What happened to “who”?

Frank Bruni at The New York Times pinpoints a disturbing trend in the political sphere: the use of “that” in place of “who” (instead of saying “people who,” for example, Donald Trump said “people that”).

Doesn’t the “who” pronoun acknowledge our humanity, our personhood—separate us from the flotsam and jetsam out there?

You’re not as smart as you think you are

The Economist‘s review of Steven Sloman and Philip Fernbach’s The Knowledge Illusion: Why We Never Think Alone illuminates an important principle: People often have strong opinions about issues they understand little about. And on social media, surrounded by like-minded friends and followers, opinions are reinforced and become more extreme. It is hard to reason with someone under the illusion that their beliefs are thought through, and simply presenting facts is unlikely to change beliefs when those beliefs are rooted in the values and groupthink of a community.

Humans struggle to explain basic inventions like a bicycle, but still manage to navigate the world with ease.
