Neurohistory

An emerging interdisciplinary field that seeks to understand historical change through the lens of the human brain’s evolving biology, cognitive biases, and emotional responses. It asks: How did the hardwired need for status, our fear of the “other,” or the brain’s response to environmental scarcity shape the rise of feudalism, religious movements, or economic systems? It grounds the why of history in the how of the human neural processor.
Example: “A neurohistory of the Crusades wouldn’t just cite theology; it’d examine how the promise of salvation hijacked the brain’s reward system, how the scarcity of land triggered territorial aggression circuits, and how the vivid, fear-based imagery of preaching activated amygdalas across Europe, mobilizing masses in ways abstract political arguments never could.”

Neurohistory Theory

An emerging, interdisciplinary theoretical framework that argues the course of human history cannot be understood without studying the evolutionary biology and cognitive wiring of the human brain. It posits that historical forces—wars, religious movements, economic systems—are downstream effects of deep-seated neural drives: our craving for status, our tribalism, our fear responses to scarcity, and our cognitive biases. The theory seeks to explain why certain historical patterns recur by grounding them in the non-negotiable hardware of the human mind, treating culture as software running on ancient, sometimes buggy, cerebral processors.
*Example: "A Neurohistory Theory analysis of the 20th century wouldn't start with treaties, but with the brain's dopaminergic reward system. It would argue that the rise of fascism and consumerism are two sides of the same coin: both are ultra-efficient at hijacking our primal neural circuits for hierarchy and acquisition. The propaganda poster and the billboard, according to this theory, are just different stimuli for the same ancient mammalian brain."*

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
