Self fulling prophecies

Self fulling prophecies are all around us. I find it very interesting how easy it is to create one. For example, our group admin put a table out where people could put goodies (like cookies) to share with everyone. I first thought that there was no way this was going to work. However, I was wrong.

The table of goodies is a self fulling prophecies. She started out by putting a few goodies out there. They looked good and tempting, so people walking by ate them. However, these people started feeling guilty (I'm guessing) and brought goodies to put on the table. The cycle continued. Now the table is covered in goodies!

I've learned that all you need to create a landslide effect is:
1. a simple strategy (the good table).
2. advertising (the email telling everyone what the table was).
3. some initial startup fuel (the first batch of goodies).
