Well we all know there are various reasons why these surveys are often wrong but here's another. This one states that up to 1/3 to 1/2 spouses cheat on each other and look at all the other cheating - sad! Hate to say it but I believe the 1/2 more than the 1/3, maybe more. I know, JMHO :>)
"A nation-wide survey by Ralph Wexler of the Institute of Ethics indicates that 1/3 of high schoolers and 1/6 of college students admit stealing something in the last year. Over 1/3 said they would lie on their resume to get a job. Over 1/2 of college students admit cheating in some way, over 60% say they would cheat on an important test. Other surveys show that 8 out of 10 high school students admit cheating. Likewise, 1/4 Americans think it is okay to cheat on their auto insurance, 30%-50% think goofing off at work is okay, 1 in 6 use drugs on the job, and 1/3 to 1/2 cheat on their spouses. Almost 60% of American adults have used force against another person; 7% say they would kill someone if paid enough; 25% would abandon their families for money (Etzioni, 1993). Furthermore, Wexler says only 2% of students get caught cheating because teachers don't watch carefully; therefore, maybe crime does pay and maybe honesty is, in some ways, not always the best policy from a selfish point of view. What about from society's point of view?
Immoral behavior comes from somewhere. Our current environment is not highly moral or supportive of morality and our society doesn't seem to know what to do about these permissive conditions. About 20% of high schoolers feel a lot of peer pressure to do something wrong. About 80% of teens think schools should teach basic values; yet, 90% of them are already "satisfied" with their values (Ansley & McCleary, 1992) and probably don't want to think seriously about values. In general, many adults fail to provide good role models. Psychology Today (August, 1997) recently reported a survey showing that about half of American workers did something unethical at work this year--padding the expense account, stealing property, lying about what they did or did not do, using sick days inappropriately, etc. Even at the highest levels, half of the top executives admit they are willing to "fudge" figures to look good. More than that, a whopping 75% of MBA students say they would be willing to distort the facts to make company profits look higher. This lack of moral restraint, according to Secretan (1998), is epidemic in the workplace. He says we can change that. Buford & Whalin (1997) take a different approach, namely, change your goals in mid-life from success to significance. Still others suggest simplifying your life by doing what really matters (Aumiller, 1995).
