We measure intelligence in lots of ways, but at the top of the list is literacy and numeracy. A study published in September 2017 by the U.S. Department of Education found that U.S. adults performed the lowest of all developed nations in numeracy. They also found that our literacy was on the low end of developed nations. Most interesting was the finding that young adults in their 20s from Finland, the Netherlands, Sweden and Japan who did not finish high school had the same literacy levels of U.S. high school graduates.
Study after study shows that the United States underperforms in literacy across the developed world — especially given its resources. But that isn’t even the core issue; the real problem is the way we have consistently devalued quality education across all levels for decades. Consider the fact that 14 states teach creationism in public schools.
Add to that the reality that a Pew Research Study from 2015 found that 34 percent of Americans reject evolution entirely, saying humans and other living things have existed in their present form since the beginning of time. [...]
Public investment in K-12 schools has fallen dramatically in a number of states over the last decade, despite post-recession economic growth. Arizona cut funding for K-12 by 36.6 percent from 2008-2015. A study of investment in education across the developed nations of the OECD found that from 2010-2014 the U.S. decreased K-12 funding by four percent. Over the same period, education spending, on average, rose five percent per student across the 35 countries in the OECD. Even more noteworthy is the fact that in some countries, spending rose at a much higher rate. Between 2008 and 2014, education spending rose 76 percent in Turkey, 36 percent in Israel, 32 percent in the United Kingdom and 27 percent in Portugal.
