It must be very hard to publish null results
Publication practices in the social sciences act as a filter that favors statistically significant results over null findings. While the problem of selection on significance (SoS) is well-known in theory, it has been difficult to measure its scope empirically, and it has been challenging to determine how selection varies across contexts. In this article, we use large language models to extract granular and validated data on about 100,000 articles published in over 150 political science journals from 2010 to 2024. We show that fewer than 2% of articles that rely on statistical methods report null-only findings in their abstracts, while over 90% of papers highlight significant results. To put these findings in perspective, we develop and calibrate a simple model of publication bias. Across a range of plausible assumptions, we find that statistically significant results are estimated to be one to two orders of magnitude more likely to enter the published record than null results. Leveraging metadata extracted from individual articles, we show that the pattern of strong SoS holds across subfields, journals, methods, and time periods. However, a few factors such as pre-registration and randomized experiments correlate with greater acceptance of null results. We conclude by discussing implications for the field and the potential of our new dataset for investigating other questions about political science.

I have a new paper. We look at ~all stats articles in political science post-2010 & show that 94% have abstracts that claim to reject a null. Only 2% present only null results. This is hard to explain unless the research process has a filter that only lets rejections through.

In January 2017, the African Union noticed that its servers were unusually busy for two hours overnight, when the offices were empty. An investigation would uncover that the AU's confidential data was being siphoned off every night and sent more than 8,000km away, to Shanghai.

Statement from Michael and Susan Pretti
Parents of Alex Jeffrey Pretti
"We are heartbroken but also very angry.
Alex was a kindhearted soul who cared deeply for his family and friends and also the American veterans whom he cared for as an
ICU nurse at the Minneapolis VA hospital. Alex wanted to make a difference in this world. Unfortunately, he will not be with us to see his impact.
I do not throw around the 'hero' term lightly. However, his last thought and act was to protect a woman. The sickening lies told about our son by the administration are reprehensible and disgusting. Alex is clearly not holding a gun when attacked by Trump's murdering and cowardly ICE thugs. He had his phone in his right hand and his empty left hand is raised above his head while trying to protect the woman ICE just pushed down, all while being pepper sprayed.
Please get the truth out about our son. He was a good man. Thank you.

          WASHINGTON —  January 22, 2026 — The U.S. Department of Health and Human Services and the U.S. Department of State today announced the United States’ completion of its withdrawal from the World Health Organization (WHO) due to the organization's mishandling of the COVID-19 pandemic that arose out of Wuhan, China, its failure to adopt urgently needed reforms, and its inability to demonstrate independence from the inappropriate political influence of WHO member states.Health and Human Services Secretary Robert F. Kennedy, Jr. and Secretary of State Marco Rubio issued a joint statement on the termination of U.S. membership in the WHO.President Trump on January 20, 2025, announced the U.S. plan to leave the WHO. During the yearlong process, the U.S. stopped funding WHO, withdrew all personnel from WHO, and began pivoting activities previously conducted with WHO to direct bilateral engagements with other countries and organizations. With the exit from WHO, the U.S. will be coordinating with WHO solely in a limited fashion to effectuate withdrawal.  The WHO delayed declaring a global public health emergency and a pandemic during the early stages of COVID-19, costing the world critical weeks as the virus spread. During that period, WHO leadership echoed and praised China's response despite evidence of early underreporting, suppression of information and delays in confirming human-to-human transmission. The organization also downplayed asymptomatic transmission risks and failed to promptly acknowledge airborne spread.After the pandemic, the WHO did not adopt meaningful reforms to address political influence, governance weaknesses or poor coordination, reinforcing concerns that politics took priority over rapid, independent public health action and eroding global trust.

Scientists are often encouraged to remain “neutral” on social and political issues as if the conditions under which science is conducted, funded, and applied are somehow separate from politics and the state of the world around us. They aren’t.
