Memes are becoming reality, and you’re not allowed to talk about it. The dilution.

Modern day people:

— ‘College students once stood out from the pack on IQ tests. Today, they're about average. A recent meta-analysis found that undergraduates' IQs have steadily fallen from roughly 119 in 1939 to a mean of 102 in 2022, just slightly above the population average of 100.’

Victorians as they were:

— ‘The Victorian era was marked by an explosion of innovation and genius, per capita rates of which appear to have declined subsequently. The presence of dysgenic fertility for IQ amongst Western nations, starting in the 19th century, suggests that these trends might be related to declining IQ. This is because high-IQ people are more productive and more creative. We tested the hypothesis that the Victorians were cleverer than modern populations, using high-quality instruments, namely measures of simple visual reaction time in a meta-analytic study. Simple reaction time measures correlate substantially with measures of general intelligence (g) and are considered elementary measures of cognition. In this study we used the data on the secular slowing of simple reaction time described in a meta-analysis of 14 age-matched studies from Western countries conducted between 1889 and 2004 to estimate the decline in g that may have resulted from the presence of dysgenic fertility. Using psychometric meta-analysis we computed the true correlation between simple reaction time and g, yielding a decline of − 1.16 IQ points per decade or − 13.35 IQ points since Victorian times. These findings strongly indicate that with respect to g the Victorians were substantially cleverer than modern Western populations.’

White people also just suck at breeding.

White people suck at breeding properly.

It also proves that white people have gotten dumber over time.

Why is the IQ of college students today so much lower than it was in the past?
