Tests Are Bad Predictors of Performance
We live in a society obsessed with performance. Think of exams like the S.A.T. and the G.R.E. Such high-stakes tests, however, are often spectacularly bad at predicting performance in the real world.
Standardized tests are poor predictors of future behavior. "Though the S.A.T. does a decent job of predicting the grades of college freshmen—the test accounts for about 12% of the individual variation in grade point average—it is much less effective at predicting levels of achievement after graduation. Professional academic tests suffer from the same flaw. A study by the University of Michigan Law School, for instance, found that L.S.A.T. scores bore virtually no relationship to career success as measured by levels of income, life satisfaction or public service."
New research links urban planning and political polarization.
- Canadian researchers find that excessive reliance on cars changes political views.
- Decades of car-centric urban planning normalized unsustainable lifestyles.
- People who prefer personal comfort elect politicians who represent such views.
Progressive America would be half as big, but twice as populated as its conservative twin.
- America's two political tribes have consolidated into 'red' and 'blue' nations, with seemingly irreconcilable differences.
- Perhaps the best way to stop the infighting is to go for a divorce and give the two nations a country each
- Based on the UN's partition plan for Israel/Palestine, this proposal provides territorial contiguity and sea access to both 'red' and 'blue' America
Science and the squishiness of the human mind. The joys of wearing whatever the hell you want, and so much more.
- Why can't we have a human-sized cat tree?
- What would happen if you got a spoonful of a neutron star?
- Why do we insist on dividing our wonderfully complex selves into boring little boxes
