“Early in 2017, YouGov conducted a poll in the UK in which they asked: ‘Of the following, whose opinions do you trust the most when they talk about their field of expertise?’ Nurses came first. Eighty-four percent of people polled trusted them. Politicians came last, at 5 percent . . . Economists were just above politicians at 25 percent.” Abhijit V.
