A parent details their year-long experience with Alpha School in Austin, examining how this innovative program achieves accelerated learning through a combination of technology, personalized instruction, and incentive systems. Longer summary

This extensive review details the author's year-long experience with Alpha School, an innovative educational program in Austin that claims to achieve accelerated learning through a '2-hour learning' platform, analyzing its history, methods, effectiveness, and potential for scaling.

Scott Alexander argues that pseudoaddiction is a real and important concept, despite being widely denounced as pharma propaganda in the context of the opioid crisis. Longer summary

Scott Alexander argues that pseudoaddiction - the concept that some drug-seeking behaviors are due to undertreated pain rather than addiction - is real and important, despite being widely denounced as pharma propaganda. He presents several case studies from his own practice where patients exhibited 'drug-seeking behavior' for legitimate medical reasons.
