Topic: Prevalence Induced Concept Change

CNN commentator Van Jones delivered an emotional on-air response to Joe Biden's projected victory, citing the difficulty of parenting under the Trump administration. The hosts analyze this as an example of "Prevalence Induced Concept Change," where the perception of racism is amplified by media focus. Jones specifically questioned why Donald Trump singled out Detroit and Philadelphia, cities with large Black populations, for corruption allegations.

A 2018 scientific study discussed by Brett and Heather Weinstein explains "prevalence-induced concept change," where humans expand their definition of a stimulus as it becomes rarer. For example, as actual racism decreases, people begin to perceive "microaggressions" or neutral faces as threats to satisfy a biological search pattern. This "neurological relativism" is used to explain the rise of movements like the 1619 Project and Black Lives Matter.
