that such labels often obscure more than they reveal.
This line of thought continued into a broader discussion about political identity and attitudes toward science. He argued, quite effectively, that being right-leaning does not automatically make someone anti-science, just as being left-leaning does not guarantee the opposite. He presented this in a way that kept the audience laughing, but the underlying point was clear. If we claim to value scientific thinking, then we have to be guided by evidence rather than assumptions.
A significant portion of the talk focused on his role as an “influencer,” particularly on social media. He described how he deliberately structures his posts to reach beyond his existing audience. To do this, he uses a set of keywords that cut across cultural and political lines, including religion, media, public figures, and contentious social topics. He then shared examples of tweets built around these keywords and demonstrated how they reached people outside his usual circle. Some of the reactions were negative, including people blocking him, but he viewed that as confirmation that he was, in fact, reaching new audiences.
His broader message here was that it is not enough to speak within one’s own echo chamber. If science is to be defended effectively, its advocates need to engage with those who may not already agree.
He did point to a few reasons for optimism. Certain policy decisions, particularly around vaccines, had been challenged successfully in the courts. Proposed budget cuts had also been pushed back, in some cases with bipartisan support. As he wrapped up, he mentioned a documentary he is involved in, Shot in the Arm, which is expected to be released later this year. He added that a private screener could be requested by emailing maureen@blackvalleyfilms.com. He also acknowledged the book Science Under Siege: How to Fight the Five Most Powerful Forces That Threaten Our World by Michael E. Mann and Peter J. Hotez, from which the talk takes its title. The evening ended with strong applause and a call from Dr. Tyson for everyone to speak out in support of science.
And yet, despite all this, I found myself underwhelmed.
Going in, I expected that the talk would include politics alongside science. That seemed inevitable given the title. What I did not expect was how little actual science would feature in the discussion. By the end, I found myself asking a simple question: what did I really learn? I am not sure I came away with a clear answer.
There were certainly interesting moments. His argument about not reducing science to political identity was worth hearing. The explanation behind his social media strategy was new to me, even though I was already familiar with many of the tweets he referenced. But beyond that, I was left wanting more. What is the broader scientific community doing in response to these challenges? What role can someone like me, or any other science enthusiast, realistically play?
The talk, at least to me, felt more centered on him than on the subject itself. Some self-reference is expected, of course, especially from a public figure of his stature. Still, it seemed to take up more space than it needed to. Given that this was a ticketed event, and not an inexpensive one, I could not help but wonder if that time might have been better spent on other topics.
I also kept thinking about the younger audience members. One young girl who was invited on stage will probably remember that moment for years. But how much of the rest of the discussion would have connected with her, or with other children in attendance? Even a small segment focused on actual science might have made a difference there.
In conversations afterward, both in person and online, I found that I was not alone in this reaction. Many people had expected at least some scientific content and were surprised by its absence.
That said, I can see how this talk might have landed differently for others. For those who are not closely following the current challenges facing science, or who are not familiar with Dr. Tyson’s social media presence, much of this may have been informative and even eye-opening.
For me, however, it felt more like a performance than a deep exploration of the topic. It was well delivered, often entertaining, and clearly resonated with much of the audience. But I had gone in hoping to learn something new about science itself, and on that front, it did not quite deliver. If I were looking for a well-presented set, I might have gone to Fifth Street rather than the Long Center, to be honest.
And in hindsight, I might have learned more by sticking with my original plan and attending the local Astronomy on Tap event instead. Then again, that may simply be a matter of what I was looking for going in.
