What if... stay with me here... we married standards with effectiveness?
A brief thread... (1/n)
SCOOP: Army leaders are discussing making long-awaited changes to hair and grooming regulations in the name of inclusivity, including allowing some women to wear ponytails & removing offensive language from AR 670-1.

Final changes are expected in January.https://t.co/iLrYMONloX
A worthwhile natural experiment can be tattoo standards. (/3)
-not allowed if exposed in Class B
-universally waived to include neck and hand tattoos
-allowed but photographed (all not just gang/racially suspect)
-acceptable for enlistees but not officer candidates (/4)
Did we become more effective when they were tightened?
The easy answer is no. Arbitrary standards are, wait for it, arbitrary.

THREAD: 12 Things Everyone Should Know About IQ
1. IQ is one of the most heritable psychological traits – that is, individual differences in IQ are strongly associated with individual differences in genes (at least in fairly typical modern environments). https://t.co/3XxzW9bxLE
2. The heritability of IQ *increases* from childhood to adulthood. Meanwhile, the effect of the shared environment largely fades away. In other words, when it comes to IQ, nature becomes more important as we get older, nurture less. https://t.co/UqtS1lpw3n
3. IQ scores have been increasing for the last century or so, a phenomenon known as the Flynn effect. https://t.co/sCZvCst3hw (N ≈ 4 million)
(Note that the Flynn effect shows that IQ isn't 100% genetic; it doesn't show that it's 100% environmental.)
4. IQ predicts many important real world outcomes.
For example, though far from perfect, IQ is the single-best predictor of job performance we have – much better than Emotional Intelligence, the Big Five, Grit, etc. https://t.co/rKUgKDAAVx https://t.co/DWbVI8QSU3
5. Higher IQ is associated with a lower risk of death from most causes, including cardiovascular disease, respiratory disease, most forms of cancer, homicide, suicide, and accident. https://t.co/PJjGNyeQRA (N = 728,160)

Yesterday, a family of asylum seekers were reunited. Hanz & his son were subjected to #MPP, a cruel policy that forced them into dangerous cities in northern Mexico. We sued on their behalf, allowing them to rejoin their family in Massachusetts. pic.twitter.com/Kce6MTpS9C
