The bigger risk, however, is on the side of the funder - and that's the risk that the project will get funded, you will spend your money, and you will end up getting nothing in return. For original-concept Kickstarter projects, that's probably OK: you supported the arts by funding an artist, and you hoped to get a memento of that funding, but the reward was just a reward, and not necessarily the main reason you funded the project. For things like bars of soap and iPhone docks, however, the great majority of the funders are thinking of themselves as buying a thing. And they're not properly discounting the very real risk that they will end up with nothing at all.
"A great many people think they are thinking when they are merely rearranging their prejudices." -- William James
