India is fast becoming a superpower, says Shashi Tharoor -- not just through trade and politics, but through "soft" power, its ability to share its culture with the world through food, music, technology, Bollywood. He argues that in the long run it's not the size of the army that matters as much as a country's ability to influence the world's he...
On any given day we're lied to from 10 to 200 times, and the clues to detect those lies can be subtle and counter-intuitive. Pamela Meyer, author of Liespotting, shows the manners and "hotspots" used by those trained to recognize deception -- and she argues honesty is a value worth preserving.
