A majority of people who receive surveys in the mail don't respond. Researchers were curious which type of reward would be most effective: send someone $10 after they mail a completed survey back, or send someone
$5 with a survey as an advanced "thank you that they can keep whether or not they participate.

The researchers chose a random sample of 1200 adults and randomly assigned each of them to one of three
groups: $10 after, $5 in advance, or no reward at all. They found that people in the $5 group were significantly
more likely to send the survey back than people in either of the other groups.
