Why social media feeds favor enraging content
Social media isn't broken; it is working exactly as intended. Engagement tracking proves that users interact far more with content that enrages them, so the…

Why AI systems struggle to explain their decisions
We built digital oracles that refuse to show their work. Modern neural networks process variables through so many hidden layers that even the original…
