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. 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 feed the study into an AI and tell them to summarize the study using the following format:

1390 +Subgroup Analysis:
1391 +
1392 +Males exhibited higher rates of cannabis use, but females reported stronger mental health impacts.
1393 +Individuals with pre-existing anxiety disorders were more likely to report problematic cannabis use.
1394 +Other Significant Data Points:
1395 +
1396 +Frequent cannabis users showed a 23% higher likelihood of developing anxiety symptoms.
1397 +Co-occurring substance use (e.g., alcohol) exacerbated negative psychological effects.
1398 +Findings
1399 +Primary Observations:
1400 +
1401 +Cannabis use was linked to higher depressive and anxiety symptoms, particularly in frequent users.
1402 +Self-medication patterns emerged among those with pre-existing mental health conditions.
1403 +Subgroup Trends:
1404 +
1405 +Early cannabis initiation (before age 16) was associated with greater mental health risks.
1406 +College-aged users reported more impairments in daily functioning due to cannabis use.
1407 +Specific Case Analysis:
1408 +
1409 +Participants with a history of childhood trauma were twice as likely to develop problematic cannabis use.

1432 +Summary of Research Study
1433 +This study examines the relationship between cannabis use and mental health symptoms in young adults, focusing on depressive and anxiety-related outcomes. Using a longitudinal dataset, the researchers found higher risks of anxiety and depression in frequent cannabis users, particularly among those with pre-existing mental health conditions or early cannabis initiation.

1456 +1. **General Observations:**
1457 + - The study examines reaction time data from **13 age-matched studies** spanning **1884–2004**.
1458 + - Results suggest an estimated **decline of 13.35 IQ points** over this period.
1459 +
1460 +2. **Subgroup Analysis:**
1461 + - The study found **slower reaction times in modern populations** compared to Victorian-era individuals.
1462 + - Data from **Western countries (US, UK, Canada, Australia, Finland)** were analyzed.
1463 +
1464 +3. **Other Significant Data Points:**
1465 + - The estimated **dysgenic rate is 1.21 IQ points lost per decade**.
1466 + - Meta-regression analysis confirmed a **steady secular trend in slowing reaction time**.
