Kanji Amnesia: Why I Remember the Meaning But Not the Writing

The author mastered kanji by first learning their meanings and writing, then pronunciation. Years later, he can't handwrite most kanji. This 'Kanji Amnesia' is common in Japan and China. He explores the brain's separate processes for reading and writing, and his aphantasia (lack of mental imagery) adds to the mystery. Cognitive science suggests this stems from the brain's use of both verbatim and gist memory traces. Reading involves recognizing the gist, while writing activates motor memory of strokes – two distinct skills.

The 1%, Climate Change, and Trillions in Damages: Is Legal Liability on the Horizon?

A new modeling study in Nature Climate Change reveals that the wealthiest 10% of the global population are responsible for two-thirds of global warming since 1990. The top 1% alone account for one-fifth, not only due to higher energy consumption but also through investments in high-emission sectors like fossil fuels. The study highlights the disproportionate contribution of the wealthy to extreme weather events, particularly in poorer nations, with the richest 1% contributing 26 times more to extreme heat globally and 17 times more to Amazonian droughts than the average person. This research bolsters the argument for climate liability, with the authors estimating Chevron's contribution to extreme heat damage at up to $3.6 trillion, suggesting the scientific case for holding specific companies legally accountable is now closed.

Global Scam Call Center Metastasis: A Worldwide Criminal Expansion

The UN warns that global scam call centers are spreading like a cancer, with criminal syndicates expanding and operating worldwide. Crackdowns in East and Southeast Asia have led to operations shifting to more permissive regions, including Africa, South Asia, parts of the Pacific Islands, and even links to money laundering and recruitment in Europe and North America. These groups leverage local language skills to broaden their victim pool and drastically increase profits. The report estimates annual earnings between $27.4 billion and $36.5 billion, targeting regions with weak governance. Law enforcement actions have resulted in arrests of foreign nationals involved in fraud and cybercrime; for example, 77 suspects, including 22 Chinese nationals, were arrested in Zambia in April 2024. While reliable data is limited in South America, Asian criminal groups are expanding online fraud and gambling infrastructure and forging money laundering partnerships with local drug cartels. In Europe, Georgia and Turkey have emerged as cyberfraud hotspots. Additionally, criminal syndicates establish seemingly legitimate businesses (hotels, casinos, travel agencies) in Pacific island nations to conceal illegal online gambling, drug and human trafficking, migrant smuggling, and money laundering. The UN recommends strengthening regulatory frameworks and equipping authorities with the resources to combat these crimes.
