Will Nonbelievers Really Believe Anything?

10 min • 1,246 words • 867 comments • 174 likes • podcast
Scott Alexander investigates whether non-religious people are more prone to believing conspiracy theories, finding a U-shaped relationship between religiosity and skepticism. Longer summary
Scott Alexander examines the claim that non-religious people are more likely to believe in conspiracy theories and woo. He analyzes various studies on beliefs in UFOs, Bigfoot, and astrology across different religious groups. The results show a more nuanced picture: both strongly religious people and outright atheists are generally less likely to believe in these theories, while those in the middle (weakly religious or agnostic) are more susceptible. Scott discusses possible explanations for this pattern, including intellectual coherence and closed-mindedness. He concludes that the relationship between religiosity and belief in conspiracy theories is more complex than commonly assumed. Shorter summary

Sleep Support: An Individual Randomized Controlled Trial

10 min • 1,268 words • 88 comments • podcast
Scott Alexander conducts a personal randomized controlled trial of a sleep supplement, finding no significant effect over placebo, but gains insights into his sleep patterns. Longer summary
Scott Alexander conducts a personal randomized controlled trial to test the effectiveness of a sleep supplement called Sleep Support. Initially, he experiences a dramatic improvement in his sleep patterns, but decides to rigorously test this effect. He designs an experiment using placebo pills and blind administration over 24 nights. Surprisingly, the results show no significant difference between the Sleep Support and placebo nights in terms of sleep duration, wake-up time, or subjective measures. Scott concludes that his initial perceived improvement was likely due to the placebo effect and the act of not checking the clock upon waking. Despite the supplement not outperforming placebo, Scott considers the experiment a success as it led to improved sleep habits. Shorter summary

Assortative Mating And Autism

9 min • 1,147 words • 108 comments • podcast
Scott Alexander analyzes survey data to investigate whether assortative mating among highly analytical people increases autism risk in their children, finding no significant evidence for this hypothesis. Longer summary
Scott Alexander investigates whether assortative mating among highly analytical people in Silicon Valley increases the risk of autism in their children. He uses data from the 2020 Slate Star Codex survey, which included 8,043 respondents from highly analytical backgrounds. The study found that while the sample had higher rates of autism (4-8%) than the general population (2.5-5%), there was no significant increase in autism rates among children of couples where both partners were highly analytical. The autism rate for children in the sample was 3.7-5.2%, with only 0.6% having severe autism. Scott concludes that while the study has limitations, it provides evidence against strong versions of the assortative mating hypothesis for autism risk. Shorter summary

Followup On The Baumol Effect: Thanks, O Baumol

15 min • 1,940 words • 186 comments • podcast
Scott Alexander follows up on his critique of a book about the Baumol effect, presenting data that challenges the book's claims about rising wages driving cost increases in education and healthcare. Longer summary
Scott Alexander follows up on his review of Tabarrok and Helland's book about the Baumol effect and rising costs in education and healthcare. He expresses disappointment with Tabarrok's response to his critique and further explores the issues. Scott presents data showing that wages in high-productivity sectors and for doctors and teachers have not risen as much as claimed, which challenges the book's central thesis. He also clarifies his understanding of how the Baumol effect can make things less affordable for individuals even if not for society as a whole. The post analyzes various data sources and graphs to support these points, maintaining a critical stance towards the original book's arguments. Shorter summary

Age Gaps And Birth Order Effects

13 min • 1,636 words • 191 comments • podcast
Scott Alexander analyzes birth order effects in SSC readers, finding strong effects for sibling age gaps of 1-7 years, with a significant drop-off after 7 years. Longer summary
Scott Alexander investigates birth order effects using data from the 2019 Slate Star Codex survey. He finds that firstborns are overrepresented among SSC readers, replicating previous findings. The study focuses on how age gaps between siblings affect this birth order effect. Results show strong effects for age gaps of 1-7 years, with a dramatic decrease for gaps larger than 7 years. Scott discusses possible explanations for these findings, including intra-family competition and parental investment hypotheses. He notes that the results don't seem consistent with some other proposed mechanisms like maternal antibodies or vitamin deficiencies. The post ends with a call for further replication and expansion of these results. Shorter summary

