This section serves as a **centralized reference hub** for key academic studies related to various fields such as **social psychology, public policy, behavioral economics, and more**. Each study is categorized for easy navigation and presented in a **collapsible format** to maintain a clean layout.

7 -=== How to Use This Repository ===
5 + 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 conclusions in most cases. That's because I havent gotten to going through and pointing out the reasons I put all of them in here.

8 + There is often an underlying hypocrisy or double standar, 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:

254 - - Lack of social support correlates with **worse mental health outcomes**.
230 + - **African populations harbor the greatest genetic diversity**, confirming an out-of-Africa dispersal model.

528 -This study reviews **genome-wide association study (GWAS) findings on intelligence**, demonstrating a **strong correlation between polygenic intelligence scores and national IQ levels**. The research highlights how **genetic selection may explain population-level cognitive differences beyond genetic drift effects**. Intelligence-linked alleles showed **higher variability across populations than height-related alleles**, suggesting stronger selection pressures.
537 +This study examines **how human genetic adaptation has unfolded over 14,000 years**, using a **large dataset of ancient DNA**. It highlights **strong selection on immune function, metabolism, and cognitive traits**, revealing **hundreds of loci affected by directional selection**. The findings emphasize **the power of ancient DNA in tracking human evolution and adaptation**.##

1478 +Subgroup Analysis:
1479 +
1480 +Males exhibited higher rates of cannabis use, but females reported stronger mental health impacts.
1481 +Individuals with pre-existing anxiety disorders were more likely to report problematic cannabis use.
1482 +Other Significant Data Points:
1483 +
1484 +Frequent cannabis users showed a 23% higher likelihood of developing anxiety symptoms.
1485 +Co-occurring substance use (e.g., alcohol) exacerbated negative psychological effects.

1493 +Early cannabis initiation (before age 16) was associated with greater mental health risks.
1494 +College-aged users reported more impairments in daily functioning due to cannabis use.
1495 +Specific Case Analysis:
1496 +
1497 +Participants with a history of childhood trauma were twice as likely to develop problematic cannabis use.
