Strange. I find the boy who cried wolf to be a really good one. It's still something I think of from time to time. I doesn't stop me telling the odd lie but if/when I consider a big lie I definitely consider the consequences based on that story.
I used to agree with that interpretation until I saw the DS9 episode where Garet comments on the story - and points out that the mistake was to keep telling the same lie and a lie that is easy to very is a lie.
I suspect that the age of the children has a big impact on the results. The study was of 3-7 year olds. If you remember it well then you were at the upper end of that range, if not older.
Why was this downvoted?
Yes. The Boy Who Cried Wolf has other issues, as well, though; I remember thinking (as a child) that it was as much the villagers' fault for not believing the kid as it was the kid's fault for lying before.
