Smith-Crowe and her co-authors who are "all interested in this notion that good people, normal people, can do bad things, too" designed four trials. They separated students, primarily business majors, into groups and asked them to unscramble sentences such as, "She spends money liberally," or neutral lines such as, "She walks on grass." Some were shown images of cash, others a landscape.
Afterward, they were asked to make ethical decisions, such as whether they would take copy paper from the office supply room or hire someone for their willingness to share confidential information.
In each study, the people exposed to money or images of money were significantly more likely to do the ethically dubious thing in one case, twice as likely.
"We predicted it, but we were actually still surprised by it," Smith-Crowe said. "We were still pretty amazed the really subtle manipulations we introduced had these profound [effects]."
The next step, she said, is testing whether people can expand that kind of decision-making, known as a business-decision frame, beyond self-interest.
"Is the way we think of business the only way to think about it?" she said. "Is it malleable, can it be expanded to include moral considerations? What sorts of decisions would be made if the business frame were altered?"
Twitter: @lwhitehurst U. researchers used 4 tests to study the effect of money on morals
1. Subjects were asked to make an ethical decision, such as whether they would take copy paper from a university office.
2. Researchers tested whether an image of cash made students more likely to finish fragments with business-related words.
3. Students played a game in which they could be paid $5 instead of $2 if they told a lie.
4. Participants were asked if they would hire a job candidate who was willing to share confidential information, then were tested on whether they cheated in order to earn more money in a dot-identification program.
