Leslie

According to Leslie, those who ridiculed former Defense Secretary Donald Rumsfeld for his 2002 remark that we have to be wary of the unknown unknowns were mistaken.

Although Leslie perhaps paints a bit broadly in contending that most of us are unaware of how much we don't know, he's surely right to point out that the problem is growing: Google can give us the powerful illusion that all questions have definite answers

Citing the work of psychologists and cognitive (認(rèn)知的)scientists, Leslie criticizes the received wisdom that academic success is the result of a combination of intellectual talent and hard work.

Elsewhere in the book, Leslie writes: Google aims to save you from the thirst of curiosity altogether.

Indeed, Google, for which Leslie expresses admiration, is also his frequent whipping boy.

Leslie argues that curiosity is a much- overlooked human virtue, crucial to our success, and that we are losing it.

Leslie presents considerable evidence for the proposition that the society as a whole is growing less curious.

Leslie worries that the rise of the Internet, among other social and technological changes, has reduced our appetite for aimless adventures.

Rumsfeld's idea, Leslie writes, wasn't absurd—It was smart.

The decline in interest in literary fiction is also one of the causes identified by Leslie.

The journalist Ian Leslie, in his new and enjoyable book Curious: The Desire to Know and Why Your Future Depends on it, insists that the answer to that last question is "Yes".

Harvard Business School professor Leslie Perlow explains that when people feel the pressure to be always on, they find ways to accommodate that pressure, including altering their schedules, work habits and interactions with family and friends.
