They — along with a great many other high-achieving women — were all once Girl Scouts. So was Sylvia Acevedo. Raised in a poor, immigrant family, she was told that “girls like her” didn’t go to college. But she did, and then became a rocket scientist and tech executive. Now she’s C.E.O. of the very organization she credits with shaping her life. Acevedo tells us how the Girl Scouts are trying to stay relevant, why they’re suing the Boy Scouts, and how they sell so many cookies.

The controversial theory linking Roe v. Wade to a massive crime drop is back in the spotlight as several states introduce abortion restrictions.

There are a lot of barriers to changing your mind: ego, overconfidence, inertia — and cost. Politicians who flip-flop get mocked; family and friends who cross tribal borders are shunned. But shouldn’t we be encouraging people to change their minds? And how can we get better at it ourselves?

Whether it’s a giant infrastructure plan or a humble kitchen renovation, it’ll inevitably take way too long and cost way too much. That’s because you suffer from “the planning fallacy.” (You also have an “optimism bias” and a bad case of overconfidence.) But don’t worry: we’ve got the solution.

The revolution in home DNA testing is giving consumers important, possibly life-changing information. It’s also building a gigantic database that could lead to medical breakthroughs. But how will you deal with upsetting news? What if your privacy is compromised? And are you prepared to have your DNA monetized? We speak with Anne Wojcicki, founder and C.E.O. of 23andMe.
