Over a decade ago, @FiveThirtyEight published a clever methodology for estimating someone's age based on their first name. I turned it into an interactive tool, the Name Age Calculator. Type in "Jennifer" and discover when that name peaked in 140 years of Social Security data (spoiler: 1970s babies). It went semi-viral and got picked up by major outlets. I've kept it running all these years because people genuinely enjoy it. It's one of those simple projects that reminds me why I love building things: when data tells an interesting story, people want to engage with it. Try it out: name-age-calculator.randalol… Drop a comment with the most surprising name age you discover. I'm curious what you'll find. #DataScience #dataviz #DataAnalysis

Why do you think you've never had smallpox? And you don't even know anyone who has had it? I'll give you a clue : it's because of vaccines

This is an astonishingly bad piece of work. A case study in bias. Starts off by using Wakefield fraudulent, retracted paper as its very basis. Oh and he's an author on this too! This is an advocacy document. An opinion piece. Not research. Not science. Trash.
🚨BREAKING — The Most Comprehensive Analysis Ever Conducted on the Causes of Autism Finds Vaccination Is the DOMINANT Risk Factor After decades of censorship and denial, the McCullough Foundation’s Landmark Report of over 300 studies finally delivers the verdict: Autism’s rise is multifactorial—but vaccination is the MOST significant, preventable driver. We found potential determinants of new-onset autism before age 9 to include: 👵Older parents (>35 years mother, >40 years father) 👶Premature delivery (<37 weeks) 🧬 Common genetic variants 🧩 Siblings with autism 🔥 Maternal immune activation 💊 In utero drug exposure ☣️ Environmental toxicants 🦠 Gut–brain axis alterations 💉 And combination routine childhood vaccination Of 136 studies evaluating vaccines or their components: ➡️ 107 (79%) found evidence consistent with a vaccine–autism link ➡️ 29 claimed “no association,” yet lacked truly unvaccinated controls ➡️ 12 studies comparing fully vaccinated vs. unvaccinated children found every time that the unvaccinated had far better overall health and dramatically lower autism risk. Biologic mechanisms converged on shared pathways—immune dysregulation, mitochondrial dysfunction, and neuroinflammation—triggered by clustered and early-timed vaccination during critical windows of brain development. By evaluating all known risk factors side by side, this analysis uniquely clarifies the relative contribution of vaccination compared to genetic and environmental domains. No prior review has attempted this integrative scope without excluding positive vaccine-association studies or unvaccinated controls—an essential step in determining whether vaccines truly play a role in autism risk, and if so, how significant that role is within the broader causal landscape. Our report represents a major breakthrough through the iron grip of censorship imposed by the Bio-Pharmaceutical Complex on the issue of vaccination and autism. It also marks Dr. Andrew Wakefield’s first major return to the scientific literature in years—after enduring years of irrational attacks from the vaccine cartel. Thanks to the tireless work of the McCullough Foundation team: Nicolas Hulscher, MPH, John S. Leake, MA, Simon Troupe, MPH, Claire Rogers, MSPAS, PA-C, Kirstin Cosgrove, BM, CCRA, M. Nathaniel Mead, MSc, PhD, Bre Craven, PA-C, Mila Radetich, Andrew Wakefield, MBBS, and Peter A. McCullough, MD, MPH — and support from the Bia-Echo Foundation — this historic effort was made possible. CONCLUSION ⬇️ The totality of evidence supports a multifactorial model of ASD in which genetic predisposition, neuroimmune biology, environmental toxicants, perinatal stressors, and iatrogenic exposures converge to produce the phenotype of a post-encephalitic state. Combination and early-timed routine childhood vaccination constitutes the most significant modifiable risk factor for ASD, supported by convergent mechanistic, clinical, and epidemiologic findings, and characterized by intensified use, the clustering of multiple doses during critical neurodevelopmental windows, and the lack of research on the cumulative safety of the full pediatric schedule.

Today I saw an inappropriate AI-generated video of myself. I really loathe that this is what women on the internet have to deal with now. Just so you know, if you ask AI to make sexual videos of people and distribute them online, I think you are absolutely foul.

A massive study on the effects of social class tested 35 hypotheses in 4 countries (N = 33,536). Only 50% of prior findings replicated. Hypotheses based on differences between social class contexts in terms of constraints, uncertainty and status were well supported across countries and measures. Hypotheses based on models positing social class differences in psychological orientations towards ‘the self’ versus ‘others and the environment’ received less support. In short, the social psychology literature on social class did not replicate. The hypotheses about class from other fields largely held up. nature.com/articles/s41562-0…

The American Psychological Association is deeply concerned about the Administration’s recent announcement on #autism. Promoting unsupported scientific theories risks fueling stigma, undermines public trust and distracts from real scientific progress.
