Have you ever bought coffee for someone to butter them up?
A group of scientists set out of discover if this angle really works. Before giving university students either caffeinated orange juice or regular orange juice, scientists quizzed the students about their attitudes toward voluntary euthanasia or abortion.
After the beverages were consumed, scientists gave each student a persuasive text countering their stated attitudes on the subject they were tested on. They were then quizzed again about their attitudes toward the subject matter. Students given caffeine were more easily persuaded by what they had read. It seems that caffeine makes you more attentive and, in doing so, makes you more easily persuaded. Also, caffeine puts people in better moods, which may also contribute to their being more easily persuaded.
