First-Born Children *Are* Smarter

“First-born children have better thinking skills, study says” in The Guardian highlights JHR-published study that finds parenting behavior results in cognitive advantages for first-born children.

“Researchers said the findings went some to way explaining the so-called birth order effect – which means children born earlier in a family have better wages and higher levels of education later in life. First-born children scored higher on tests including reading, matching letters, names, reading single words aloud and picture vocabulary tests.”
