The majority (63%) of citizens trust scientists. Only 5% distrust scientists.
There is less trust for politicized topics (climate science) and of government or business scientists
It's critical to support science at universities, where people trust the results

We observe the development of a division of labor from simple selfish behavior and communication between the members of the system. The role of active information is central to achieving this heterogeneous population structure.

If you're wondering why Chris Olah, the cofounder of AI company Anthropic, was sitting on the stage with Pope Leo today as the pontiff unveiled his new encyclical on AI, well ALLOW ME TO EXPLAIN. religionnews.com/2026/05/22/w...
Inside the unlikely Vatican-Anthropic relationship that's reshaping the AI ethics debate
(RNS) — Pope Leo XIV's new encyclical on AI is set to be released Monday (May 25), with Chris Olah, a co-founder of Anthropic, at his side.

"The culture of power and the civilization of love."
It's a great document. Not just as it regards AI, but its indictment of the broader political economy and world order. Struck by how much of it is so obviously in direct opposition to US policy.
The reason people like the Pope’s AI missive is because there is simply no other institution has taken the side of humanity in the humanities sense. I’m not Catholic, but I am a human who cares about the human mind and the poetics Catholics call a soul.

Only in the 1960s were the terms "prokaryote" and "eukaryote" formalized! As originally defined, eukaryotes had complex architectures, prokaryotes did not.

You ask AI, you put its plan into action, and then you realize. Its optimistic style misled you. It didn't have the required context, it wasn't provided the precise goals, it created incorrect deductions and assumptions.
