When finished, a person takes your paper and without looking puts it on a stack of paper.
Do the task.
When finished, a person shreds your paper in front of you without looking at it.
The drop-off rate when people considered it not worthy of their time was the quickest in the shredding scenario, but not much less than the "not looked at" scenario. Strangely enough, people did not cheat.
Rule of happiness #1
Recognition counts more than remuneration.
Give people full instructions how to fold origami.
Ask them how much they would sell it for.
Ask people who weren't involved in the creation how much they'd pay for it.
Change: Give people only guiding instructions how to fold origami.
People who had only guiding instructions wanted to sell the origami figures for much more, whilst the buyers wanted to pay less as they seemed lesser quality than the full instruction ones.
Rule of happiness #2
Having to work harder for something brings pride and a sense of ownership.