Kernel Of Doubt: Testing Math Preference Vs. Corn-Eating Style

10 min • 1,212 words • 98 comments • podcast
Scott Alexander tests the claim that mathematicians' preference for algebra or analysis predicts their corn-eating style, finding no significant correlation in a survey of over 2,600 respondents. Longer summary
Scott Alexander investigates a claim made by Ben Tilly that mathematicians' preference for algebra or analysis predicts how they eat corn (in rows or spirals). Scott included questions about math preference and corn-eating style in his 2019 Slate Star Codex reader survey. Analyzing 2,683 responses, including a subset of PhD mathematicians, he found no significant correlation between math preference and corn-eating style, contradicting Tilly's observation. Scott suggests the original claim might be due to the power of suggestion or selective memory. He also explores demographic factors influencing corn-eating styles, finding some cultural differences but no clear explanation for the variability. Shorter summary

Working With Google Trends

14 min • 1,706 words • 52 comments • podcast
Scott Alexander investigates the complexities of using Google Trends for mental health research, proposing methods to improve accuracy and interpretation of search data. Longer summary
Scott Alexander explores the challenges and nuances of using Google Trends for research, focusing on mental health-related searches. He demonstrates how individual keywords can be misleading and suggests averaging multiple related terms. Scott introduces a two-factor theory: one representing students' intellectual interest in mental health, which is declining, and another representing people with mental health issues, which is increasing. He discusses potential issues like temporal autocorrelation and provides tips for using Google Trends effectively, including the importance of considering school-related search patterns and the lack of need to adjust for general intellectual decline on the Internet.

Nighttime Ventilation Survey Results

5 min • 616 words • 26 comments • podcast
Scott Alexander reports on a survey about nighttime ventilation interventions, finding modest overall improvements but some individual success stories. Longer summary
Scott Alexander presents the results of a survey on nighttime ventilation conducted after his previous post on carbon dioxide levels. The survey, with 129 participants, explored various interventions to improve sleep quality by reducing CO2 levels. While the overall results were modest, with an average improvement of 1.4 on a 0-5 scale, some participants reported significant benefits. The most common intervention was sleeping with an open window. Despite the underwhelming results, most participants planned to continue their interventions. Scott concludes that the results are essentially negative, both for nighttime ventilation and for the reliability of informal blog surveys in producing confident data. Shorter summary

Polyamory Is Not Polygyny

8 min • 968 words • 791 comments • podcast
Scott Alexander uses survey data to challenge claims that polyamory leads to a few men monopolizing women, showing these criticisms don't match reality in practice. Longer summary
Scott Alexander addresses criticisms of polyamory from both conservative and pickup artist perspectives, which claim it leads to a few high-status men monopolizing women. Using survey data from the Less Wrong community, he shows these criticisms don't match reality. The data suggests poly women have more partners on average than poly men, and poly men are less likely to be single than monogamous men. Scott acknowledges potential biases in the data but argues it still contradicts the critics' theories. He invites critics to suggest what data would convince them in future surveys. Shorter summary

Heuristics Work Until They Don’t

9 min • 1,067 words • 350 comments • podcast
Scott Alexander warns against forming strong heuristics based on limited data, using examples from AI research, elections, and campaign strategies to illustrate the pitfalls of this approach. Longer summary
Scott Alexander discusses the dangers of forming strong heuristics based on limited data points. He presents three examples: AI research progress, election predictions, and campaign strategies. In each case, he shows how people formed confident heuristics after observing patterns in just one or two instances, only to be surprised when these heuristics failed. The post argues against treating life events as moral parables and instead advocates for viewing them as individual data points that may not necessarily generalize. Scott uses a mix of statistical reasoning, historical examples, and cultural references to illustrate his points. Shorter summary

Republicans Are Douchebags

6 min • 724 words • 276 comments • podcast
Scott Alexander examines the correlation between names considered 'douchebag' names and Republican political affiliation, presenting humorous hypotheses to explain the findings. Longer summary
Scott Alexander humorously explores the correlation between names perceived as 'douchebag' names and political affiliation. He compares two lists of names considered 'douchebag' names from internet sources with data on political affiliation by name. The analysis reveals that names considered 'douchebag' names are disproportionately associated with Republican voters. Scott presents three hypotheses to explain this correlation: douchebags are disproportionately Republican, parents who choose these names are disproportionately Republican, or 'douchebag' is a tribally-coded slur. The post maintains a satirical tone throughout, starting with a deliberately provocative title. Shorter summary
