Research at a Glance
Edit
Welcome to the Research at a Glance repository. This section serves as a centralized reference hub for key academic studies related to various important Racial themes. Each study is categorized for easy navigation and presented in a collapsible format to maintain a clean layout. I wanted to make this for a couple of reasons. Number one is organization. There are a ton of useful studies out there that expose the truth, sometimes inadvertently. You'll notice that in this initial draft the summaries are often woke and reflect the bias of the AI writing them as well as the researchers politically correct conclusion in most cases. That's because I haven't gotten to going through and pointing out the reasons I put all of them in here.
There is often an underlying hypocrisy or double standard, saying the quiet part out loud, or conclusions that are so much of an antithesis to what the data shows that made me want to include it. At least, thats the idea for once its polished. I have about 150 more studies to upload, so it will be a few weeks before I get through it all. Until such time, feel free to search for them yourself and edit in what you find, or add your own studies. If you like you can do it manually, or if you'd rather go the route I did, just rename the study to its doi number and feed the study into an AI and tell them to summarize the study using the following format:
- Click on a category in the Table of Contents to browse studies related to that topic.
- Click on a study title to expand its details, including key findings, critique, and relevance.
- Use the search function (Ctrl + F or XWiki's built-in search) to quickly find specific topics or authors.
- If needed, you can export this page as PDF or print-friendly format, and all studies will automatically expand for readability.
- You'll also find a download link to the original full study in pdf form at the bottom of the collapsible block.

DOI: [10.1016/j.intell.2014.05.012](https://doi.org/10.1016/j.intell.2014.05.012)
Subject Matter: *Cognitive Decline, Intelligence, Dysgenics*
- General Observations:
- The study examines reaction time data from 13 age-matched studies spanning 1884–2004.
- Results suggest an estimated decline of 13.35 IQ points over this period.
2. Subgroup Analysis:
- The study found slower reaction times in modern populations compared to Victorian-era individuals.
- Data from Western countries (US, UK, Canada, Australia, Finland) were analyzed.
3. Other Significant Data Points:
- The estimated dysgenic rate is 1.21 IQ points lost per decade.
- Meta-regression analysis confirmed a steady secular trend in slowing reaction time.
- Primary Observations:
- Supports the hypothesis of intelligence decline due to genetic and environmental factors.
- Reaction time, a biomarker for cognitive ability, has slowed significantly over time.
2. Subgroup Trends:
- A stronger correlation between slower reaction time and lower general intelligence (g).
- Flynn effect (IQ gains) does not contradict this finding, as reaction time is a biological, not environmental, measure.
3. Specific Case Analysis:
- Cross-national comparisons indicate a global trend in slower reaction times.
- Factors like modern neurotoxin exposure and reduced selective pressure for intelligence may contribute.
- Strengths of the Study:
- Comprehensive meta-analysis covering over a century of reaction time data.

Subject Matter: *Health Disparities, Racial Bias, Medical Treatment*
- General Observations:
- Study analyzed racial disparities in pain perception and treatment recommendations.
- Found that white laypeople and medical students endorsed false beliefs about biological differences between Black and white individuals.
2. Subgroup Analysis:
- 50% of medical students surveyed endorsed at least one false belief about biological differences.
- Participants who held these false beliefs were more likely to underestimate Black patients’ pain levels.
3. Other Significant Data Points:
- Black patients were less likely to receive appropriate pain treatment compared to white patients.
- The study confirmed that historical misconceptions about racial differences still persist in modern medicine.
- Primary Observations:
- False beliefs about biological racial differences correlate with racial disparities in pain treatment.
