--**Author(s):** *Thomas J. Bouchard Jr.*
--**Title:** *"The Wilson Effect: The Increase in Heritability of IQ With Age"*
--**DOI:** [10.1017/thg.2013.54](https://doi.org/10.1017/thg.2013.54)
--**Subject Matter:** *Intelligence, Heritability, Developmental Psychology*
--
  {{expandable summary="📊 Key Statistics"}}
--1. **General Observations:**
--   - The study documents how the **heritability of IQ increases with age**, reaching an asymptote at **0.80 by adulthood**.
--   - Analysis is based on **longitudinal twin and adoption studies**.
--
--2. **Subgroup Analysis:**
--   - Shared environmental influence on IQ **declines with age**, reaching **0.10 in adulthood**.
--   - Monozygotic twins show **increasing genetic similarity in IQ over time**, while dizygotic twins become **less concordant**.
--
--3. **Other Significant Data Points:**
--   - Data from the **Louisville Longitudinal Twin Study and cross-national twin samples** support findings.
--   - IQ stability over time is **influenced more by genetics than by shared environmental factors**.
++- Survey of **102 intelligence experts**
++- **90% from Western countries**, **83% male**
++- **54% left-liberal**, **24% conservative**
++- **50/50 split** on genetic vs environmental causes of Black-White IQ gap
  {{/expandable}}
  {{expandable summary="🔬 Findings"}}
--1. **Primary Observations:**
--   - Intelligence heritability **strengthens throughout development**, contrary to early environmental models.
--   - Shared environmental effects **decrease by late adolescence**, emphasizing **genetic influence in adulthood**.
--
--2. **Subgroup Trends:**
--   - Studies from **Scotland, Netherlands, and the US** show **consistent patterns of increasing heritability with age**.
--   - Findings hold across **varied socio-economic and educational backgrounds**.
--
--3. **Specific Case Analysis:**
--   - Longitudinal adoption studies show **declining impact of adoptive parental influence on IQ** as children age.
--   - Cross-sectional twin data confirm **higher IQ correlations for monozygotic twins in adulthood**.
++- Support for **g-factor theory**
++- Agreement on **heritability of intelligence**
++- Political lean: left = environmental, right = genetic causes

--{{expandable summary="📝 Critique & Observations"}}
--1. **Strengths of the Study:**
--   - **Robust dataset covering multiple twin and adoption studies over decades**.
--   - **Clear, replicable trend** demonstrating the increasing role of genetics in intelligence.
--
--2. **Limitations of the Study:**
--   - Findings apply primarily to **Western industrialized nations**, limiting generalizability.
--   - **Lack of neurobiological mechanisms** explaining how genes express their influence over time.
--
--3. **Suggestions for Improvement:**
--   - Future research should investigate **gene-environment interactions in cognitive aging**.
--   - Examine **heritability trends in non-Western populations** to determine cross-cultural consistency.
++{{expandable summary="📝 Critique"}}
++- Largest expert survey on intelligence
++- **Western-only sample**, possible **self-selection bias**
  {{/expandable}}
--{{expandable summary="📌 Relevance to Subproject"}}
--- Provides **strong evidence for the genetic basis of intelligence**.
--- Highlights the **diminishing role of shared environment in cognitive development**.
--- Supports research on **cognitive aging and heritability across the lifespan**.

++- Shows **ideological divide** in science
++- Highlights **media vs expert disconnect**
  {{/expandable}}
--{{expandable summary="🔍 Suggestions for Further Exploration"}}
--1. Investigate **neurogenetic pathways underlying IQ development**.
--2. Examine **how education and socioeconomic factors interact with genetic IQ influences**.
--3. Study **heritability trends in aging populations and cognitive decline**.
