How to test one's honesty?

There is an interesting article in Reader's Digest (August 2007) entitled " What we found when we lost 960 mobiles around the world?" (page 28) The article is about a group of local Reader's Digest reporters had conducted an experiment to test one's honesty in 32 countries(page29). They conducted their experiment in this way: Two reporters will be in one group, one of them will purposely mislaid his mobile phone in public and the other observed the mobile from a distance. Based on the data collected, they found that only 43% Malaysians return the mobile to the owner after the reporter called them to have his mobile back (page 31). See, Malaysians are very honest!
Having tested the world, Reader's Digest found that 97% of mobile phones left in public was returned in Solvenia (page31). This statistics shows that its residents were universally helpful and can be trusted. Besides that, what's interesting in this article is they compared the old and the youth, they found that young people were just as honest as their elders (page33). Here, come a question, how are we going to teach our young generation if we are the one who do not practice the moral value? Let's think, if you were a mother who saw a mislaid mobile in front of your child, what would you do? Well, will you just simply pick it up ,switch it off and keep it or you will give it back immediately to the owner and set an example in front of your child? Think about it! I didn't enjoyed reading this article because it is too long.
