AI Models Find 2020s Most Correlated with 1920s Since 1950s: Dr. Williams Says That This Should Sound the Alarm

ChatGPT

To determine which year between 1950 and 2025 is most correlated with the 1920s, we first need to define clear criteria for comparison. Since “correlation” implies a relationship across multiple variables, this analysis will rest on quantitative indicators that reflect the socioeconomic, political, cultural, and technological conditions of each era.

🔧 Methodological Framework for Historical Correlation Analysis

I. Define Core Domains of Comparison

We'll select variables from five core domains that capture the “spirit” or structural dynamics of a given year:

1. Economic Conditions

   • GDP growth rate

   • Income inequality (Gini coefficient or top 1% share)

   • Stock market volatility or bubble activity

   • Speculative investment trends

2. Social and Political Climate

   • Nativist or anti-immigration sentiment

   • Political polarization index

   • Frequency of mass protest or civil unrest

   • Media censorship or propaganda prevalence

3. Technological & Cultural Transformation

   • Dominant communication technology (radio in 1920s, social media in 2020s)

   • Cultural liberalism/conservatism tension

   • Celebrity or influencer economy intensity

4. Public Health and Risk Perception

   • Mortality and morbidity shock events (e.g., pandemics)

   • Government response to public health crises

   • Public trust in science/medicine

5. Racial and Ethnic Conflict / Segregationism

   • Legal or de facto racial segregation

   • Rise of supremacist groups

   • Institutional exclusion of racial minorities (voting, education, housing)

II. Operationalize the 1920s as a Benchmark Vector

Construct a profile for the 1920s using scaled or binary indicators across the domains above:

Variable - 1920s Value (normalized scale 0–1 or categorical)

Income Inequality - 0.9 (very high)

Nativism - 1.0 (Immigration Act of 1924)

Stock Speculation - 1.0 (peak speculative bubble)

Mass Protest - 0.3 (labor unrest, but not dominant)

Technological Change - 0.8 (radio, mass car ownership)

Celebrity Culture - 0.7 (silent film stars, sports heroes)

Public Health Shock - 0.6 (post-1918 flu effects)

Racial Conflict - 1.0 (KKK peak, race massacres, segregation laws)

This becomes our target vector.

III. Construct Yearly Profiles from 1950 to 2025

For each year:

• Score that year on each of the above variables (using historical datasets, archives, and secondary literature).

• Normalize values for comparability.

• Form a vector of scores for each year.

IV. Statistical Comparison

• Use Pearson correlation coefficient to compute the correlation between each year's vector and the 1920s reference vector.

• The year with the highest correlation coefficient (r) is deemed most historically “rhyming” with the 1920s.

🧪 Results (Simulated Illustration)

Using historical knowledge and available trends, here’s an illustrative subset of years showing their estimated correlation with the 1920s:

Year - Correlation (r) with 1920s

1950 - 0.42

1968 - 0.55

1980 - 0.47

1992 - 0.39

2008 - 0.61

2016 - 0.88

2020 - 0.85

2023 - 0.91

2025 - 0.93 (Highest)

📊 Key Findings

✅ Highest Correlation: 2025

2025 scores highest due to:

• Economic precarity + speculation: housing, crypto, AI bubble

• Resurgence of racial nationalism: Trump 2.0, voter suppression, right-wing courts

• High inequality: billionaire class consolidation

• Nativism: aggressive border and asylum policies

• Public distrust of institutions: science, media, elections

• Technological transformation: generative AI as disruptive as radio/film

• Public health disillusionment: post-COVID backlash, underfunded infrastructure

Close runners-up:

• 2023: Trump’s resurgence, AI boom, post-COVID exhaustion, Dobbs ruling effects

• 2016: Trump’s election, racial tension, meme culture explosion (early digital celebrity populism)

🧠 Discussion

The 1920s and 2025 reflect mirror decades in structural terms:

• Booms built on speculation (radio/stocks vs. AI/crypto)

• Extreme racial tension (Jim Crow resurgence vs. anti-CRT laws)

• Technological acceleration (radio and cinema vs. AI and synthetic media)

• Political extremism (KKK and red scare vs. MAGA and election denial)

• Nativist populism as a backlash to prior liberalization phases

Despite the century between them, both decades illustrate how liberal optimism collides with elite consolidation, cultural fragmentation, and racial scapegoating.

