Science is the study of the world based on observable or unique differences. [IQ statistics](https://www.worlddata.info/iq-by-country.php) and [global crime rates](https://www.worlddata.info/crime-by-country.php) still correlate with this observable data today.
Cultural Marxists changed their definition of science and have the audacity to tell you to "Trust the Science" when it isn't observable and doesn't correlate with observable facts.
