The Social Laser theory describes society by borrowing the inner workings of a laser. People, like atoms in a crystal, absorb streams of information and become charged by it. When the number of those charged with a single idea outweighs the indifferent, even a weak signal (a post, a call to action) makes everyone act as one. This is how directed collective action emerges instead of cacophonous noise.
Practical takeaway: if we measure the intensity of public attention (analogous to radiation intensity), we can spot the approach of a tipping point from disorder to unity. Analysts call this sharp shifts — the moment when pent-up energy erupts like an avalanche. Such a tool would allow us to foresee mass movements before they start.
The first laser, built by Townes and colleagues, used a ruby and a flashlamp. Today its descendants scan barcodes and cut metal, while the very concept of coherent amplification helps model social explosions.
The model evokes psychohistory from Isaac Asimov's Foundation series, where math predicted the future of civilizations.
