Honest behavior is much like sticking to a diet - you have to be ready for temptation and consider the long-term consequences.

A recent paper says it is the first study to test how the two separate factors of identifying an ethical conflict and preemptively exercising self-control interact in shaping ethical decision-making.

In a series of experiments that included common ethical dilemmas, such as calling in sick to work and negotiating a home sale, the researchers found that two factors together promoted ethical behavior: Participants who identified a potential ethical dilemma as connected to other similar incidents and who also anticipated the temptation to act unethically were more likely to behave honestly than participants who did not.

"Unethical behavior is rampant across various domains ranging from business and politics to education and sports," said University of Chicago Booth School of Business Behavioral Science and Marketing Professor Ayelet Fishbach. "Organizations seeking to improve ethical behavior can do so by helping people recognize the cumulative impact of unethical acts and by providing warning cues for upcoming temptation."

In one experiment, business school students were divided into pairs as brokers for the buyer and seller of a historic New York brownstone. The dilemma: The seller wanted to preserve the property while the buyer wanted to demolish it and build a hotel. The brokers for the seller were told to only sell to a buyer who would save the brownstone, while the brokers for the buyer were told to conceal the buyer's plan to develop a hotel.

Before the negotiations began, half of the students were asked to recall a time when they cheated or bent the rules to get ahead. Only 45 percent of those students thinking about their ethics ahead of time behaved unethically in the negotiations, while more than two-thirds, or 67 percent, of the students who weren't reminded of an ethical temptation in advance, lied in the negotiations in order to close the deal.

In another experiment involving workplace scenarios, participants were less likely to say it is okay to steal office supplies, call into work sick when they aren't really ill, or intentionally work slowly to avoid additional tasks, if they anticipated an ethical dilemma through a writing exercise in advance and if they considered a series of six ethical dilemmas all at once.

In other words, people are more likely to engage in unethical behavior if they believe the act is an isolated incident and if they don't think about it ahead of time.
