Does social media harm everyone?
No. But it harms *most* adolescents.
However, not all platforms are harmful.
An analysis of 44,211 diaries from 479 adolescents over 100 days finds that 60% of adolescents experienced small, negative effects of social media

How do large language models interpret words relating to probability like “unlikely,” “probably,” or “almost certain"?
The below shows what happens when we compare judgements from different models to a benchmark dataset of human judgments (data from: github.com/zonination/p...).

Diederik Stapel was a massive watershed moment in psychology.
However, he was -- and let's be slightly glib here -- some guy from The Netherlands who wrote social psychology papers.
The full accounting of the Eysenck case is approx, at minimum, TWO STAPELS.

😯 I recently came across a sobering paper on here: among 16,649 hypothesis tests reported in political science, the median test has only about 10% power to detect the consensus effect size reported in the literature. Fewer than one in ten tests reach the conventional 80% power threshold.

1. LLM-generated code tries to run code from online software packages. Which is normal but
2. The packages don’t exist. Which would normally cause an error but
3. Nefarious people have made malware under the package names that LLMs make up most often. So
4. Now the LLM code points to malware.

LLMs hallucinating nonexistent software packages with plausible names leads to a new malware vulnerability: "slopsquatting."
