“Distracted from distraction by distraction”*…
Don Moynihan argues that here has been a shift in the character– the instincts, the motivations, and thus the patterns of decision and action– of our government…
One of the strangest moments to emerge from the U.S. kidnapping of Nicolás Maduro was the flurry of images posted by President Trump on Truth Social. It felt a bit like a student who can’t decide which spring break photos look cutest, so they just upload them all.
The intent seemed to be to create an iconic image reminiscent of the White House Situation Room during the raid that killed Osama bin Laden—a gathering of stoic men (no girls allowed!) staring grimly at some unseen screen. The message: “Look how serious and important our work is!” Yet, the staged nature of these photos undermines that effect, leaving the whole scene feeling less like history in the making and more like an amateur theater production of a Broadway classic.
In one image, the Director of the CIA, the Chair of the Joint Chiefs of Staff, and the Secretary of Defense are grouped around a laptop. Behind them, unmistakably, a screen displays a feed from X—complete with a prominent yellow emoji. In other pictures, “Venezuela” appears to be in the search box.
With the best intelligence systems in the world at their fingertips, they were checking X in the midst of the mission? Combined with the curtains separating some section of Mar‑A‑Lago from the rest of the President’s resort, the images create an almost surreal air. It felt as if a group of twelve-year-old boys in a basement had been handed control of the most lethal military in history—and were using it to boost their online brands.
Trump is undoubtedly the American president who has most effectively wielded social media: drawing attention, reshaping norms, and fueling conspiracy theories. The successful use of social media, for example, turned avowed MAGA isolationists into enthusiastic colonial imperialists overnight.
But I want to suggest that what we are witnessing from the Trump administration is not just skillful manipulation of social media—it’s something more profoundly worrying. Today, we live in a clicktatorship, ruled by a LOLviathan. Our algothracy is governed by poster brains.
It’s worth remembering that social media operates like a drug, feeding us dopamine and rewiring our brains’ reward pathways. The fundamentally unhealthy dynamics are worsened by the fact that standing out online often demands being awful—channeling negative emotions like anger and outrage, usually based on misinformation or conspiracy theories.
None of this is new. Indeed, there is a booming political science literature on the effects of social media on voter behavior. Chris Hayes and others have written persuasively about the how toxic attention farming is for us personally and for our democracy. But I want to make the case that we should also consider how social media it is affecting how policymakers use public power.
What I’m arguing is that the Trump administration isn’t just using social media to shape a narrative. Many of its members are deeply addicted to it. We would be concerned if a senior government official was an alcoholic or drug addict, knowing it could impair judgment and decisionmaking. But we should be equally concerned about Pete Hegseth and Elon Musk’s social media compulsions—just as much as their alcohol or ketamine use, respectively.
Overexposure to online engagement has cooked the brains of some of the most powerful people in the world. This is not exclusively an American phenomenon. President Yoon Suk Yeol seemed to have genuinely believed online conspiracy theories about election fraud, motivating his declaration of martial law and triggering a constitutional crisis, and his eventual arrest, in Korea.
But in the US government, poster brain feels endemic. The Trump administration is made up of a cabinet of posters. For many, that’s how they won Trump’s attention. The head of the FBI, for example, is a podcaster—that’s his main qualifier for the job.
They view the world through a social media lens in a way that is plausibly corrupting their judgment and undermining their performance. Lets think through how poster brain can affect how people in government operate…
[Moynihan explores, with illustrative examples, online bubbles, conflicts between professional and online indentities, the degradation of professional norms and work practices, and the altering of decision-making to be responsive to social media– to create content]
I’m just scratching the surface here. Pick any federal agency, and you can find examples of poster brains making important decisions. This trend is likely to only get worse as digital natives enter key government roles. And there are likely a host of other ways these patterns are undermining the professional behavior of people in government that I have not identified. In particular, the Trump administration represents the intersection of poster brain, personalism, and authoritarianism that seems especially toxic…
… The bottom line is that it we need to take more seriously how social media has rewired the brains—and behavior—of those running our country.

In 1762, Johan Carl Wilcke invented the electrophorus, a device that revolutionized our understanding of static electricity. This tool paved the way for advancements in batteries, capacitors, and ESD control. Today, static electricity management is vital in electronics, aerospace, and manufacturing, protecting sensitive components and improving reliability. Wilcke’s work shows how simple ideas can impact industries for centuries. #StaticElectricity #ESD #Innovation #Electrophorus

Rubbing a balloon on your hair can build a significant electrical charge. Water droplets have the same issue when they slide across a hydrophobic, electrically-insulated surface. A new study models why these charges build up and tests the model both experimentally and through simulation. They focused their theory on three effects that determine how much charge builds up. The first is a two-way chemical reaction that continuously creates charge at the interface, with positive charge building in the drop. Secondly, the drop’s contact angle with the surface sets how many protons can build up at the contact line, thereby affecting the electrical field they generate. And, finally, fluid motion at the rear of the drop deflects protons upward, shifting the electrical field. In particular, their model predicts that the higher contact angles of hydrophobic surfaces should increase charge build-up and faster sliding velocities should slow charge build-up, both of which agree with experiments.
The model should help researchers understand various charging scenarios, like those found on self-cleaning surfaces, in inkjet printing, and in semiconductor manufacturing. In the last scenario, rinsing semiconductor wafers in ultrapure water can build up charges in the kilovolt range, which is enough to damage the product. (Image credit: D. Carlson; research credit: A. Ratschow et al.; via APS Physics)

Why a spritz of #water before grinding #coffee yields less waste, tastier #espresso
Paper published in the journal Matter shows adding a single squirt of water to #coffebeans before grinding significantly reduces #staticelectricity of the resulting grounds. This, reduces clumping during brewing, yielding less waste and strong, consistent flow needed to produce a tasty cup of espresso. Good baristas already employ the water trick; it's known as #RossDroplet technique