🔍 Limitations and Future Work

• Full implementation would benefit from a numeric historical database for all 76 years.

• Weighting variables could alter rankings (e.g., giving more weight to racial conflict or economic instability).

• Future iterations could use cosine similarity or machine learning classification to identify latent "decade archetypes."

Executive Summary

After establishing five core criteria for comparison—Economic Parallels, Technological Disruption, Social & Cultural Upheaval, Geopolitical Climate, and the "Pre-Crisis" Atmosphere—the analysis concludes that the 2020s (2020-2025) exhibit the strongest and most multifaceted correlation with the 1920s.

While the late 1990s show a strong parallel in terms of a tech-driven economic boom and speculative bubble, the 2020s align more closely across all five criteria, including the crucial post-pandemic context, deep cultural divides, and a fragile geopolitical landscape.

Part 1: Developing the Criteria for Correlation

To compare historical periods, we must define the essential character of the 1920s. It was not a monolithic decade, but it is defined by several powerful, overlapping trends.

The Five Core Criteria:

1. Economic Parallels: The "Roar" and its Instability

   • Post-Crisis Boom: A period of rapid economic expansion and wealth creation following a major global crisis (WWI and the 1918-1920 Spanish Flu pandemic).

   • Consumerism & Credit: A fundamental shift toward a mass consumer economy driven by new products and the widespread adoption of installment buying.

   • Asset Bubbles & Speculation: A frenzy of speculation in new markets (stocks, Florida real estate) accessible to a broader, less experienced public.

   • Wealth Inequality: A dramatic widening of the gap between the rich and the working class.

2. Technological Disruption: The Dawn of a New Era

   • Transformative Technologies Go Mainstream: The rapid, society-altering adoption of revolutionary technologies that changed daily life, work, and entertainment (e.g., the automobile, the radio, the cinema).

   • Infrastructure Build-out: Massive investment in new infrastructure to support these technologies (e.g., road networks, electrical grids, radio towers).

3. Social & Cultural Upheaval: Modernity vs. Tradition

   • Shifting Social Mores: A visible rebellion against Victorian-era norms, especially among the youth (e.g., "Flappers," jazz culture, new attitudes towards sex).

   • Intense Culture Wars: A deep societal clash between modern, urban, secular values and rural, traditional, religious values (e.g., Prohibition, the Scopes "Monkey" Trial, resurgent KKK).

   • Artistic Flourishing: A burst of creative energy and modernism in literature, art, and music (e.g., The Lost Generation, the Harlem Renaissance, Art Deco).

4. Geopolitical Climate: An Anxious Peace

   • Post-War Retrenchment: A retreat from internationalism into isolationism, particularly in the United States, following a devastating global war.

   • Shifting World Order: The old European empires were weakened, and new powers were on the rise.

   • Rise of New Ideologies: A background of simmering political tension and the growth of radical new ideologies (Communism, Fascism) that would define the coming decades.

5. The "Pre-Crisis" Atmosphere: A Party on the Edge

   • This is a meta-criterion based on hindsight. It’s the feeling of a glittering, fast-paced era that is fundamentally unstable and heading towards a major reckoning (The Great Depression and WWII). Does the period in question feel like the "calm before the storm"?

Part 2: Applying the Criteria (1950-2025)

Here, we will score each period against the criteria to determine the best fit.

1950s

• Correlation: Moderate. A post-war (WWII) economic boom with a surge in consumerism (suburban homes, appliances, cars).

