In the middle of all of this is a new breed of research corporation that relies on you – the survey taker – to determine this information. For your time? Many survey companies will pay you to take surveys for money or for other cash alternatives like gift cards or physical prizes and rewards. It depends upon the company as to whether they'll offer money or other offers and special deals.
They include sites that seem to be their competitors because they earn referral fees when you buy memberships. A couple mentioned in scam forums even try to dupe you into buying the same list at other membership sites they own under different names. Naturally, these sites also have an incentive to exaggerate how much you'll earn from online paid surveys.
If you're looking to make money by completing surveys online – this site will not be very helpful for you. Like the previous sites, they will take, retain, and sell your information to anyone that waves a dollar in their faces. UNLIKE previous sites reviewed, they hide their consent for that information. It's buried. So not only do you make silly reward points that don't translate to cash but every third party service and product solicitor has your personal information.
IOCS is a not-for-profit research organization that conducts studies and experiments on shopping-related behavior – things like how we, as consumers, evaluate products, how we make the buying decisions, etc. Although the focus is mostly on shopping related behavior, some of their experiments and studies include broader areas of marketing, psychology, and economics.
