Medical professionals are some of the most trusted people in the U.S., according to new data from Gallup. The polling firm asked respondents to rate the "honesty and ethical standards" of various professions, and the top of the list is full of healthcare professionals. Nurses polled the best, with 85 percent saying they have high or very high ethical standards. They were followed by pharmacists (75 percent high or very high) and doctors (70 percent). Also among the top 10 most-trusted professions were dentists, psychiatrists and chiropractors.