• Contrast: The 1950s are often characterized by social conformity, not rebellion. The geopolitical climate was one of intense international engagement (Cold War), the opposite of 1920s isolationism. The economic boom felt more solid and less speculative.

• Correlation Score: Low

1960s

• Correlation: Strong social and cultural upheaval, with youth rebellion and a clash of values.

• Contrast: The upheaval was politically driven (Civil Rights, Vietnam War) rather than purely cultural or economic. The economy was strong but not characterized by the same kind of speculative frenzy.

• Correlation Score: Low-Medium

1970s

• Correlation: Almost zero. This decade was defined by economic malaise (stagflation, oil crisis) and national disillusionment (Vietnam, Watergate). It was the antithesis of the "Roaring Twenties."

• Correlation Score: Very Low

1980s

• Correlation: Some economic parallels with a focus on deregulation, wealth, and a "greed is good" ethos.

• Contrast: The technological shift (personal computer) was still in its early stages and not as universally transformative within the decade. The cultural mood was more conservative than the rebellious 1920s. The geopolitical backdrop was the late Cold War, not post-war isolationism.

• Correlation Score: Medium

Late 1990s (approx. 1995-2000)

This period is a very strong candidate.

• Economic Parallels: Very strong. A post-Cold War boom driven by a new technology (the internet). A massive speculative bubble (Dot-com) with average people investing heavily. Rising wealth inequality.

• Technological Disruption: Very strong. The internet and personal computer became mainstream, fundamentally changing communication and business.

• Contrast: The social and cultural upheaval was less pronounced than in the 1920s. The geopolitical climate was one of unipolar American dominance ("the end of history"), not a tense, multi-polar peace.

• Correlation Score: High

2000s

• The decade was bisected by 9/11 and ended with the 2008 financial crisis. The post-9/11 mood of security anxiety and war is a poor match. The crash of 2008 is a parallel to 1929, making the late 90s the better analog for the decade leading up to the crash.

• Correlation Score: Low

2010s

• Correlation: Post-financial crisis recovery. Technology (social media, smartphones) became completely ubiquitous. Rising political polarization and culture wars intensified.

• Contrast: The economic growth was widely perceived as slow and grinding, not a "roar." The cultural mood was more anxious and fragmented than celebratory.

• Correlation Score: Medium

2020s (2020 - 2025 projection)

This period shows the most striking and comprehensive parallels.

• Economic Parallels (High Correlation): Emerged from a global pandemic (COVID-19) into a bizarre economic environment with massive government stimulus, inflation, and then a boom. Wild speculation in new assets (crypto, meme stocks) by a new generation of retail investors. AI is driving a new wave of productivity hopes and investment. Wealth inequality is at extreme levels.

• Technological Disruption (High Correlation): Artificial Intelligence is being hailed as a transformative technology on the scale of the internet or electricity, poised to reshape all industries. Remote work has permanently altered professional life.

• Social & Cultural Upheaval (High Correlation): Extremely intense culture wars over identity, history, and social values, echoing the modern vs. traditional fights of the 1920s. A palpable sense of social norms rapidly changing.

• Geopolitical Climate (High Correlation): A distinct retreat from the globalization of the late 20th century towards nationalism and protectionism ("America First" is an echo of 1920s isolationism). A shift from a unipolar world to great power competition (US vs. China/Russia), mirroring the uneasy peace and rising rivalries of the post-WWI era.

• "Pre-Crisis" Atmosphere (High Correlation): A strong sense of anxiety and fragility underlies the technological progress. Many feel the current social, political, and international order is unstable and heading towards a larger conflict or crisis.

Part 3: Conclusion and Final Ranking

While the late 1990s were a powerful echo of the 1920s' tech-driven speculative boom, the 2020s align more deeply and across a broader range of criteria.

The combination of a post-pandemic setting, transformative technology (AI), intense cultural warfare, a retreat from globalization, and a widespread feeling of instability makes the 2020s the clearest historical rhyme to the 1920s in the period studied.
